Check those fuel hoses

[Ian Foster]

I have just finished changing out my flexible hose elements. I was a bit shocked by the condition, with cracking most noticeable on the outside of bends. There hadn't actually been any obvious leaks and interestingly there is no evidence of cracking internally, but I am sure it would have only been a matter of time.

The old hose is marked W=SAE J30 R9 FUEL INJECTION 7.6mm and was changed in 2016 just prior to the CT RBRR. (sourced from a reputable supplier IRRC). Fuel has almost exclusively been 97-99 octane <5% ethanol.

I have replaced it with Cohline-2240, which interestingly has Kevlar reinforcement. Gates Barricade as sold by the club shop would be suitable alternative.

Beware and check those hoses!

pleased the inner bore seemed sound but this is just more of the fake hose thats been sold and caused much grief  especially them darn  rubber slivers 

interestingly the painted specification has out lasted the rubber,  Im   no expert but that looks like ozone cracking  of the outer sheath

Yes seems like it needs a known name on it and then even if not genuine the real company would be on to the fakers....

Thanks for the comments. Seems like everything wants to eat rubber.

Agreed.

I have been even more careful what I selected this time.
