I finally decided that I am going to tap the outlet banjo bolt of my fuel filter for the fuel pressure gauge. There does not seem to be enough room to put in a regular 1/8" fitting, so I would like to install a 1/16" NPT Male to 1/8" NPT Female fitting instead. I have located the fitting (Autometer 3280), however, the tap is extremely hard to find.
I know that Holley makes one for their NOS fogger nozzle, but I haven't been able to find someone who has one in stock. Any mail order houses that could get me one quickly would be appreciated.
