I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle.

If there is any reason I cannot get a positive rating please let me know.

Do you have a water in fuel light on? Which pump did you replace? In tank?

Did you bleed lines?

Customer: replied 1 year ago.
I put a new fuel filter and there's no water in the fuel. This model truck has no pump in the tank. The high-pressure fuel injection pump is what I replaced down in the valley.

It has been a couple of days since I have heard from you. Do you still need assistance? I have also noticed that I have not received a rating from you. If for some reason you question did not get answered please reply. I am only compensated for my time when you leave a positive rating. Your understanding is appreciated.
