NJ-2-20-F Universal filler neck
I have a 1970 GTO with a stock replacement tank (Spectra GM34M). I hate having to babysit the fuel nozzle when filling at the pump. Spill-overs are really annoying. Since it wasn't the original tank, I had no issues with lopping off the end of the fill tube just shy of the beginning of the internal splash shield. I did trim off the swaged end of the replacement neck to facilitate a butt style connection. I then used a 7-inch piece of coupler hose and secured this replacement neck to it with 4 worm clamps. Now I can fuel with confidence and have the pump kick off when full just like my regular ride. Thanks guys!
