I installed a new sedimenter to replace the one that broke and put in a new Airtex 12V fuel pump while I was at it. I also replaced a failed spill line on the motor. Now when I go to run the truck in the morning, it loses power immediately due to air in the fuel line. The electric pump makes it super easy to bleed and continue on my way but I want to solve this.
There are no visible fuel leaks.
Here's what I've checked so far:
- Pulled apart sedimenter and verified that the o-rings were intact. Reinstalled.
- Tightened barb fitting-to-fuel pump connection. The barb was slightly damp.
- Pulled fuel filter and inspected gasket, then reinstalled.
My suspicion is the fuel pump, since that's one of the few things that changed. I was thinking about using some of that white plumbers tape on the threads of the barbed fittings. Is that stuff diesel-safe?
Any other ideas for things to check?
