I have been working for some time with my shims and have had bad luck with housings and weak springs. I found a cheap fix. I bought the FPR cap from DI with a 1/8npt port. I removed the factory reg. parts and installed a $20.00 reg. kit from a rice rocket site online. It came with a 140psi gauge and a boost or vacume reference port. I use the hose , fittings and mount from the kit to put the reg. on the outside ALT. bolt. I test ran at 15psi and pushed for a second all the way to 140psi. I wish now I had done this in the first place. Hope to get the boost reference line on this week to have an increase in fuel pressure at WFO. |

Still using the stock fuel pump or you have many spares?

Hey Bill, I get asked this all the time. Bosch says the pump is capable of 100psi with no harm. I have a Walbro also which is claimed to sustain 150psi consistantly. I'm a pack rat and I have three Bosch pumps. Not for backups but for my air fuel seperator projects. I have two running at 5psi that are awsome. I want to try my new steel unit with high pressure driving out the air. |

I know the stock pump can handle 100 psi on short term but continuous over say months I'm not sure of. What do the heavier duty aftermarket units usually run for on our 7.3L's?

I have a little over 30,000mi with the 95psi setting and over 100,000mi on the pump to start with. Today I'm removing the return line. Can't really see a need for it. Warm fuel in the tank causes condesation, or water, to form in the tank. With my pusher pump, Cyclone fuel air separator and Raycor water trap, I should have a smooth system. |

Condensation comes from warm, moist air contacting something cold enough to bring the air temperature down to the point of 100% relative humidity and then moisture has to drop out.
I don't see how warming diesel fuel is going to generate moisture.
Are you concerned about the build-up of heat in the fuel while it is slowly going thru a pump that is pushing it at 100 psi?

The way it was explained to me was that a fuel tank less than full of warm fuel cools down after shut down and it rains in the fuel tank. I don't let any of my diesels run to low to often but per gallon burned, my big trucks collect way more water than the little psd does. The 7.3 returns very little fuel which is good from some stand points. I'm running this week without a return except for mt "Cyclone air seperator". |
