Befor anything I want to thank all for their replies and help it’s greatly appreciated.
I have a 2000 international 4700 dt444e engine made oct 1999. I’ve been having a fuel pressure problem that is putting me at a stump. Before I couldn’t get around the corner without her choking and dying on me just to restart normal and get another couple hundred feet and die again. I’ve swapped the Icp,ipr, orings on injectors and fuel pump. The truck now runs and drives sounds perfect and fuel pressure picked up whenever demanded. But she starts and only sits at 20psi. Whenever I review or drive out sounds fine no Injector clack no smoke no sputter or choking. Driven it for 50miles on the highway and fuel pressure bounced like crazy between 20 and 50psi but would always settle at 30ish psi while doing 70mph with no clack or loss of power. I know this isn’t optimal for the injectors so I don’t run the truck really since it goes otr a lot. Only thing left to replace for me is the fuel pressure regulator to have the whole fuel system redone besides every line but lines been checked and no cracks or leaks. How would I go on finding the problem that’s causing low fuel pressure. Everything’s stock no mods.
