86 Silverado duel tank problems

[blueboy86]

My 86 has duel tanks, right now the fuel selector valve is bypassed and the right tank is removed. I don't drive it very often so i dont care about having two tanks. I would like to know how much gas I have though. Can I hook up the fuel sector valve and only run the fuel hoses from the left tank? And leave the other ports open/ capped off? Is the any other solutions? Anything would help. Thanks. - blueboy

If the switch is good and still wired and switched to the existing tank there should be no reason the fuel gauge shouldn't read

[blueboy86]

Well right now the selector valve is not hooked up. So there is no connection between the sending unit and fuel gauge.

these electric fuel pumps or what?

[blueboy86]

It has a single external fuel pump. Its a 2 barrel carb. The smog bull crap has been unhooked (for the most part). From the left tank I have three fuel hoses. Supply, return, and vapor. Vapor is the only one attached to the charcoal canister.

are the wires still ran to the fuel tank selector switch under the bed?

[blueboy86]

Yes all the wires are ran to the connector. I have a brand new fuel selector valve in the box. Like I said the valve is bypassed. So the wires are disconnected under the bed.

[blueboy86]

So basically this is my thinking. I cap off the ports for the right tank on the selector valve. Hook up the fuel lines for the left tank and mount the valve under the bed. And obviously keep the switch on the left tank. This way my gas gauge works and I can still put the other tank in when I want.

Perfect solution IMO

Thanks. I just didn't know if that work work lol.

if your not planing on using dual tanks i would leave the fuel lines alone and figure out which wire go to the gauge (should only be one wire on + ground the sending unit) then figure out what wire goes to the gauge and make a good connection and be done. i wouldnt worry about rigging up a selector valve if youre not using dual tanks. just one more thing to go wrong

[VileZambonie]

Just pop the pink wire with the rubber cap off and move it directly to the good tank sending unit. You can simply bypass the valve altogether as it can easily fail on you in the condition you have left it.

BTW it's dual tanks not duel tanks. This is what duel tanks look like

Lmao

[timthescarrd]

Vile, wouldn't that be dual duel tanks?

dual dueling tanks
