1999 F350 7.3l diesel conversion?
January 14, 2006 - 10:53am
Is the 99 F350 a good conversion vehicle? At 11 mpg, it seems perfect, but how does the IP handle it?

I believe there were two different setups used in 1999, and it makes a difference in how you run yours. There is a lot of info on the Frybrid forum on this vehicle. But it appears that is not the place to buy the kit these days.
info@greasecar.com may have all the answers too.

The Powerstrokes are great conversion candidates, particularly the 99-03 7.3's (Gen IIs). That is one reason I bought my 99 F250. There are many specific kits: Neoteric (Plantdrive, Frybrid and FN74 (Vegistroke) and of course right here, Greasecar. In fact there are more kits specifically for the 99-03 Powerstrokes than any other vehicle. If you have some specific questions you might ask Jason at www.vegistroke.com - ALL he does is Powerstrokes.

Well, I have a 99 250. There is no IP on these PSD's, the fuel is pressurized in the fuel injectors by a high pressure oil pump that drives the injector. It works awesome, seems like it was made to run on WVO, smoother, more power and a little quieter. good luck

ronmcor -
Did you use a kit or assemble the components yourself? Did you deal with the deadhead issue?

put it together myself. I put an aluminum billet turned to look like the stock filter in the housing to fill the void and reduce purge time. Deadhead? are you talking about pumps? I used a second stock fuel pump for the vegoil and they operate automatically on a SPDT relay. Purge time is about 30 seconds to purge vegoil up to return point then it runs on diesel for about 3 minutes to burn off veg beyond that to the injectors.

hey, do any of you guys that have the Powerstrokes ever have a problem with the injector wiring 'getting loose' (according to Ford)?
I've had my '01 F250 since March 05 (about 13k miles) and had a problem early on (service engine light, rough running, some stalling, etc) and was told by my local Ford shop that it was a known problem - the injector wiring (which controls the injectors I guess) gets loose due to poor design, so they need to put in a $20 injector wiring harness (though the labor will cost ya $200 or more...)
I had the passenger side done, which seemed to resolve the problem, however I have been having problems with the driver's side more and more often.
The problem seems to occur occasionally upon hard acceleration, or during excessive rain (though I think a severe temperature swing contributes as well).
Guess I gotta pony up some $$ and have the Ford shop rake me over the coals again.
By the way, my F250 also seems to love the veggie, though I swear I think I get about 12-15mpg if I'm lucky...

maybe you drive like my wife.............I've not heard of anyone that low. I am up around 17 as well.
January 17, 2006 - 11:28am
#12
hehe, how does your wife drive?
I try to make a point of keeping my OD off until I get to about 45-55 mph - thought that would help my mpg (and it seems to have a bit).
I'll admit that I sometimes do hammer it a tad...
Any input on the injector wiring harness thing would be great - even if it's just to say 'yeah, I had the same problem'

ronmcor,
can you also email me the info you emailed to Forrest? (email below) Or perhaps post it on the forum. I too like Forrest have an Excursion. I also need any aux tank info if anyone has any.
as always, thanks to everyone!!!

Lets just say that second gear in our Saab is her favorite....I will email to you as well. Its a diagram of what I have and a picture of the aluminum billet. I have since made some mods like a timer to leave in purge for 38 seconds automatically (the time it takes to "see" clear diesel in the return line). and a timer to keep the truck running by itself for 3 minutes if "speed racer" purges a little late on the way home and turns the truck off a little early.

it just drops down in like the plastic filter and replaces it. Thats not the filter head you see, its the filler for the plastic filter that was removed. I sent you 2 other pics in seperate emails. i tried photo bucket but the diagram is a .wmf format that they wont accept. sorry. I am going to send it as an attachment instead of embedded.

Forrest, I've had good luck with a replacement PSD fuel pump for the WVO. it delivers the umph you need, 55-70 PSI. I also use a seperate diesel filter to keep it seperate from the VO. You need to be careful as it is on the pressure side. Most filter heads are rated at about 35 PSI. I ended up using a Perma-Cool from JC Whitney that has a working pressure up to 90 PSI. The nice thing is, it was only about $35.
January 17, 2006 - 4:53pm
#25
so you bought a new stock electric fuel pump for your diesel and used it for the veggie side? and the pic of the filter head is for the veggie.? why didnt you just buy another stock diesel filter head and filter for the veggie side? that way you would have the WIF light and the change filter light..

You probably missed the post 3 above your last. that aluminum "thing" drops into the existing filter holder (the same on you have) for no other reason than to take up space and cut purge time. I will get the WIF light because all that is still there. This utilizes the existing regulator, heater, and WIF light that is already in place for both diesel and veg. it does have seperate filters for each fuel. i use a perma-cool for the diesel on the pressure side and a Davco 234+ for the veg on the suction side. And yes I now have 2 stock fuel pumps that are only turned on when that particuliar fuel is being used. I did it this way to keep it simple and have completely different fuel paths up to the original fuel entry point into the existing housing. Some of the other designs scare me a bit because if one of the components go bad you would lose both diesel and veg. Hopefully you got the diagram by now and can "see" how I did it. ron

right now i am working on a new filtering system. it will use baking soda, salt and a cheap centrifuge we can all make. i am hoping to work on it this weekend when i get home. after i get it started i will post pics on here so everyone can help me... but first i have to finish Swimgyms (Karens) filter set up. the thermos should be in when i get home..

again thank you. i now understand what you did. this is what i want to do for the wifes truck. i might need to get ahold of you when i get ready to do this...

