Greetings list;
I had to rebuild the vacuum pump on the old M-715 truck when I got it. Memphis Equipment had the rebuild kit (which was a collection of gaskets in a sandwich baggie) for just a few bucks. I pulled the fuel/ vacuum pump off and rebuilt the whole thing in about an hour. Once installed both systems work just like new. The only thing that I would have liked to replace was the hardened steel pin that the plunger arm pivots on. It had a groove worn on one side and I had to reuse it by turning it 180*. I guess it will go another 30 years now. Give Memphis Equipment Co a call and see if they have the kits for M-37...I'd bet they do.
Best of luck,

Correct!! Now all you need to do is find a new diaphram replacement kit for
the vacuum side of the fuel pump and hook it back in siries with the vascuum
line and (should be) Voila!! Correct operation of wipers with the throttle
closed or open.
