So tonight I decided to set my Holley floats when all of a sudden the Camaro would no longer run (again), no fuel. This is my 2nd new Holley (manual) fuel pump... So I removed the pump, diassembled, and found the end of the pot metal arm that fastens to the plunger was broken again. I removed the fuel pump mounting plate thinking my rod is to long, and now I believe it is. It measures 5 15/16" long end to end and is a Comp Cams #4620. In reviewing the Comp Cams website this part number is for an Oldmobile Rocket Block. Anyone know for sure how long the stock SBC fuel pump rod should be?
Thanks,
Damon

All '55-up small-block Chevy fuel pump pushrods are 1/2" diameter by 5-3/4" long.

Just order the 4607 model Comp Cams SBC fuel pump rod... Why the engine builder choose the 4620 Rocketblock I do not know. Thanks for the measurement of 5.75", that explains why my fuel pumps only last about 10 minutes....
