I'm using a 1/2" snubby open/closed end wrench and don't have a torque wrench - - - couldn't get a socket on but 2 nuts anyhow - - - I need to locate some more gaskets or order some online - - - NAPA is a good shop but out of the 5 items I had them order yesterday they only got 1 correct and I need at least 2 more in case I double those paper thin gaskets. thanks, Roger
