Square Body Chevy Dual Tanks(1)

[@SOU6900]

I just learned the hard way yesterday to make sure the fuel line you get is rated for fuel. I replaced mine last year both the 1/4 and 5/16 hoses the autoparts guy gave me were fuel rated, but the 3/8 was actually vacuum hose and I never realized it until yesterday when I pulled the driver side tank back off my 86 K2500. I guess the hose lasted just long enough to run for 25 minutes before collapsing and hardening up like that.

Im in the same boat. Previous owner had a fuel pump and tank switch valve put in. Three months later wont start. Gave up on it. Trying to drop the right tank on 89 C3500 Dually. Everything is corroded or shot.

Lol, just got a 1982 c20, the previous owner bypassed it to only one tank works. Now I have to rewire, and run new lines. I hope yous worked out.

Kool i have a question for you!
Im working on a 79 chevy c10 silverado. I dropped both tanks ,on those tanks sending unit have three fuel lines connections, now the guy ordered the news one and got sent 2 sending units the same only with two fuel connections so i looked it up and nowhere to if they work or not,again he ordered two more sending units one has two fuel lines connections and the other has three fuel lines connections will these work or can i use the first ones that were ordered or the second ones ordered?? Fyi this truck is only used for the ranch during hunting season its not for hwy so it only gets used for about 3 or 4 mos out of the yr.

Hey there’s two holes on the bottom I know one of them is the fuel line But then right next to the bottom has another little hole what is that for or what do I connected to because it’s spitting gas out of it

[@stephenlake925]

I just put a brand new valve on mine and I think it's leaking there also...

[@estebanarteaga9035]

CCC...

[@patrickforbes7373]

What colors go where on the plug

[@Freedbyhislove]

Damn…. Mine is leaking into the other tank through the switch valve. How do I bypass the valve entirely?

[@ieatfoodthatisgood]

This is a late response but I had to do this. You'll need to make 2 jump wires. Remove the switch in the dash and plug both in end to end. Crossing them makes it run off the passenger side only and running them not crossed is drivers side. Hope that makes sense although you probably figured it out by now lol
