Vince,
Thanks, I think that my 46 is not a pressure system. I have looked for a
cap in the auto parts stores and none of them carry a cap without pressure.
What I could get is a cap with a release and leave it open. I have looked
in a few of the catalogs and Carter and Chevy of the 40's both offer a
nonpressure cap and a 3 lbs cap for the 41-46 if you have a pressure system.
I do not know how to tell if I have a pressure sytem. Can anyone on the
list provide a way to perform this test? What would puting a 3 lb cap on a
system not desinged for pressure do? What would happen if you run a non
pressure cap on a pressure system?
I will not test this to see;>
Thanks,
Jim House
