Yeah although alot of this *new* stuff was put on during overhaul in 2014 but then the truck only gained 13k miles since then. It was a quarry repair truck and didnt see much road use. Might be interesting to cut open an older pump and a newer pump and see what the internals look like and if they differ at all.Hold on to your old mechanical pump. I have been hearing rumors on here the new pumps don't last. That's what you get with parts changing now days. The new stuff is not very good quality, and you end up with more problems than you started with.
You were stating all the new stuff on your truck already replaced. I would not be surprised if your problem was with something new on the truck. For instance I think you mentioned you had a new switching valve, and someone just mentioned a faulty switching valve could be a problem. Might be worth bypassing it to eliminate it as the problem.
It would also be interesting to do a spectroanalysis of the metal and see how they both are cast and alloyed...just for comparisons...and to see if we are getting good, bad, or indifferent types of metal with our replacement parts...as opposed to original equipment...Might be interesting to cut open an older pump and a newer pump and see what the internals look like and if they differ at all.
Ya know, I wonder if I have my old OEM mechanical pump from my last truck. I am a sort of pack rat when it comes to this stuff, I will see if I can track it down.
trying to find fuel injection hose clamps for 3/8" OD tubing
Dangit! I just got a line and fittings delivered this weekend. Thank you for the gesture though.I have a new hard line replacement kit from the lift pump to filter head if you want, Im in CT too. I just replaced my lift pump because it was leaking fuel. I had the hard line delete kicking around the house for a long time, bought it from mike green i think back in the day, but i didnt use it. figured if it aint broke dont fix it referring to the hardline

No worries man, Fixing the truck got me back into it, so im back on the forum for a little bit, till I fall off again lolDangit! I just got a line and fittings delivered this weekend. Thank you for the gesture though.
That is a nifty idea....!!! You sure are a crafty sonuvagun...Alternatively, I could cut the end of the fitting flat and place a Viton O ring inside the pump side and compress it using this fitting.
Side note, trying to find fuel injection hose clamps for 3/8" OD tubing is a pain in the neck. No auto parts store carries clamps this small except worm drives which turn into more of an oval at this size. I did one using a spring sleeve and a 7/16" sized injection clamp but I would rather not do that across the return system.
