Re: Glock's new project: "Fred" w/ 5.3L LS swap info

I would run the relays. Higher PSI means the pump is working harder, drawing more amps and creating more heat.

I would run the stock wiring to the realy and 10 or better from the bat to the relay and then on to the pump. Just my .04 though, some relays and wiring are not worth your truck burning. Watched a friends ranger burn one time b/c he cheaped out on wire for his amp. I learned right then to use the heaviest gauge wire I could find for big amp items.
