    Pretty ingenious method I found tonight while doing some research on Nylon fuel lines.
    Budget fuel line option raiding the yards, and doing this saves some $$$LOOT!!!$$$
    All new cars have this type of fuel line and fittings I've been told.

    Saves you the $100 on the Dorman Nylon compression tool.
    However, I'm not sure how it will work out with 90* fittings.

    The only thing I would be concerned about is the aggressive grooves inside
    the tubing holder making those marks on the outside of the plastic. Maybe
    if the tool was modified to remove the grooves by drilling it out first? Also I
    had read those soaking the tubing end in hot water for 20 seconds eases
    the installation process. I dont recall a lubricant though.

    could pad the block/vice with a piece of innertube and it might help keep it from slipping through also.

    I also agree with the hot water soak to soften the tubing.

    I would like to see the pressure test as well. Also, I have seen two ply type hose and what happens is the barb forces the inside ply apart from the outer one. I will admit, doint this job sucks!

    hi guys,
    FYI also the Dorman tool (that I have and I use sometimes in my shop) leave the marking outside the tubing, as you say in post #2.
    I think it isn't an issue.

    This is unbeatable.....
    You can plumb your entire system for under $100 with NEW OEM lines.

    You get packs of 5 fittings each for $12.99 or 2 for $6.99
    I just spoke with Dorman via chat to confirm this is correct.
    Any part #'s that end in ".5" like 800-082.5 = Quantity of 5
    So Advanced is the best place to get all of these parts with the $20 off $50 coupons.

    Example $12.99 > DORMAN 800-082.5 3/8 to 3/8 straight QTY = 5
