Riffraff Diesel Fuel Feed Line SS Braided Hose Kit - 7.3L 99-03

Our new feed line kit utilizes Eaton Aeroquip® 304 Stainless Steel Braided lines covered with a groundbreaking protective layer of HYTREL® from DuPont to replace your worn and restrictive OEM hard lines that run from the fuel bowl to the driver and passenger side heads. This allows you to move from the problematic stock Vibra-Loc® sleeves to a leak proof JIC adapter for long term security against the possibility of a leak. 

Our SS Braided Fuel Line Kit also solves the issue of pedestal interference on the OEM passenger side metal hardline when you convert to a T4 Turbo kit. This kit covers the fuel lines from your 1999-2003 7.3L Fuel Bowl to the fuel rail in the cylinder heads. 

Made in the USA

Installation Note - Do Not over-tighten the 90º elbow that is installed into the fuel bowl. It is a tapered thread, and if over tightened can crack the fuel bowl.

    Great product, exactly as described on the website. Was not thrilled with the instructions, they were detailed until the part where the fuel line needed to be connected to the passenger side of the head (toward the firewall). This part needs much more detail. It is the hardest part of the job.

    Fuel line replacement kit

    First of all, this was tough to install. The fitting on the back of the passenger head has to be done by feel and the smaller your hands are, the better. The driver side is easier but requires the partial removal of the alternator bracket to access the fitting. But the quality of the hoses and connections are top notch. I had the common fuel leak at the passenger side tubing clamp so had to do something. This kit was the best I saw and it installed with no leaks. I'm totally happy with it.

    1999 f350 fuel lines

    Replaced these fuel lines a little late !
    Cost me 900.00 to get towed back home.
    These new ones went on without any problems, except for the pass. side rear one which wasn't the fuel lines faults.. just hard to get at ! No leaks and back on the road again.
    Thinking of changing out the oil lines now.

    The new hoses are far better then stock and will flow better with less restriction.

    Quality line kit

    Posted by James on Aug 12th 2020

    Install was a 2/5 just takes a little time to fit my fat hands in for the head adapters. Nice quality lines, nice stainless hardware. Recommended over the restrictive stock tube for sure.

    SS fuel line kit

    Posted by William on Aug 10th 2020

    Really good product with great quality parts. The only trouble I had was that I couldn’t find the instructions to install the parts. Tip is you can take a couple of extensions with 13mm or 9/16 deep socket go behind the turbo remove the old fittings from the passenger head and tighten the new fitting when installed can’t remember if the new fittings are the same socket size as the old fitting. To tighten the passenger fuel line I used a slightly Bent 9/16 combination wrench with the down pipe installed it’s a tight squeeze but made it work. a stubby 9/16 would be best but didn’t have one on hand.

    Really good product with great quality parts. The only trouble I had was that I couldn’t find the instructions for the install. Tip is that you can take a couple extensions with I believe a 9/16 or 13mm deep socket go behind the turbo to the rear Passenger head to remove the old fitting and tighten the new fitting when installed. A slightly bent 9/16 combination wrench helped with the install of the fuel line on the passenger side with the down pipe installed.
