Quadrajet High Performance accelerator pump assembly.

Complete with new springs and retainer.  The bottom return spring is stainless steel to resist rust and the top spring is chrome vanadium spring wire and will not loose it's tension in long term service.

This is the shortest length accelerator pump available for maximum fuel delivery on acelleration and a direct replacement/upgrade for the Edelbrock 1910 850cfm Quadrajets and all Marine Quadrajet carburetors.

Perfect upgrade from a stock pump for all drag racing, circle track racing and other high performance applications.

It will replace all stock accelerator pumps in any year Quadrajet carburetor.

The seal on the pump is grade five fluoroelastomer and fine in all modern fuel blends, even E-85, straight alcohol or methanol.  It comes with a lifetime warranty.

The seal on this pump is NOT the same as the cheap/soft blue seals that show up on other pumps.  We have been replacing the cheap seals on currently available pumps with our seal dating clear back to 2003 and have not had a single failure.
