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

I wish I could say I had a hose leak on a 426 Hemi, but nope, this was on my 1969 Dart with a 273. Sometime in the last couple of years while the car was getting put back together, I installed new reproduction fuel lines at the engine and new hose sections and a filter. This is the old-style that has the fuel filter in-line above the intake. Metal lines with two short rubber sections on either side of a metal filter. Two spring clamps the way Mopar did it 55 years ago. Shoud be the most leak resistant setup possible.

Nope. I went for pizza tonight and on the way back started smelling gas. Inspected things when i arrived home and gas is dripping out of one of the rubber sections. I see green printing on it which tells me it is Gates fuel-injected "rated" hose. I already learned my lesson about using the pieces of line that come with the Taiwan fuel filter in a Wix box. You might as well dump a couple gallons of high-test on the engine and get it over with.

So, where can I order a supply of ethanol-proof 5/16 fuel line? I am not concerned about the cost. Please don't say Napa. That's the same crap any other parts house sells, you're just paying more for it. Also, at this point I'm wondering about those spring clamps. I've heard anecdotal evidence that they don't even clamp as well as the OG clamps. Maybe I'll go to the junkyard and find some on an old car.

Thanks for any legitimate advice.
