Pump Extension (necessary on some models) [+$1.25]
Accelerator pump diaphragm assembly. Fits most Motorcraft 2100, 4100 carburetors. Please be sure to check the measurements to be sure you are getting the correct pump.

This pump is the short shaft and does not include the shaft extension. The 2100 & 4100 kits usually include a shaft extension, that this pump does not have.

1 1/2" square.

Made in the USA. Please be aware that even the best quality rubber, or plastic parts will fail if the ethanol is in high enough concentration.

You can also match your carburetor number with the list provided.

pump diaphragm
I ordered this Tuesday afternoon and it was in my mailbox on Thursday. Part seems to work well once I realized screws were bottoming and the pump cover was warped. Corrected by rubbing on a wet stone.

Installed pump diaphragm onto a Motorcraft 2150 carb. The existing leaking diaphragm had the short round center metal connector like this one. No problema. Would buy again from Mike's Carb. Thanks!

Review
Part installed and working fine. Depth of diaphram was deeper than currently installed one (from after market rebuild kit) which is probably better. Arrived on time.
