O-ring source
I checked with Precision Airmotive on the specific part number for their version of an O-ring, which they said could be used in conjunction with an AN815-4 union (straight fitting) on the Silverhawk fuel outlet. That is a Precision part number 951787 whcih they claimed would be available through a Precision distributor.
Anybody found a $hipping friendly source for that o-ring?

Parker's number is 3-906 for the correct o-ring to fit a 3/8" o-ring boss fitting that meets MS33649.
McMaster-Carr's aviation department sells them as part number 1201T294, $14.82 for a bag of 100 in mil-spec Viton fluoroelastomer.

Since it's never been used, I just took the O-ring off the fitting that was on there, and put it on the new one. That's OK, right?

Most likely. As long as it wasn't cut or nicked, it'll work. Obviously an inspection item (around the fitting, for leaks) after you get the engine running, but it would be in any case.
