All right, is there any good 5/16 fuel line anywhere now?

I'm in agreement regarding fuel hose and clamps available these days but the link for aircraft spruce is not for fuel hose. Went to website and found specific hose for fuel.

Parker Super-Flex 397 Series Fuel Line Hose | Aircraft Spruce
MIL6000 hose can be used for fuel (100LL AVgas) MIL-H-6000 can withstand both high and low temperatures (from -40° to 250°F). It meets or exceeds tough U.S. military specifications in handling the punishing effects of fuel, oil, alcohol, coolant, and water. MIL-H-6000 features an oil resistant tube and is reinforced with a high strength mildew resistant yarn. The seamless compounded inner tube with reinforcement and a protective outer coating prevents tears, sprays and leaks.
