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.

    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

    Stainless Braided Fuel Lines

    Posted by Cooler on Aug 23rd 2021

    I bought the stainless braided fuel line set for my 7.3l F250. They are good quality. The fitting that goes into the back of the head needs to be about an inch and a half longer. It was extremely difficult to install as is.

    When I first saw these I thought the price was a little high for two lines, but once I got them I see why. They are very nice quality, exact length and fit needed for a seamless install. Also they say USA made right on them. As usual I shouldn't have ever questioned riffraff and their products. Another must do item from these guys.

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

    Installation tips

    Posted by Peter Greenberg on May 19th 2021

    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!
