Thread: Install Question

  1. #1

    Default Install Question

    Hi. I installed new 3/8" mild steel fuel & return lines. The instructions say to use a compression fitting with a barb on the end. Nobody in my area has any. I went online and found a Dorman brass barbed fitting, but they say it will not work on rubber hoses. I understand the Earls hose is rubber. Do you have any idea where I can get the correct fittings? Thanks, Greg.

    The Dorman fittings are designed for the Nylon fuel line, so they have a much sharper bite to hold the hard plastic line. It will cut into the hose eventually. If you have a flare tool, use the adapter for the first step of a double flare and just bubble the line. Not too much that the hose doesn't slide over, but enough that it won't slide off. All the Earl's fittings are is a slight bubble. Be sure to use the correct size EFI clamps and double them on any pressure hose. That's what I did and with the defective pressure regulator cover that caused my fuel pressure to peg a 100 psi gauge, I didn't have any leaks.

    Hi. Thanks for the replies. I have a flaring tool and can flare almost any type of flare. I just didn't know if it was recommended to have the flare on the end of the metal line. Thanks for the links, as any help is appreciated. Greg

    Yes, that's acceptable.
