Had a lot of free time lately and decided to find and fix the leak ive had on my 2001 7.3. Decided to replace the fuel lines and entire fuel bowl as well and found these with a lot of positive reviews. Im not mechanic by no means, more of a YouTube mechanic, but after watcher several videos on YouTube I decided to tackle this project. Along with the instructions and my videos removing was not a hassle. The only issue I had was the passenger line on the back of the head. It was tricky but I was cleaning up the turbo spider and adding more riffraff mods so I removed it and the cold side intercooler pipe so after adjusting myself I was able to reach the port to remove it with a 9/16. Installation to the passenger head was easy-ish as well with the turbo spider removed. The driver side line was easy well with the ICP removed (another part i decided to replace) and the use of a crow foot or flat wrench. Since I was replacing the fuel bowl with a new one, running the lines and screwing them in were easier for me then having the fuel bowl sit in truck. While the fuel bowl was out I could adjust the threaded ports easier before screwing on the lines themselves. After adjustment was made I started to hand tighten the actual lines to these ports all while the bowl was still free. Once I liked the way the lines looked and didnt have any pinches or awkward direction of lines and how fuel was going to run, I tightened the fuel bowl in the truck then the lines. No leaks luckily and the engine valley looks cleaner. Definitely helps to see if anything leaks when you have a clear view of your valley.

Ease of installation an fits absolutely flawless just enough in length an flexible so can be easily routed, fast shipping also

I’ve been working on upgrading the stock fuel system in preparation for larger injectors, these lines fit the bill. Gets rid of the restrictive check valve and leak prone stock connections all in one shot. It is nice that they also include high quality thread sealant with the lines. As a word of caution to those not familiar, only apply thread sealant to the pipe thread ends of the fittings.

Kit came with everything needed to do away with the factory lines. This company is amazing to deal with. They have done their research and made a great product with amazing instructions.

Great product, exactly as described on the website. Was not thrilled with the instructions, they were detailed until the part where the fuel line needed to be connected to the passenger side of the head (toward the firewall). This part needs much more detail. It is the hardest part of the job.

First of all, this was tough to install. The fitting on the back of the passenger head has to be done by feel and the smaller your hands are, the better. The driver side is easier but requires the partial removal of the alternator bracket to access the fitting. But the quality of the hoses and connections are top notch. I had the common fuel leak at the passenger side tubing clamp so had to do something. This kit was the best I saw and it installed with no leaks. I'm totally happy with it.

Replaced these fuel lines a little late !
Cost me 900.00 to get towed back home.
These new ones went on without any problems, except for the pass. side rear one which wasn't the fuel lines faults.. just hard to get at ! No leaks and back on the road again.
Thinking of changing out the oil lines now.

The new hoses are far better then stock and will flow better with less restriction.

Good idea, innovative solution to the factory lines that leak.
