Title: Hard line wear?
Post by: wolf_walker on May 23, 2013, 05:13:10 pm
Anyone ever seen wear on the ID of the injector hard lines? Pump and injector side, looks vaguely like a torx socket.
Is not any sort of deposit.

These lines probably have a half mil on em if they are the set I think they are.
Wonder if that much fuel wore em?

Maybe I have been lucky, but I have never had an issue with one hard line on the handfull of cars I have had over the past few years as daily drivers.  I just make sure to release all hard lines when timing and use the vibration dampners then tighten everything down.

I once had a pinhole on one line... damn near invisible, but it was spraying aerosol diesel all over the engine bay. Seemed to be a void, the rest of the line was fine, so I flowed some bronze onto it and put it back in service.

Yeah I've seen a few leak/crack but never noticed anything odd on the inlet/outlet.
Weird..

I have had some crack over the years and the lines leak at the fittings from wear and age.

Prothe has a set for $14 that I have been running for 2 years with no issues so far.

Might just buy some cheap as they are.

I would advise against going cheap, I bought a cheap chinese one from ebay to replace a an old cracked original one. The new one cracked a week later in a different spot, with the anti-vib clips on. So I ponied up and bought a new set made in germany I think, and they've got probably 10k on them so far.

I second the Prothe lines. Mine are still going strong after 200 k.

Not that I don't believe they could be crap, but I'd think it'd be hard at this late date to not be able to make a steel
line like that.

That's what I thought too when I bought it, how could they screw it up?

EAsy, you use a cheaper materiel til somebody calls you on it.
Or there is a misunderstanding of a blueprint.... we got a couple  prototype bikes from a Taiwanese factory, and the steel one rode well.  the aluminum one in high gear, the crankset would bend 3-4" side to side opposite your downward pedal stroke.  After a few emails, we fond out both bikes had been assembled using the  steel tubing thickness spec , so it was about 1/3 as strong as it should have been.

I see this very often. Probably 75% of the lines I see have some level of wear. I suspect it's either erosion or cavitation from air in the fuel

That's all I could think of. Ever bothered to clean em up?

I don't see any advantage to trying to clean them up. It's probably all the way through the lines.

Are the Prothe set plated or do they rust?
