Genuine Cummins HVLP Piston Lift Pump & Install Kit for 1st gen Dodge
Upgrade your 1st gen Dodge 1989-93 Cummins VE injection pump fuel supply to a HVLP pump.
If you are looking at other lift/transfer pumps & they don’t have Cummins ABFJV cast into them, then they are not a genuine Cummins pump & are just a cheap knock off.
Our HVLP has approximately 50% more flow than the stock standard stock diaphragm pump.
Results are better throttle response & performance for your 1st Gen Cummins
And yes a Bosch VE pump can handle 19psi
The stock / OEM low flow-low pressure lift-pump is of the diaphragm design and produces approximately 7psi and drops to approximately 0 psi under WOT on a heavily fueled engine. (Fuel Lines, Banjo’s, Injectors, Injector Pump mods etc come into play, so your numbers may vary slightly)
Other piston lift-pumps produces approximately 30 psi @ 2600rpms and will blow the front fuel seal out of a VE injector pump and push fuel into the front engine gear case, causing oil contamination.
Our Genuine Cummins high flow-low pressure lift-pump with the supplied spring only drops approximately 4 psi under WOT on a heavily fueled engine. (Lines, banjo’s, injectors, injector pump mods etc come into play, so your numbers may vary).
The crucial part about fuel “feed” pressure is that you need the vane pump supplied with enough fuel that it does not cavitate. The higher the rpm, the higher the feed pressure needs to be to keep case pressure up.
This provides more fuel volume, supporting larger injectors and injection pump mods, while better maintaining feed pressure to your VE injection pump, thus keeping the dynamic timing function of the VE injection pump within proper specifications.
