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.

    This hose kit is perfect! Direct replacement for the OEM steel lines that are famous for wearing and leaking at the clamp on the passenger side and less often, on the driver side. Mine was the driver side that was leaking. That passenger side head fitting was a major PITA but doable with patience, about 24 inches of extensions, a 9/16 crow foot, 9/16 open end wrench, and a 12 pack of beer.

    not the easiest part to fit in and secure but still better than steel lines.

    Nice quality part

    My OEM hard lines leaked from vibrating against the passenger head. This kit reroutes the lines nicely. Installation was simple, directions are straight forward.

    Install was straight forward and at a great price. I'm happy to be free of the hard lines I've had to replace over the years. Thank you Riffraff for a great kit!

    2000 7.3 SD fuel return lines

    Posted by RonJDio on Jun 9th 2023

    Great product. At 400,000 miles, suffered the fuel line retention bracket wear through, prompting the purchase of these lines. A bit difficult to install, but loved the outcome.
