[Chicken hawk]

Has anyone reused the high psi fuel line on a gen 3 or did you have to replace it per ford ?

@HKusp What did you do with your recent build? Reuse or new?

I replaced the line. I was going to re-use, because it's a hard line that had 47k miles on it. What, realistically could go bad? But my buddy who does a lot if work on 6.0 diesels said "Replace the line. They call for it to be replaced. You spent all this money on building this engine. Don't go cheap on stupid stuff like this." So I took his advice. I think the line was about $130, if I recall correctly. He's right. They say replace it. Replace it. Don't mess up a build like this. It's just not worth it.

Yeah that is absolutely right. The line I’m looking at is $19 so it would be foolish of me to ignore it. Not sure if this is the same line you were lookin at replacing but here is the pic

Good advice. Very similar to the whole "while you're in there" school of thought.
Do it right the first time and you won't regret it later.
A fuel line, while it seems like it should be reusable, could cause catastrophic damage if it failed.

Plus where it is, if it were to fail, the supercharger has to come off to get to it. Not a terrible procedure, but not something I want to do because of my own stupidity. Been there done that. Don't want to do it again.

I re-used it. no leaks. My car only had maybe 2000 miles on it when I removed the valve covers to do the crank sprocket/OPG's. less is more when torquing these lines down. Use this torque sequence when re-installing it. For sure, if you damage the flare on either end (even a little scratch) replace it.

I appreciate y’all’s advice very much. I too am doing oil pump gears and crank sprocket on this car and only have 5k miles on it. I bought the line and am going to install per work shop manual. Also installing super charger so last thing I want is fuel lines leaking. To much invested lol
