The Dodge/Cummins get fuel from the tank to the injection pump with an electric lift pump mounted on the side of the engine. These are sort of an Achillies heel on the Dodge but several aftermarket companies have come up with better pumps to solve the issue.
Mine was failing (evidenced by falling fuel pressure even with a new filter - and an intermittent inability to accelerate) so I ordered up a Fass upgrade pump which arrived yesterday. The pump looked excellent and the kit was very complete including an inlet filter which is missing in the factory set-up - and it's American made.
So everything looked straightforward and I tackled the installation. That's when I encountered the instruction manual which evidently was written by one of the great American fiction writers. The pump is hidden under the brake master and a bunch of other junk and there was no mention of how to dig the offending junk out of the way to allow access to the working area. In fact, they didn't even mention that there might be stuff in the way. It turns out that you have to unbolt the filter assembly and move it to the side and you better have a tool selection as vast as mine before attempting this install - and a hoist doesn't hurt either.
So their "1/2 hour" installation took about 7 hours - and MAN am I stiff! I used all of my 60+ years of mechanic tricks to get that sucker in there. Granted I could do a second one in 1/3 of the time but a decent manual could have warded off many of the unnecessary back-tracks that were required to get this sucker (literally) in place. I now have 16-17 PSI of fuel pressure which is more than I ever had.
All in all, I can recommend the pump but not the manual. If you know anyone who needs to do this installation Email me and I can steer them in the right direction.
