Fuel line recommendations

    Biting the bullet on the Sniper Quadrajet EFI for the Electra and replacing the entire fuel delivery system from end to end.

    I've checked out the stock fuel line routing and it's all easily accessible and has little exposure to potential road hazard. The question is - what to use for the new lines?

    I'm thinking Earls hose all the way with a small bulkhead bracket at either end of the main fixed run then shorter hoses for tank and regulator/throttle body connections.

    Should I stump up for Ultra-pro for the main run for it's tighter bend radius ability and more rugged sheathing or cheap out and use Vapor Guard all the way - or something in between?

    Cheers
    Bob

    I used stainless for the body line and had Pegasus make all the smaller lines from tank to regulator, regulator to return, regulator to 100 micron filter, filter to body line, body line to EFI (40 micron and small hardlines at the TBs). I used "Earls" for all the fittings.

    No rubber or soft lines anywhere.

    Hey Michael, thanks for the feedback and apologies for taking so long to acknowledge it.

    I decided to go with Earl's Ultrapro with the Black Polyester external sheathing. This is pretty rugged and uses twist on hose ends that only requires basic tools for fitting. It also has a 1" minimum bend radius which means it can handle the twists and turns of the line route.

    The open frame rails on the Electra allow for the main run to be tucked out of harms way. There are only two short sections that have some exposure and I would contend that the rugged sheathing and ability to deform and return to normal if struck make it as or perhaps more resilient than hard line. Its flexibility also allows for body flex, engine movement and expansion/contraction due to temperature changes.

    Cheers
    Bob

    You should be fine with that. :)

    There are pros and cons to both hard and soft lines like you are considering.

    And some of the newer stuff is pretty impressive durability. (and not the same league as the soft/rubber stuff I was referring).

    I may use that on my 1968 that is work in progress.
