Instantaneous response! Pull strongly through the RPM band! A
"must" for tunnel ram setups! This kit is for those who
demand ultimate performance from their Holley carburetor(s). The
Holley 50cc accelerator pump will substantially increase fuel
capacity over the standard 30cc pump system. Eliminates flat spots
off idle or at any other RPM range. This kit includes everything
required for easy installation including new pump housing, arm, diaphragm, spring and longer pump housing screws.
These stainless steel throttle return springs are universal. Can be used in
numerous applications. These springs measure 5" in length and 1/2" in OD. They
can be trimmed to length.
The linkage bushing set allows the attachment of a 1/4" fastener to the
1/2" diameter hole found in the throttle linkage plate of Holley four
barrel carbs. Split bushing design permits simple installation and
eliminates the sloppiness present when rubber bushings are used.
