The Waggie has created a bit of a stink after full tank fill. Enough to where the entire garage smells strongly of fuel after two days parked in the garage.
I see where some have replaced metal tanks with poly, any other areas need checked or replaced such a check valves, fill lines, other?
Thanks in advance.

First thing I would check is the vents and the fuel sender. But, you have to drop the tank on a '78 as I recall. I don't think they added the door in the floor until 84ish. Also check the filler tube. Chances are you have a cracked line, or the fuel sender gasket is leaking.
The TSM has a detailed picture of the fuel plumbing. If you don't have the '78 TSM, it would be worthwhile to obtain it. They are available as CD-ROM at RockAuto for under $25.
The '77 and '79 TSMs are available for download here http://oljeep.com/edge_parts_man.html but I would go ahead and obtain the proper year. The emissions and fuel systems were changing rapidly in that era, and owning the proper year manual will be very helpful.

Blockchain the vote.
Just going to second the fuel filler hoses by the rear quarter. When I bought my 77, the vent tube elbows were completely blown, letting all the gas tank vapor into the passenger compartment.
I start what I finish.
