QuestionThank you once again for your response and assistance with my issue.I greatly appreciate it! A couple more questions regarding this came to mind....
1) I have read on a number of your previous posted replies that the Bosch VP44 fuel injection pump is, well, basically junk....SO I am wondering that, if I am having to replace this failing unit with yet another VP44, am I going to innevitably end up with the same issue once again down the line?
2) Also, since replacing the fuel filter and the fuel transfer pump in the tank is more economical first step in fixing this, could you point me in the direction of some instructions to replacing that in the tank pump?
I have seen some of the Bully Dog Fuel Pump Systems for this truck, that claim they help in keeping higher pressure and more feul delivery to the injection pump, and can increase the life of the VP44. Is there any truth in these claims?
Thanks greatly!!!
Regards,
Alicia

Thank you for your quick response to my question regarding my Dodge and it's fuel pump issues. How difficult is it to change the pump in the tank? Also, I would greatly appreciate your assistance with instructions on installing the fuel pump on the engine.
I had been under the impression that they no longer made the pump that mounts on the engine block, so it had to be put in the tank, and new wiring and such run down from the old location, to the new location in the tank. (I am not sure if I am describing this well....) Sounded like a headache... So, my fingers are crossed that this is not in fact the case.
Thanks,
Alicia

Yep, another one of those darn fuel pump issues from that era of the Dodge Fuel pump problems. I am just shy of 80,000 miles, and all was grand, till the other day and the engine started "surging" , my first thought was "fuel filter" and actually had planned on changing that out this past weekend anyway, so went ahead and did that, as well as an oil change, and cleaning the good ol' K&N air filter. She ran better....at first, then the surging started up again.... CRAP..... gotta be the fuel pump. Already had it scheduled to go into the shop to get the Transmission serviced, pan dropped, gasket shanged, etc.. etc... and they confirmed that it was the fuel pump and most likely the fuel transfer pump as well, and gave me an estimate. OUCH! I know that this generation of the Dodge Cummins the pump is located mounted on the engine block, and since Dodge has changed and it is now located in the tank, and needs to be set up like that.... Sooooo.... if one is handy with vehicles. I know my way around them rather well, though newer to the Cummins (Sorry.... born and raised Chevy girl.... so of course the family is giving me crap about straying from Chevy and having trouble after trouble... blah blah blah), and my Dad is great with vehicles as well. Is this a job that we would be able to tackle, or should I bring it in to have it done? Also, could you recommend any good parts dealer and or shop in the Sacramento, CA area? (I am located in Grass Valley...)
Thanks much! I look forward to your response!

The fuel pump in the tank will have to come from Dodge but the fuel pump on the engine you can purchase at a distributor.Cummins West,Inc in West Sacramento.Phone is 916-371-0630.Call parts there for a pump price.It will not be a really difficult job to change the VP44 fuel pump but I would change the one in the tank first and drive it for a while to see how it does before I spent $1500 for the VP44 pump.Write back if you want to know how to install the fuel pump on the engine.

The fuel pump on the engine is not too bad.Need a gear puller & 2 8mm x 1.25 bolts to remove fuel pump gear.Need to put engine on TDC #6(key way up),remove fuel pump nut(27MM or 1 1/16),& pop gear loose.Remove all fuel lines from pump(there are 2 bundles of 3),remove 4 mounting nuts,lower brace bolts, fuel lines from side of pump & wiggle pump loose.The key in the pump times it to the engine.
Answer Well they have changed up the VP44 fuel pumps but I can not tell you exactly what they changed to make them better.At $1500 a pop I would be worried about the pump life due to aftermarket devices.But I hear they "wake-up" those engines.
The pump in the tank will either have to remove the tank or bed to gain access.A few stong men and several bolts takes the bed off.
