Been having a problem with truck stalling after a run on the freeway. It seems to be fine around town. fuel pressure at 8 then on the way home it dropped to 6 and as i came to stop at the off ramp it stalled had to crack the injectors then fuel was back to 8 and fine. Somehow air is getting in. Could the injectors cause this ? some have 500,000 miles on them.

 

If you don't have any visual fuel leaks then it is probably a suction side air leak. One way to find it is to pressurize the fuel tank with a couple of psi's and wait a few minutes for leak to show. Mine tuered ot to be a split in the tank line to lift pump connection...Mark
