Piston Lift Pump Install
#151
Thanks everyone! Now all I have to get is the hard line from the pump to the filter. I think I already have the banjo bolt seals got extra when fixing a previous leak at the VE pump. Not sure if I want to enlarge the holes in the banjo bolt since my pump is stock at present so I don't really need the extra flow. I'm just looking to get some extra mileage from the pump over the diaphragm type. I don't want to weaken the bolt.

Don't get the piston pump from the Amazon link I posted. It puts out over 35 psi. It pegged my meter when I tested it after it blew the front seal out of my VE injection pump and filled my crankcase with diesel fuel. Get the pump from DieselTuff which Nascar Mark has reworked to only put out 14 psi which is safe for the seal.

So the conflicting info I'm trying to weed through is that the 3936320 (now I think 4988751) is both safe and too high a pressure.

So is it that the part numbers have changed and the original pump (3936320) referenced is no longer a low pressure pump? Or were you sent the wrong pump from the amazon seller? Reading through all the threads, it's terribly frustrating looking for a pump that will work. I'm looking for a reliable pump that will support between 200HP and 250HP.

This is the pump I finally got. https://shop.dieseltuff.com/14psi-HV...ump-for-VE.htm

I see. Even some of the Ebay listings including the part numbers mentioned in this thread have some of the applications including 2nd gen dodge trucks so it's getting confusing.
I found a cummins 4988751 (latest part number) that comes with the peace of mind that it would work for $100 from Oregon Fuel Injection. Says specifically it would work with VE pump. Still I would like to go with something cheaper as I'm eventually wanting to just use a 2nd gen pump and a regulator but it's getting to the point that my time slipping by is factoring in.

I ordered 3 HVLP LP kits from The Hungry Diesel.
They worked well and had the right pressure needed for the VE pump.
I am sure the Dieseltuff ones are the right ones as well.
As far as random E-bay sellers I would be wary of them knowing what they are talking about.

Pulling the Inj pump to replace the seal isn't a lot of fun. But I've pulled my pump and reinstalled it 4 times so I'm getting kind of good at it.

Yeah. Just looking for a bare bones basic piston pump that won't blow the seal. Anything will be better than my worn diaphram pump which has been replaced by a now worn walbro pump that was purchased for a 2.4l mercedes a decade ago and slapped on my rig in an emergency two years ago!
