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.

Fuel feed lines
Perfect fit, I have bought many things from Riff Raff and will continue to do so.
SS fuel return line
Very high quality, just as advertised or better. Would buy again.
Well worth the price and work to install. Far superior to stock lines, and got rid of all my leaks.
Steel braided fuel lines
Fixed my leaks
Great kit to replace the stock metal lines. Mine were leaking so I went with these upgraded lines. Fit perfect, and look very nice as well. Glad to be leak free.
I was able to install this easily, and it fit like factory.
Riffraff really stepped their game up with professional packaging, I am very impressed! Truck starts faster and runs smoother with these lines installed, and check valves removed. I installed the long one on the passenger side and the short one up and over the fuel bowl, i couldnt make the short line work on the passenger side, other than that, great kit!
As many of the other reviews have said the quality is top notch. A few tips for installation:
To remove passenger head fitting you do not need to remove turbo spider, just remove passenger intercooler pipe, remove the engine lift bracket and you will have plenty of room. Next take a pair of heavy duty cable cutters and cut the old fuel line as close to the fitting as possible, then you can use a 15mm deep well socket ( mine was a 12 point) to slide over the compression fitting AND check valve at the same time and remove the whole assembly at one time. Install new fitting by hand and tighten with appropriate socket, next use 1/4 drive ratchet , 1/4 to 3/8 adapter to a crows foot ( 9/16? Can't remember) to tighten the fuel line to head fitting. The driver head fitting it's best to loosen/ remove the alternator/ power steering pump bracket to gain access. It's only 4 bolts, I was able to just loosen the bracket but depending on what tools you have to get to the head fitting you might need to remove the bracket.
