fuel hose deterioration
Posted: Tue Jun 11, 2019 5:38 pm
HI Folks
Gave the +2 it annual service to day and am getting a bit concerned about the state of the hoses use for the fuel injection ( car has a Emerald system wasted spark, with jenny throttle bodies and ford 36 tooth trigger wheel). The hoses are only around 4 years old. I have attached a picture of a section of hose that is in good order with a clear description of what its spec is. The OD of the hose is 14.5mm. I have looked for a similar hose on the web and I found one with a part number incorporating R7 rather than R10. Anyone know what this means? Could this cracking be related the use of modern fuel with added bio fuel ( usually fill up with 97 grade at local BP garage.)
I have attached a picture of the cracking. from what I can tell the bend radius of the hose seems with spec and I used springs to keep it in place and contain it so it does not put any stress of the fuel rail fittings.
Any opinions or advice would be helpful
regards
Bob
