Thread: EFI Fuel Line

  1. #1

    Default EFI Fuel Line

    Ordered my Sniper Kit as well as a Tanks Inc. GPA 2. It'll be on a '74 Dodge Stepside. I’m at the point of determining how much fuel & return line I’m going to need. I plan on using nylon braided long with -6AN fittings. Anyone here recently do a short bed Dodge or maybe a C10?

    There's no reason to run expensive PTFE hose the whole length of the truck. I prefer using inexpensive NiCopp 3/8" hardline for the long runs and using short sections of hose where flexibility is needed. The NiCopp line flares beautifully and mates easily to AN fittings by using a proper flare tool, tube nuts, and AN union fittings. Check out this video:

    I used Earl's Speed Flex -6AN stainless steel braided PTFE hose & Speed Seal fittings (to replace the OEM body supply & return fuel lines) on my last two vehicles. I find it much easier to route and work with under the vehicle, due to its flexibility.
    May God's grace bless you in the Lord Jesus Christ.
