I have the fuel pump issue on my truck, I have a blue holley pump and it has overheated my relay twice now. Problem is Blue pump pushes 12? psi, red pump pushes 6 psi. Fix, put the red pump spring in the blue pump, then pump doesn't overheat and destroy itself. Problem is spring is $12 +shipping, so I haven't enjoyed the thought of a $20 spring, when a new mechanical pump is $15, lol... Any tricks for this would help.
