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.

Not a simple install, but not super difficult either. Fit great, and no more worry of the hard line rub through.

Installation tips
I've always have done all my own work on my 2003 7.3. Riffraff sells only quality parts with fast shipping. I suggest rebuilding your fuel bowl and doing these fuel lines at the same time. I was able to easily attach the lines to the bowl. To install at the back of the head on the passenger side. I used a 1/2" socket to install the head fitting. I bent a open ended 9/16 wrench about 2 inches down. It worked like a champ on tightening the line to the head. On the front driver side install I used a dremel to cut the old line. Then using a 9/16 socket I was able to easily remove the old fittings. 1/2 socket to install the new fitting. Grab that bent wrench and tighten down the front line. I left my fuel bowl loose during this whole process to allow for movement to get the lines to easily go into place. I am no pro... but it all worked great with ni.leaks. hope these tips helps you out!

Quality parts.
I am a repeat customer of RiffRaff Diesel and for good reason. They sell Quality Parts at a great price to fix the very few shortcomings on the 7.3L diesel. My truck now has 224,000 miles on it and still running great.

Installation of Driver Side and Passenger Side
Great product, good service. I needed these lines due to a brake down 500 miles from home. Installed the driver side in 2 hours in RV Park. I am now just getting ready to install the passenger side. Riff Raff Diesel came to the rescue with over night delivery on time next day air.
