This side has a Faster casting and couplings that
have pressure relief designed into them. The other side, however, does not have the same setup...which is why I put a like under Tinkerer's post about the 3-way relief valve.
When I finally got a chance to see an old friend of mine of today -- a bona fide old school diesel mechanic and tractor puller -- he made
exactly the same suggestion...and, when I write "exactly," I mean he even gave me a Surplus Center part number right out of his paper catalog.
We were able to get by, this time around, by cracking the lines on the snowblower, but I won't be coming back to the same issue if I can help it. In my mind, the 3-way valve suggestion is a real winner.
By the way, if you live in a cold climate like we do here in the mountains -- and you can't get the collars on your couplings to make that final "click" indicating a positive lock -- get a propane torch out and heat the ends up. That's what ended up getting us over the final hurdle today.
