Fuel line leak repaired!

[rt_hawk]

Had my passenger side fuel line start leaking. For the same cost as 2 new fuel lines from ford, $100, I replaced it with -6an line and fittings. Truck starts really fast and it idles a lot smoother without the check valves...just FYI guys...

Looks pretty nice! Where'd you get them? Are they bigger than stock?

Thanks, I got everything from summit racing like 2 years ago for a different project and this was the extra stuff. But when this leak sprung up I figured it was a good time to use it. And it is bigger than stock. Stock is like .25" or a tad smaller, this is 3/8". All the fittings are 1/8th" npt to -6an. I was really surprised to see how small the stock fittings in the head are...diameter of fishing line almost. Hard to imagine they didn't restrict fuel. Oh and I used high temp thread sealant from permatex on the heads and bowl.

Sold! lol do you know how long they are by chance or are you going to make me go out and measure?

[rt_hawk]

Lol, I think they are both 24 inches. But I had a lot extra for the drivers side hose, you can use a shorter one there. I'd definitely measure yourself to make sure. Also one side is strait and the other has a 45.

Oops, the ones I used are both 30". But yeah the drivers side hose can be quite a bit shorter. Passenger side is perfect though. Here ya go...Fragola Performance Systems 375030 - Fragola Performance Systems P.T.F.E Hose Assemblies - SummitRacingEquipment.com

Perfect. You gotta hold my hand through these things sometimes.

Thanks!

Holding hands I can manage, just don't make me wipe butts. Glad I can help.

Here is a picture of the stock fittings in the head vs. new fittings. The stock fitting has a opening about the size of fishing line, you can kind of see that in the picture...but the aeroquip (blue) fitting is waaaay bigger. Just a guess but I'd say the aeroquip looks about 10 to 20 times larger than stock. Although the stock one may open up under pressure...still, can't help, and my truck has had no issues for 10k miles now. No more lope at idle, smoother idle, faster starts and just a happier smoother running 7.3!

Nice upgrade! I am going to add it to my mod list. What are the stock check valves in there for in the first place?
