Bob:

I have an aftermarket pump which doesn't have the little priming handle
(which I don't like, because if it ever goes out I am just dead!  I have
managed on other occasions to make it home by pumping by hand and
driving a little ways) and I don't know if it has a pressure release.
Would make sense though.

Thanks.  Any idea would help at this point.

Michael
