OK, here it is. I have an 85 gsl running a 76 large streetported 13-B/GSL-SE rotors, 48 ida blah blah blah. I bought the ZEX NOS brand, and a 5gal fuel cel but undecided on which fuel pump to use. I spent several hours reading prior posts on NOS install but no one mentioned the fuel pump they are use. Im kinda leaning towards the mercedes benz fuel injection fuel pump. Any suggestions on the f/p and regulator?
