Ian Foster Posted April 16, 2023 Report Share Posted April 16, 2023 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! Ian Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 16, 2023 Report Share Posted April 16, 2023 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 Pete Link to comment Share on other sites More sharing options...
johny Posted April 16, 2023 Report Share Posted April 16, 2023 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.... Link to comment Share on other sites More sharing options...

Seems like everything wants to eat rubber. 8 minutes ago, johny said: needs a known name on it Agreed. I have been even more careful what I selected this time.

Patrick Taylor Posted 14 hours ago Report Share Posted 14 hours ago I have just replaced the hoses on Bertie the Bond (GT4S 1300) with Gates Barricade, so E10 shouldn't be a problem. Tucked away in a dark corner of the boot (partly under the floor) was a piece of ¼" bore hose, push-fitted (no Jubilee clips!) onto the steel fuel line and the tank outlet. Not only that, but it wasn't reinforced -possibly not fuel hose at all? Photo shows it compared to Barricade. So, yes, check those hoses! Link to comment Share on other sites More sharing options...
Steve P Posted 13 hours ago Report Share Posted 13 hours ago Replaced all of mine on the Vitesse a few weeks ago with Gates from the Club Shop,( I need more for my Herald). I had an old braided section from the pressure regulator to the carbs, it was very soft and drawing in air as it took ages to start after a short layup. Anyone know a reliable source now?.
