Try a mechanical fuel pressure gauge........remove banjo bolt that holds the hard (fuel) line to the IP and install the banjo of the gauge. My gauge came with a 7' hose, so I laid it on the windshield and drove out and on the street monitoring it all the way. It turned out to be the lift pump............95 bucks at Cummins Northeast in Dedham Ma. I forget where I bought the gauge but it was not expensive at all..........35 dollars or so. I'll do some looking around and get back to you!!!!!!!! Paul

Yeah, a pressure gauge is going to be your best bet. Harbor freight has a cheapo gauge for $15 or so.

Try Geno's Garage, install their banjo in your fuel filter housing, there is a bleeder bolt that can be removed on the top of the housing and Geno's part installed in it's place. Cheap cheap cheap. After all this, if you're like me you'll want to install an electric gauge and be able to constantly monitor pressure. I've looked briefly at gauges for this..................over 250 bucks. Not for me yet!!!!!!! Paul

I installed a wet gauge (non electronic) after the fuel filter and ran the small copper tube through the firewall (in a rubber fuel line as to prevent chaffing) into the cockpit.
Mounted below the dash is my gauge. If you are going to install one, make sure it has a backlight tied into your dash lights. My gauge did not have a backlight and I had to get creative. This is great insurance. When you start seeing lower than normal pressure, you know it is time to change the filter. If you are still continuing to have low pressure (after the filter change), than you know the lift pump is starting to weaken. This is great insurance against destroying your I.P.
I bought 3 lift pumps off of ebay for around $35.00 each (I believe in having spares of everything!) I have a first Gen 12-valve
Good luck.

There are a few problems that could be affecting your fuel supply and I would suggest tacking them in this order:

-First and foremost, a fuel pressure gauge for diagnosing low pressure (a necessity to troubleshooting fuel system probs).

-Check ALL supply AND return lines for air/fuel leaks.

-Change main filter, and clean pre-filter. Pre-filter is shown in that diagram, I can't remember the size socket you need to get it off, but a 12" extension will be really helpful. It just unscrews at the bottom of the pre-filter/pre-heater assembly, pulls apart, and is easily cleanable, no need to buy a new one.

-OFV (overflow valve) is poorly designed, and the ball and seat will eventually wear out. They are a common problem on a P7100 IP, so if your pressure is low and you have new filters/no air leaks, this is your next course of action, again IT COULD VERY LIKELY BE YOUR PROBLEM!. Get one of these, it will last longer, they make them especially for WVO, and the pressure is adjustable:

-THEN you go to lift pump if you're still having supply issues.

-Last is IP.

I wrote up this article as a go to for a '94-'98.5 cummins, so maybe you'll find useful info:

I also suggest reading this for more fuel system info:

I think I may have found an air leak there is a small bolt on the fuel filter cap that sets in front of the banjo bolt it is almost completely stripped But dealer does not sell it I'd have to buy the entire cap for 209.00 dollars for a 3 dollar bolt I have contacted several salvage yards in the area and no dice . It is the bolt that has the fuel line going to the injection pump I'll pay 10.00 plus shipping and handling just to save 200.00 Hope one of you mechanics can help me outr

In my opinion, and this is what I did. I mounted a remote filter, along with corresponding filter head on the frame. I used fuel inj hose from the sender, after removing the steel line. The hose from the sender to the inlet of filter head then out to Greasecar 3 way valve. This allowed me to remove forever the shitty canister that dodge put in. I changed the stock filter a few times, man, what a pain. and messy. The remote is a Baldwin w/ Baldwin head. I made a bracket to bolt to the frame and mounted the head to it. Screw on filter after filling it w/diesel. You could even put a check valve forward of the filter to stop the fuel from leaking back to the tank when parked uphill. I heard somewhere these trucks do this. The spinon filter is much less expensive than the dodge cartridge style.

With my 97 cummins I had an air leak for the longest time. I eliminated the prefilter/heater assembly all together. It's not really necessary. I then replaced the lift pump and the overflow valve. Didn't fix my problem. Later on I discovered that I had a loose bolt on top of the diesel filter. Tightened that and haven't had an issue since.

Just my two cents

Waribu, great post, I read the cummins forum article, I dont do much haulin.....some stones and some firewood, mostly highway.....600 mi/wk, 85 % on veggie. I had to install a new LP 2 yrs ago and chose stock injectors when I replaced them last year. I moved my fuel plate AWF and noticed a nice change. I ordered the tork OFV a couple of days ago and look forward to testing my pressure before and after.
My truck is a California truck with the crossover tube and EGR.
Do you think by removing the tube and egr, making plates to cover the holes w/gaskets of course, I'll gain a whisker more power ?? Thanks for your expert expertise, Paul

Yeah, I ordered the overflow valve from cummins. I think it was one of the easiest things I have ever replaced. Most repairs seem to be much more work than they should be.

My truck is also out of California with the EGR tube and the 180 Horsepower engine with the manual transmission. I haven't consider taking the EGR tube off because it sounded expensive. But I thought you had to replace the exhaust manifold.

I've read where some guys, on cummins forum, have removed the crossover tube and blocked the ports, installed a smarty chip and set it up to delete that code or som'n to that effect. Some just do it and live with the engine light on all the time, etc. Yes, the EGR is expensive 450 or more.......many others have lived without it. Hope your truck runs well, it's a blast drivin that machine.................Paul

Just be careful of this truck if it has a 53 block. Most 53s that are married to a slosh box (manual trans) will fail (especially if a chip was installed) due to the over use and abuse of said motor.
You will have less of a chance of failure if the 53 block is married to an automatic.

OK What is a 53 block? How do I know if I have one and why are they trouble w/standard trannys? Thanks slate, Paul

Paul:

Check for the casting number 53 on the block. These blocks have a casting defect and subsequently have been changed to a different casting. There are several years this block has been in use. I know of some 53s that are still running strong, however, when married to a slosh box and/or chipped, people have a tendency to jump on the truck more causing more strain on the block. Ergo, failure. Automatic transmissions are aluminum. Aluminum will fail before cast iron. I have friends in a small town that predominately drive nothing but Cummins diesels. I call this town Cummins-ville! This is where I got my education on the 53-block situation.

Basically, if you have a 53 block, dont abuse it! You should be fine.
