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.

    Quality Kit

    This is a very nice quality kit. The lines are perfect length and everything you need is included so you can upgrade your stock lines and get rid of the check valve fittings.

    Great product.

    Great product high quality
    The passenger side line could be a tad bit longer
    Just know getting the fittings into the block may be challenging if you don't remove everything out of the way. I left my turbo on so I had limited space but was still able to get it done.

    7.3 fuel lines

    Posted by Chris on Nov 17th 2021

    Very good quality product my 7.3 had rusted lines replaced with this product my 7.3 has the bigger turbo and has a little more room on passenger side head to get old line and fitting out of head. The smaller turbo motors might have to loosen up the exhaust pipe on turbo to get more room to get to line and fitting.after line installation truck seems more responsive.

    Needed Upgrade

    Really a required upgrade to get rid of the stock factory lines that leak. Superior leak free design is evident. Install is straight forward. Would recommend.

    I bought this and installed it according to DieselTechRon, Ford 7.3 powerstroke fuel leak. It was pretty easy. I used a socket to remove the rear fitting (as suggested by RiffRaff support)

    Quality Kit

    This is an innovative solution to a constant issue on the stock hardlines. This are the perfect length, easy to install and should flow way better. From start to finish the item is a no-brainer to upgrade your 7.3L
