Message: [QUOTE="gooseman80, post: 1568516, member: 24701"] I'm looking for some opinions. Truck is a 2002 F350 and I currently have the three Dieselorings fuel pressure shim springs. As of right now, i have the black spring in because pressures using the silver and gold were less than expected. Fuel pressure with the black spring in should be between 67-70 psi but I am running a constant 59 psi. This is primarily the reason why I have the black spring in. I know one of the reasons that could be causing this is a weak fuel pump. I've never had a problem with this and the truck only has 178K miles, however, this can't be disregarded as a reason. Note that I purchased this spring kit around the same time that I installed a fuel bowl rebuild kit. The last time I researched this issue I believe it was suggested that I should bypass the fuel tank and see what my pressure is when the pump is directly sucking from a portable fuel tank. Do you think this would be a good start for investigating the issue? Right now the tank is amount 1/2 full and I really don't drive the truck much. Are there other reasons you can think of that could be causing this other than a weak fuel pump? Thanks guys [/QUOTE]
