Mark and Scott

The NAPA pumps that I purchased from Tracy were marked Carter 2H26A380 and
the screw in barb adapter was a 5/16-24 thread. I was unable to find any
source of 5/16 to AN6 adapters. I obtained the Earl's 991953 fittings which
came with soft aluminum seal washers. Using a 23/64 drill and both standard
and bottoming 10mm-1.0 taps, I was able to cut several almost complete
threads to match the Earl's fittings. After removing any trace of cuttings
and carefully smoothing the pump face, I installed the fittings using the
aluminum washers and fuel lube on the threads. They torqued up well but I
haven't had a chance to leak check them yet.
