hi guys, after melting a few elctrodes on the plugs at the last race using some NOS, I realized it's time to add an additional fuel pump. I run a Mallory 140 and I am adding a seond one, one pump will be dedicated to the motor and one pump with a toggle switch will be turned on when I run the nitrious.
I have a lot of fuel line as well as a return line. here is my question : The return line is the same diameter as my fuel line, I have been told that the return must be larger than the fuel line. How crucial is that and can I get away with using the line I have rather than purchasing larger line ?
