So far, the only source I have found for a pre-bent steel fuel line is LMC.
They are verifying that their line can be used with my dual tank setup.
Not too expensive itself, but shipping is high.. The longest 3/8" steel tube I have found is 6' and that isn't long enough..... Any suggestions?
Not sure if it's been mentioned, but try inlinetube. Know they do a lot with brake lines and some fuel, trans etc.

But yeah, check rubber hoses first and see if they're leaking and the fuel isn't travelling down the line and collecting there and subsequently dripping.

You can always cut the line, flare both sides and place a union in it. And most reputable local parts stores, not the big box ones, will have lengths longer than 6'.

What is wrong with all you guys??????? Go to the parts store (if you can find one still open ) and get a "coil" 25 feet of NIcoop "nickel copper" tubing and bend up your own. it comes in all sizes, will NEVER rust and can be bent by hand! All plusses!! Last coil I bought was ~ $25.00

They didn't engineer it for our convenience. It was engineered for speedy and cheap. Rather than waiting on line I'd go to the parts store and buy a 3 foot and a 4 foot and join them,2 4 foots a three foot and a 5 foot,you get the idea.
