GL03 submitted a new listing:

New Rochester 4GC accelerator pump - New Rochester 4GC accelerator pump

Came off a KEM kit for GM Rochester 4GC rebuild.
The accelerator pump is 3.250 " long fully extended.
2 7/8" fully compressed.
Diameter of plastic where the cup sits in is 5/8".
I think it takes a 21/32" cup. Could work with 5/8," but,
if you multiply 4(5)/(4)8= 20/32" you make the assumption in respect to wear, polishing chamber, etc.

$1+ shipping we will determine that later, unless you are local to pickup in LA.
