Hi all,
Could some one tell me what the GM part # is for the 3port white windshield washer pump.
Thank You,
Rob

I think you'll find the off-white Trico pump's as originally installed by the factory are LONG discontinued. If you have the original pump, you can rebuild the parts that generally fail yourself (inlet/outlet nipple, umbrella valve assy and interconnect o-ring) with off-the-shelf kits from your local autoparts store.

The only drawback will be these come in jet black or VERY white nylon today and are visually different from the material that was originally used (slightly off-white in color). Most of the pump repair kits provide two nipple assy's, one with straight in/out ports the other with 90-degree angled ports.

Jack, Thank you.
Why I need the #'s is I met a person that has a GM unopened box from 30 years ago whith a corvette washer pump in it. (He said) If I can get him a part # for my car he will look and see if it is the one.
Thank you again.

The service replacement pump assy for your car (3-port) was 4919630 as of 1972. There may be later service running changes making function-alike replacement pumps, but that's what was used when your car was in the service channel when your car was originally delivered...
