I just wanted to let everyone know that the problem is solved and my fuel
system plumbing is complete. I guess others have been through this, but
Scott Suhring sent me the solution. The compression beads for old fuel lines
are longer and NLA. Take two regular compression beads and file off about
1/3 of each. Then put them both on the line and tighten the fitting.
Also, the inlet side of the pump is 5/16, not 3/8. The outlet is 1/4.
Also, also, I bought the spring type hose clamps from TRF. These are the
type you normally get with fuel filters. They seemed too large for the 1/4"
hose on the carbs. So I went with other clamps. I tried squeezing them
together to make them tighter, but wasn't confident in the result. I suppose
I'll give TRF a call.
Thanks all.
