Buick 1100HP Fuel Pump – PN 1003

Buick 1100HP Fuel Pump



Buick 400/430/455 Series V8

PN 1102   Dual Outlet Option

The standard outlet port is on the bottom of the pump. This option places an additional outlet on the side of the pump, 180 degrees from the inlet port. Having the choice of two outlet positions can make it easier to run fuel lines to the pump.


PN 1010   Vapor Return Adapter

Allows “vapor return” line to be used. Reduces the chance of vapor lock and regulator pressure creep.
