I searched through the posts without finding anyone mentioning my problem so I'm asking for help.
I purchased a new Racor
500 filter from West Marine
yesterday. When I got back to the boat I realized I needed to purchase
the fittings for the inlet and outlet holes to connect my 5/16 fuel
line. Back to WM, they could not find a fitting with the correct thread. I went to NAPA and they ordered fittings for me. This morning, I went to pick them up just to find they would not fit either. But, while waiting on those to come in I looked in WM catalog and on page 583 it shows the part number of the fitting. Back to WM, the part shown in the catalog is not the correct thread. The online instructions state it takes a 3/4 -16 UNC. Went to Home Depot but no luck there. No one I have talked to yet has heard of a UNC thread.
The questions I have are: 1)Why would Racor
use a thread that is so difficult to find when a NPT would work just as well. 2) Does anyone know where I can find the fittings on Sunday?
If I don't get them tomorrow I'll go to a plumbing
supply house on Monday. I'm really surprised the fittings are not readily available given the popularity of the Racor filters.
