this problem I am having and don't know exactly what is wrong. I installed duel welbro 450 lph to feed -6 feeding line and stock return line. What wire gage should I use ? for now am running gage 12 if i remember right with (40/60 amp) which I guess means 60 amp relay for both pumps. after driving for 2k miles the relay went bad and could not get the pumps to start. today I replaced it with another 60 amp relay. What is the problem here that made it go bad in short time ? I am using 30 amp fuse, the one that has a cylinder shape.
