It has broke twice in my stock fuel module, new hose both times. I thought it was because I over tightened the worm gear hose clamp the first time. The hose had softened, though. I didn't give that much thought, I was sure it was the clamp's fault.
This time I used a crimp-on clamp, and I'm sure it was not too tight.
Also, the hose is obviously soft from absorbing fuel.
I rate this product 4 thumbs down, I definitely won't use it again, and I recommend that nobody else uses it, either.
Sorry, Gates.

 

Maybe it isn't rated for E10. If that is the case, they shouldn't sell it in the Chicago area.

 

Sure it wasn't dayco? lol...I switched to gates hose and have been running it for almost a year now. 6 months of it has been constant exposure to ~E45. If there are any sharp bends in the hose, it will rupture under pressure...even the good stuff.

 

my gates submersible looks a little different. i know i asked for submersible and didnt get it once at the parts house...

 

How many miles before the failures?

I accidentally ran regular fuel hose/vapor/PCV hose, it even said NOT for fuel injection on the side (didn't see it before installing). I used it for about 1000 miles and swapped it out once I realized my mistake. The line was a bit mushier but worked.

I'm using Gates 27093 now, about 4000 miles on it. Gates 27093 - Submersible Fuel Line Hose | O'Reilly Auto Parts

 

That's the stuff. I don't drive much, it lasted about a year.

 

Ls1tech sponsor "shomespeed" has some hose they sell because of gates failures. Got some on the way from them.

 

Got any links? Is it okay for us to link to tech's site?

 

I would contact Gates about this.

 

I'd like to contact their nuts with my boot.
