Tubs, I will triple check tomorrow, but I think that if I put the fuel line on as in your photo below,
with the tapered side “down” (to mate with the bolt taper), then the fuel line will arch down
at the other end, and not hook up to the petcock.
Hopefully I’m just missing something, and the dawn of a new day will shed some clarity
on the situation! Thanks.
Prepare to be boarded!
