Re: Get the keepers off the valve stem
Krap, that's a great idea. I have a compression tester I bought at the flea
market for a couple of bucks and the hose comes right off. I'll take that
and get a fitting for the compressor. I might be able to borrow one from my
maitanance dept at work.
Thanks for the great info.
