Hardline fuel fittings to nylon hose. Where to buy that don't require double flares?

I have to fix a crack in my fuel line right before the fuel filter and don't want to deal with double flaring the hardline under the truck (it's hard enough not upside-down, against a framerail, and in low light)My friend was supposed to order me the fittings but didn't, nor did he tell me the brand, part numbers or where he was going to order.Can you tell me who makes flareless hardline fitting to put on my 5/16 hardline to connect my 5/16 nylon fuel line? Someone here mentioned Swagelok, but I couldn't find 5/16 hardline to flex...Thanks....

i used swageloks on my fuel lines. a regular swagelock union will bite into hardline or nylon line as long as the o.d. is the correct size.

Where do you order then from?

Damn, nobody has anymore suggestions?
