68 GMC original style winshield washer pump.

[68gmsee]

fyi: I just bought a new original style windshield washer pump for my 68 GMC and it doesn't fit the original motor mounting holes. The vendors don't mention that there are different motors and I didn't know there were either. Both are Delco motors but have different numbers on them.

The mounting holes on the new pump are farther apart than the original pump. Also, my original motor has a metal star pump actuator (not sure what it's called) that's taller and the 69 Chevy has a nylon star one.

Be sure and measure yours if you ever have to replace it.

These are approximatel measurements.

68 GMC washer pump holes are app. 3 and 7/8 inches apart and the new one (similar to the one on my 69 Chevy) app. 4 and 7/8 inches apart.
