I have a 4-154 non turbo perkins diesel, #1 in rebuilding my boat i insalled a second Stainless Steel tank under the rear Deck area cleaned it hooked it all up and it seemed to work great, Now when i switch to it, The engine will run for a min and then start starving for fuel and shut down ? all vents are clear and i can draw from the tank no problems unhooked ? it was a Gas tank i cleaned it added a fuel return and it seemed to be fine any ideas would be great ? #2 my perkins seems to idle to high trouble shooting with everything i can find on the motor my only issue is the fuel pump that pulls from the filters and tanks is electric, I am unsure what PSI i need at the Injector pump and would this have any effect on idle ? locally i was told 3 to 4 PSI is all i need for the 70HP. if i am getting 10-20 psi is this causing the fast idle. I have Been asking about this motor since i bougth to boat, At best they said it was an industrial engine and the pump was changed to a automotive type when it was changed to a boat engine.
