I have a client that has a 2000/ 7.3 F250 and when he is running both WVO and Diesel his fuel pressure gauge is around 70-80 psi. It starts out low 30psi and as the truck heats up it climbs up to 70-80 on both WVO and diesel. I would think that it would be a filter clogging if it was just the WVO or Diesel. But since both of them are showing the same pressure it can?t be. The client placed another gauge on the fuel pressure sending unit and that gauge did read the same pressure as the VoControl.

I had the client first change out both diesel and WVO filters to see if that would make a change in the system. It did not.

I was able to do some trouble shooting to the client?s truck. I was able to disconnect both batteries in his truck to see if that would reset the computer. However it has no effect. I was able to confirm that when the truck is off, the PSI starts reading at 30 PSI and then slowly climbs to around 80 PSI. When the truck is running, and is at idle it does the same thing. It only takes a minute or two for the system to reach 80 PSI. Even when the truck is turned OFF.

The system is a stock greasecar kit for a F250 with a vocontrol system. It has a separate WVO filter and diesel filter. However, the greasecar kit using the same F250 electric fuel pump to push the fuel (diesel/WVO) through the system.

I thought I would check with you guys to see if you had any information on the matter.
