Engine Performance problem
1992 Ford F150 6 cyl Four Wheel Drive Manual
I am having a problem with engine performance while running off the front tank. I have to start the truck about three times before it stays running and when it does the RPM's are only around 500, and the engine seems to be losing gas pressure and jerks around. When I run off the back tank the RPM's is up at around 1100 to 1300 at idle and the engines seems to run very smooth. The rear tank has a leak so I do not use or fill it with gas, but it seems to be leaking all the time but never great amounts just drips. I did change the fuel filter and there was no change in the performance of the engine.
So my questions are as such;
1. Can a bad check value on my rear gas tank fuel pump reduce the fuel pressure of the front tank?
2. Is my front tanks Fuel pump bad?
3. Is it normal for some fuel to return to the tanks?
have the same problem?
