Modern Replacement Fuel Hose Available Locally

[MV8]

Most everybody is stuck with E10 ethanol blend gasoline at the pump. The old spec hoses (SAE30 R6, R7 and for efi feed, R9) work but have a short life, becoming hard and cracking.

Gates "Barricade" hose (R14 spec) is stocked and sold by the foot at O'Reilly's Auto Parts. The part number for 5/16" ID hose for carburetted applications is 27340 and is about $10/foot. It has a liner but looks identical to the traditional hose with a similar outside diameter so the clamps can be reused. Also, if you have much more than two feet of rubber hose in the entire fuel system, you might consider fitting more hard line.
