QTY

Your info says this 512-1 regulator is for a Holley Projection throttle body but it does not mention anything about filling a Holley Avenger throttle body! My Holley parts list that came with my Holley Avenger throttle body uses the 512-1. What's up?

Asked by: Robert
Holley 510-512-1 if holley states the 512-1 is the service part for your throttle body than it is correct.
