cohline fuel hose failure
Posted: Tue Jul 06, 2021 8:32 pm
After monkeying with the cooling system some more I decided to wake up my tan 86.5 project car from it's winter hibernation. It started up and ran for a bit then I heard liquid. I realized quickly it was fuel and shut things down. Fortunately everything was cold under the hood.
This was the hose (supply?) that runs from near the 14 pin connector up to the hardline to the front damper. Further inspection showed the line was cracking on the outer radius of the bend it makes, and and broken through right at the peak of the bend. I suppose the bend could have been a bit more gradual, but this sure isn't something I expected to happen.
These fuel hoses were put on in summer 2018 after I got the car and did the timing belt job, and the car has run for all of 30 minutes maybe in the past 3 years and driven maybe 100 yards. I put these same fuel lines on my blue car too, so figured I should check over it too. Sure enough there are small cracks starting to form on the outer radius of the bend on that supply line. Not nearly as large as the ones on the tan car, but concerning none the less. I checked the "U" shaped line between the fuel pressure reg and the damper at the rear and found the same small cracks on the outer radius of that bend as well.
After only 3 years and ~5k miles on the blue car I'm not happy with how these held up at all. Could have easily caused a fire. I looked on 928 motorsports' site and it looks like they're selling a different brand of hose now. Wonder if that's why.
