DOUBLE TROUBLE! - 85 C10 5.3 LS SWAP - Plumbing Fuel System With Original DUAL TANKS - UTX

Welcome to Ugly Truck! Today, we're plumbing the fuel system for the 5.3L in the 1985 C10... the hard way. Most people would say to just use one fuel tank, but we're a little obsessive. Since this truck had factory dual fuel tanks, we're determined to keep them both, even if it means twice the clamps and twice the flares! Our fuel pumps are done, so we're running supply, return, and vent lines, as well as mounting the fuel pressure regulator, fuel filter, and return switch valve. Every car and truck is different, but hopefully this gives you some ideas for your own project. And remember, PUT YOUR CLAMPS ON FIRST!

PARTS LIST:
Fuel Pressure Regulator: Fuelab 53501-1 or Holley 12-846
Return switch valve: Standard Motor Products FV1.
Fuel Filter: Wix 33579
Fuel Filter Line/Fitting: Dorman 800-153
3/8 Steel Fuel Line
3/8 Gates Fuel Injection Hose
1/2 PEX clamps
