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.

Awesome lines
Great product, reasonable install, replaced aging stock lines in an unsuccessful attempt at chasing a fuel leak most likely coming from the trash can of a fuel bowl…again…RiffRaff makes some quality parts for the 7.3, now they need to come up with a fuel bowl delete that utilizes the Frx and these braided lines thanks for coming to my Ted talk

Fuel Feed Lines
As I have come to expect from Riffraff, nothing short of a perfect fit, these lines are far superior to OEM steel lines and poorly engineered seals, Again Clay and his engineering performance is a cut above, Im convinced, Riffraff is my soul source for all my 7.3 upgrades and needs, Im going back for Injectors and wiring harness upgrade, and Im sure a slue of other upgrades, Riffraff has my total confidence, Clay knows his stuff, call him and get the straight information on his vast knowledge base. Thanks Clay for all your expert input

SS fuel lines
All around great product over the stock steel lines. Mounted up decent but only suggestion I’d make is the passenger side line should be 2” longer. Other then that another great RIffRaff product

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 service from order to shipping hassle free ....

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
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.
