Re: 1971 5.3/4L60E first time swap

Here's my plan for the fuel system, ordered a 1972 C10 sending Unit from rockauto, with 3/8 feed and 5/16 vent (going to be my Return)

Ordered 15 feet of stainless steel braided fuel line from Jegs.

Went with walboro 255 with a pre and post filter, and just gonna run 5/16 EFI rated fuel line back to the tank

trying to decide on AN fittings was not easy, going to be my first time messing with them, heres a diagram i drew up to get my mind around what i would need lol

Edit: in my drawing i show a 10 micron fuel filter as a pre, I realized my error after the fact that i ordered it. i ordered a 100 micron filter from amazon (why are the larger partical filters so dang expensive?!?!)
