Re: Restoring Rusty
SAE J30R14 is the new J30R7. It's an updated low pressure fuel hose spec with the lower vapor permeability of J30R9 and better ethanol breakdown resistance in the spec with the lower operating and burst pressures of the J30R7 hose. Most manufacturers already met or exceeded the ethanol resistance spec in their J30R7 offerings but not the vapor permeability ratings.
The stuff you want on the pressure side is still SAE J30R9.
Gates used to have a comparison tool but I can't find it.
