On my 87 V-20 (5.7), the driver's side tank is out of action, probably due to the selector valve, as the truck will stall when the selector switch is thrown. My question is, how difficult would it be to just remove the tank, selector valve, and disconnect the switch?
-
Not difficult but why not fix it? It's a nice option to have
-
it could very well be the switch in the dash its a $15 fix or it could be the valve. but i would fix it just so you have it and switch tanks every fill up
-
Meh, I sell a ton of valves and switches, and to me it's just another thing to fail. (my last truck, the valve stuck between tanks). I don't need it, and would rather spend the mod bucks elsewhere.

Conversely if one fails you have a backup. If you don't want to fix it right now just leave it

I have a 81 or somewhere in that vintage . It is a yard/woods truck . I might burn a tank of fuel every year . I am thinking that I want to get rid of one tank also . Gas gets old ....

I ~put~ a second tank in my '77. I prefer it, because I live in the toolies, and it's more convenient to fill up whichever tank is empty when I am already ~in~ town. Apparently I empty a tank more frequently than I go to town.

^ 😄
Yeah my truck will never see town again I'm afraid .....

my son disconnected my second tank as somebody had just made one and put it in the did a good job but we were having a problem with keeping gas staying in carb as there was hole and cracks in the line so we just took the y out and use just one tank. problem solved ! have you checked to see if its the fuel line and not the switch /valve that the trouble ?
-
I haven't checked anything yet....
When I bought it, there were two locking gas caps, but only one key, and they were differently keyed. I called the PO, and he told me that it's just on there to plug the hole, that the valve is dead. Logically, when rocking the selector switch on the dash kills the truck, or prevents it from starting, it sounds more like the valve or pump to me. Either way, I live in town, and pass 8 gas stations on my way to work, which is only 13 miles away, so one tank is plenty.
I just don't want to go through what I did with my last 87, when the valve died halfway between tanks. What a diagnostic nightmare for a side of the road repair.
