J30 is the SAE fuel line standard with R numbers for specific types.
- R7 is emissions hose. Used to be low pressure fuel hose but high vapor permeability likely makes it illegal in California for fuel hose.
- R9 is high pressure low permeability Fuel Injection hose
- R10 is high pressure in tank fuel hose. Submersible fuel line for in tank fuel pumps. Don't use this stuff out of the tank as the jacket isn't compounded for operation in air.
- R14 is low pressure low permeability fuel hose. Likely released to deal with tightened air quality standards.

I hear you brother, I just can't find any J30R9 locally they all point at the R14 just like the dude at the NAPA counter sold me and I told him what I was doing and I wanted the high pressure stuff
