Genuine Cummins high volume, low pressure piston lift pump.

Upgrade your 1st gen Dodge 1989-93 Cummins VE injection pump fuel supply to a HVLP pump.

Note, you must run a spacer block with two (2) gaskets or damage will occur to 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 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.

– Our genuine cummins modified high flow-low pressure lift-pump produces a safe 14 psi and drops only appox 4 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).

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.

Benefits :

Less smoke

Less egt’s

Higher HP/FTLBS

Higher timing

Better throttle responce

Better mileage under heavy throttle

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.
