How hard is it to convert from a dual fuel tank, to a single. We've owned this truck since new, and I don't remember the fuel tank switch valve ever working. Is it a big deal?

New hoses to bypass selector valve and wire the gauge wire to that tank only. There's wire diagrams on our site somewhere and that should help wire the gauge up,
unless you just leave it alone and let it work how it's been working. Either way the selector valve should be bypassed to eliminate possible leaks in the future.

It's dual, the spelling police are going to get you! We have them on here.

Sounds pretty straight forward. Thanks

Movie is called Duel, 1971 movie. Most people never heard of it
Is this the movie with the semi truck chasing the guy in the dart ? If yes I've seen it a long time ago.

Gotta ask... Why would you even worry about removing the 'bad' tank from the system if it hasn't caused issues in 40+ years?

Sounds like work that doesn't need to be done.

^Was gonna say the same. Seems like a leave it be or fix it right kinda thing.
Dunno how much OP plans on driving the truck but if it’s a knock around pasture wagon, leave it on one tank. If using it regularly and driving any real distances, double the fuel capacity is nice.
Regardless, you’re gonna want to get to the top of the tank and just replace the hoses/re route the 3 lines from there. At that point it’s easier with the bed off and with the bed off, it’s pretty inviting to fix it right the first time IMO. Thinking more long term.
Bypassing the selector valve for the gauge should also be done if you’re truly going to one tank permanently.
And if this is just. Stop gap then why spend any time at all if it’s been fine for 30 years.
