85 K20 Dual Fuel Tank 16 to 20 gallon conversion? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It's time to work on my 85 K20 fuel tanks. It has duel 16 gallon tanks and one of them is leaking due to a rusted frame bracket and a hole in the bottom while the drivers side will not supply fuel (maybe an electrical problem as I have already replaced the dash switch and selector valve.

I plan on pulling the bed to trouble shoot the drivers side issues and I might as well convert to 20 gallon tanks while I'm at it.

Will the 20 gallon tanks swap in easy enough? Any tricks you could share?
