14psi HVLP Low Pressure Piston Lift Pump & 1st gen Dodge Install Kit
14psi HVLP & 1st Gen Install Kit
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.
Our HVLP has approx 50% more flow than the stock std stock diaphragm pump.
Results are better throttle response & performance for your 1st Gen Cummins
– The stock / OEM low flow-low pressure lift-pump is of the diaphragm design and produces approx 7psi and drops to appox 0 psi under WOT on a heavily fueled engine. (Lines, banjo’s, inj’s, inj pump mods etc come into play, so your numbers may vary slightly)
– Other piston lift-pumps produces approx 30 psi @ 2600rpms and will blow the front fuel seal out of a VE inj pump and push fuel into the front engine gear case, causing oil contamination.
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 fill the chamber in time.
This provides more fuel volume, supporting larger injectors and inj pump mods, while better maintaining feed pressure to your VE injection pump, thus keeping the dynamic timing function of the VE inj pump within proper spec’s. Our pump has the correct inlet fitting and safe fuel pressure for your VE inj pump, unlike the std 2nd gen piston lift pumps, which have the wrong inlet fitting size and too high of fuel pressure. Any metering down of a 2nd gen piston pump with a needle valve or snubber, will diminish fuel flow, which is not effiecent at all, seeing as you only gain safe pressure but at the cost of flow.
Better throttle responce
Protects your inj pump & Inj’s from fuel starvation

Note : A new lift pump will not fix either an air in fuel or drain back problem or a weak or faulty overflow valve.
Please don’t waste my time if you refuse to fix an existing problem or one the is caused by disturbing old fuel system.
Common problem on customers end is : faulty pressure gauge & system, old or improper fuel lines, cracked tank pu, air leaking into hoses or fittings, or fuel heater. Also sludge/debris in fuel system are just a few of the reasons your having problems with fuel pressure/flow.
