Riffraff Diesel Fuel 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. 

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. 

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.

    Huge improvement over oem. Threw these on when installing some new injectors and the truck runs out great now.

    Great quality kit, nice to see usa made stuff. Deletes the check valves in the heads and replaces your junk stock lines all at once for a low price. I did the spring kit at the same time from you guys. No leaks, and it looks great.

    What better way to pass the time in Rona Quarantine than to work on the truck? Had a leaking passenger side fuel line on my 2000 and saw these so decided it was time to upgrade. What a difference in quality, and knowing I don't have to do this job again. Added plus, with the included adapters you get rid of the check valves so you get even more fuel flow. Perfect fit, well made kit.

    Great Fuel Lines

    Replaced my oem hard lines with these after installing a T4 turbo mount. Original installation was for more clearance of the passenger side line against the pedestal, but these lines are far superior to oem. Very high durability and a clean look with the black coating protecting from abrasion. All fittings are very high quality and leak free. Excellent product at a good price! Installed with a FRX kit to make it all match! As stated it’s a tight fit getting the D side fitting in there, just remove the alternator bracket bolts and your serp belt to pull it forward and out of the way.

    Great product

    I really like these fuel lines. Makes re installing the fuel bowl a little easier. Fit is perfect. Quality is excellent. On the van the driver side is a bit difficult to install. You will need to loosen and move the AC mounting tower to get to it but worth the effort.

    I would recommend this kit to everyone. Easy install, and really how it should have been done from the factory. Perfect fit, well made in the USA, just get it now before your stock lines leak like mine did.
