Anngo Universal Adjustable Fuel Pressure Regulator Kit +100 Psi Pressure Gage AN6 Fitting Connectors Kit Blue & Red

After i installed the regulator, I found out that it wouldn't adjust the the fuel pressure at all. It was running full fuel pump pressure to the carb. I took the regulator top off, and cut a coil and a half off the spring, and drilled the return fitting larger. Works perfect now, steady 7# with adjustability for more or less.

Just like the other reviewer I had to cut the spring and drill the return. But after this it works like a champ.
