I have done a couple of these pumps, which are referred to as the Bosch VP44. First thing to do is power wash all the crap off of the engine before doing anything, then allow it to dry thorouly, next, take compressed air and a blow gun and blow all of the loose crap you missed with the power washer away from the fuel pump and lines. Getting even the smallest fragment of dirt in the fuel sytem can damagr the new pump and or clog an injector. I am not trying to scare you, just use good common sense and be mindful of the open fuel system. Next small PITA is the fact that the INJ pump shaft is tapered, with a key in it. The pump shaft slips through the pump drive gear, and is secured by a nut on the front side of the gear[facing the radiator]. It can be accessed by removing the small inspection cover on the front engine cover, Remove the nut from the pump shaft, then using a steering wheel puller, thread 2 bolts into the threaded holes in the gear, and carefuly tighten the forcing screw on the puller to pop the tapered shaft loose from the drive gear[the drive gear will stay in the front cover]. Be very careful when doing this that the key in the pump shaft does not fall out of the shaft and into the engine.Thank you very much guys . this is the stuff I want to hear.
You gotta love how the service counter fella made it sound like the whole truck and world would self destruct if dodge didnt install the only MOPAR parts
available to solve the crises.
It really sounded like there were no options. but you guys put me on to the FASS system, which seems good, but im still unsure if the inj.pump should be changed as well. Im not much of an engine guy. but I am of the belife that I can ussually do a job wrong once and then get the stuff to do it right the second time, still for less than letting anyone else do it. and then I know how to do it for sure the 3rd time... if theres a third time.
Yes a fuel pressure gauge would be a good idea. It seems like there is a warning light with the fass to alert of pressures below the required 7psi.

When reassembling, use a small mirror and a flashlight to assist you in lining up the pump shaft keyway and gear,you may have to move the gear up and down a little to get the shaft to line up, just be sure to keep the teeth timed just as they were when you removed the INJ pump[ don't pull the gears apart and rotate them]. Be sure to use loctite 271 on the inj pump shaft gear retaining nut. Good luck and holler if can help you more.
