fuel pump dripping


Recommended Posts

The fuel pump on my 01 has a drip comin out the inspection cover at about a drip every 2 seconds. I was wonderin if any1 else had experience with this and if i'd hafta puLl the pump off 2 fix it. I was told by a local diesel tec that its an alligator tooth shaped rubber seal thats leakin. Any help is appreciated!

These OEM lift pumps (fuel pumps) are very troublesome & prone to failure. Dodge's fix was a in tank pump which was expensive & hard to service & no more reliable than the on engine pumps. The VP44 Bosch injection pump, the 24 valves are equipped with, has proven to be somewhat fragile & ultralow sulfer diesel argueably makes it worse. For these reasons, you'll find many of us have gone to higher capacity & more durable after market fuel pumps like the FASS, AirDog, or Raptor. The higher volume helps to cool the VP44 IP. Big line & more open fittings kits also help the fuel volume. Additionally many of us are running 2 cycle outboard type oil as a fuel additive to make up for the lubrication lost in the ULSD fuel. This will support more HP but more importantly improves life of vital components.Running the VP44 out of fuel because of lift pump failure is a prime cause of Injection Pump failure. If you don't like the cost of a Lift Pump, you sure are not going to like the cost of replacing BOTH the lift pump & the VP44. There is discussion of these issues on many threads.Russ

the OEM pumps really arent worth trying to fix, and as far as i know they dont make a refurb kit....the cheapest OEM style pump i have found was about $180.00 and for the extra $80.00 or so, you really should consider getting a raptor, they arent the most expensive but i love mine....

My luck says tightening the two cover bolts won't stop the leak, but hay, it can't hurt to try. I wouldn't wrench them just snug them up a little.

 

I've noticed a few times that the lift pump and injection pump are often confused in a discussion. It's good to be specific about which of the two are being referred to. :smart:
