My truck is hard to start after sitting even for a short time.  I have replaced the washers on the banjo fitting back of the head, the seals on the T fitting, and the fuel line to the tank.

I just pressurized the tank with air there are no leaks I can find anywhere.  It has new injectors and new crossover tube O rings.still has the same problem.   No fuel in the oil.  Any suggestions from the experts?

Just to follow up with this I just replaced the fuel lines and mounted the lift pump on the frame.  Not 100% sure but I think the hard fuel line on the return from the banjo fitting had a small crack under the protective hose going down to the frame,. There was a clamp  on the bottom of it after I put air pressure on it the hose was full of fuel.  I replaced everything and now it starts with the front on the shale pile at a 45 deg angel. The leak was so small I don't know for sure if that was the case or not, thank the good Lord it is working great now,.    Thank everyone who helped me on this site.

 

So you replaced the entire hard fuel line? Where did you find the replacement at?

I replaced the return with 3/8 rubber hose, the feed with 1/2 in rubber hose mounted my DDRP to the frame in front of the fuel tank

Hmm, I might have to look into mine and see if I can see any possible kinks and maybe do the same.

Wasn't really that hard to do,. I welded up a bracket to mount the pump.  I have a backhoe to lift the bed,. I also have a fifth wheel so had to remove the bolts that holds it to the frame.  Will post a pic if it ever stops raining.
