I had a spare valve that I tried to give to Dave at the last GMCMI rally. He said that he is not rebuilding them any more. So buying new is your only option. Jim K. stocks made in Ohio (not Chinese crap) new ones and they were about the same price as Dave's rebuilt ones a few years back.

Just go to Jim K. at Applied GMC if you need one or two.

One comment on the plastic fittings. I got fed up with them years ago and simply replaced all of them. At the time they were $1.50 each from my local auto parts store or $3.00 each from NAPA. Assume they have gone up a little but it still will not cost you much to replace all of them. They are make by Parker and available in straight or 90 degree flavors.

A usual Jim K. probably also has them. I have never asked, but he stocks just about everything GMC related except a 30 mpg carburetor.

The system was unfortunately assembled with plastic crimp fittings. In our tenure as an owner three of these have failed usually with body cracks. That is handy that way because if you can get the system pressure up at all, the failed fitting will whistle loudly enough for your wife to hear and point it out to you. The fitting can be removed by using a file to cut the crimp ring and then no tubing length is lost.

All the fittings on my '74 are brass. I just figured all '73 & 74's had brass fittings. The '75 has the plastic fittings and the are a bunch of crap ompared to the brass.

(Note the use of the word "figured" instead of "ASSume")

I never realized that. I just assumed that since all of my 1976 GMC are plastic that all GMCs came that way.