Sure, if you need some aluminum billet I still have about about 10 inches left. You can have it but you'll need someone to turn it on a lathe to match the dimensions of your filter. Let me know and I can put it aside. R

Ron & Forrest-
Thanks for all your assistance. I do like the Greasel concept for tanks in the Excursion (HUGE main for Veggie, aux for diesel), but I'm not ready to have a custom tank fabbed for me. I recently got a quote for over $1k. I hope to find an "off the shelf" or maybe a 1/2 ton truck tank that would fit in the area by the frame - still searching. I'm also not to fond of the placement of the fill tube for the aux in the Greasel kit.

I'm sorry, yes I do use their filter. Mostly because of the pressure rating.

Forrest, I'd be remiss not to tell you this. When I was installing this I did cheat and try to get away with a Racor 690 (very nice, somewhat expensive filter). I twice developed diesel leaks around the rubber seal on the spin on element (one was significant enough to scare hell out of me). I use the perma cool cartridge itself as well as it may (or may not be) a reason the pressure rating on this filter is high and I really dont care to find out the hard way again. You need the high pressure on the PSD because it has to push your fuel all the way into the injectors (a job normally done by an IP). BTW I had an earlier post regarding a needle valve. do you have any idea what I can use for this on my sisters cummins? I want to use an "extra" psd pump I have but need to cut down the pressure. any help would be appreciated. thx

sorry no i don't.
why didnt you use a stock diesel filter houseing and filter for the veggie side???you said you bought an extra stock fuel pump. from ford or parts store?

Forrest, I like the Davco because you really can "see" when its almost time to change it as well as the liquid heater, thats why I used it. I see no reason why you couldnt use a generic filter for the veg as its on the suction side, in fact as it turns out I could have used the racor 690 for it but had already purchased the Davco. I got the pump and Advanced Auto Parts for about $150. (but I suppose you could go to Ford and pay $500 if youre loaded like swimgym).
You got me a little confused, do you want to use the current filter and housing for the veg? If thats the case the short answer is no. Your purge time would be high and if you were going to go that route you could use it for both fuels.
January 20, 2006 - 9:27am
#42
ok now i am confused. which filter and housing do you use for the veggie? and the veggie pump is a stock ford diesel pump? so my question was. since you bought a ford stock diesel pump for the veggie pump. why didnt you buy a stock ford diesel filter and housing for the veggie side. then you can carry and buy 1 kind of filter. and i understand about using just 1 filter for both and the purge time. that is how my 97 is set up. and yes the purge time takes awhile..

Thats just it, mostly the purge time. The stock filter housing is a ford product that mounts to the high pressure pump. Where would I have put it? The stock ford filters are about $30 each and very small. (the davco filters I get from fleet filter cost me $5) The regulator and wif light are integal to the housing, (well the regulator sits outside of it but mounts to it). I just thought it was a much cleaner way to do it, and it works well.

The deadhead issue is the #8 injector can get fuel starved because the fuel rails "dead end". Look on www.ford-trucks.com/forums/forumdisplay.php?f=31
for good PSD info - probably the best PSD forum around.
Can you email me your design also? I thought I had a design figured out but now I'm rethinking it.
January 20, 2006 - 9:48am
#46
because then I would have had to use a perma-cool for the veg as well due to the pressure and I've read that most filters are more efficient when used as suction filters. I also mounted the pump and filter in the p/u bed near my tank. But I see no reason why you couldnt use another high pressure filter and push through both.

I have read about that issue, but somehow I cant see the difference between deadheading it with a plug (like it is), or deadheading it with pressure. But when you think of it (with other methods) its really is just deadheaded with pressure in the other direction. The only advantage I see there is a very fast purge time. Another disadvantage is that ford did compensate by using a different injector in the end positions, by feeding it from the other end of the rail arent you really negating that "fix"? and yes, I will email you that diagram.

perma-cool for the veg as well due to the pressure ..
so you use the stock diesel filter for diesel and the perma-cool for veggie? or the other way. sorry i am getting so confused. i thought about leaving her diesel side alone. use the stock pump and filter. then setting up the veggie side with another stock pump and stock filter and housing.

well, if you want to do that then where are you going to regulate the veg? Where are you going to tie into it? Where are you going to tie into your return? I think this is where you may need Greasecars propriatory interface manifold and "special regulator". If you just think of your existing housing as a regulated common fuel path and then tie both your fuel in and out of it via switching solenoids you will have a very simple method of accomplishing the same thing. The only thing you now need to do is fill your existing housing with "something" to take up a lot of space that increases your purge time.

This is how Plantdrive does it. They replace the stock filter with a 'plenum' that handles fuel distribution and add a diesel filter separately. Their VO supply has its own components. Both fuel supplies feed the plenum.

From everything I've read, the 7.3L power strokes make excellent conversions. I know Forrest Gump on this forumn has one, and has logged many thousands of miles on veggie.
