Cummins 4983584 Diaphragm Lift Pump for stock VE inj pump
4983584 ve lift pump
Contains one (1) Lift pump & one (1) gasket.
This pump supplies 5-7psi at idle and 4-5psi of fuel pressure under normal load
to the VE injection pump, on a stock engine.
Recommended to run one of our modified 14psi higher volume, low pressure piston lift pumps
if you have turned your injection pump up or running bigger inj’s, as pressure with a diaphragm lift pump will fall below 3PSI under load.
Cummins states “under 3psi will damage your inj pump”.
Has superseded Part Numbers 3901425, 3904374, 3928143, 3966154 and 3907880.
