EFI Fuel System

have to run a reg with the pressure at 43-45 . use alum. racing fittings on some , and fuel inj. hose supplied by fast that is legal .< can be bought from jegs and summit too...

See the 5/16 nipple? That's the return.
The nipple doesn't have a fitting.. not sure if just clamping a hose onto it si good measure or not. Whats your setup?
