Vent line fuel tank?

Put a check valve on there. Should be able to use the same style that is used on your axles. It'll let the gas/air escape but won't let anything in.
If you plan on wheeling, I would not want the vent line outlet to be low, nor to have any low spots in it that could collect fuel.
Even on logging roads, with a full-ish tank, fuel gets up to the level of the gas cap, at least in my experience.
I just did this on mine (it really makes sense to run charcoal canister when possible I now know) and I used 1/4" hose which I secured to the fuel fill "neck", then routed up above the fill neck between the two sheet metal panels of the body. Yours will be setup differently as you have no fuel door, access to that location is easy on the later trucks. My buddy ran his vent hose behind the tail light, as there is quite a bit of space in there.
Buddy suggested using one of the inline fuel filters (as used on small gas engines) but I didn't like the idea of the end being "open", as I've had wasps plug open vent hoses up before.
Edit: BTW, I'd like to gloat a bit. Getting rid of the dual exhaust was one of the best things I've done with this truck. I can remove all the fuel line connections (EFI too) by sitting on the ground, to the passenger side of the driveshaft. I can clearly see, and easily reach, all the hose connections, either threaded or hose clamp. Not easy, but easier than trying to disconnect them while you try and balance/remove the tank without breaking anything.
