Did the VR6 wagons have a smaller tank than the diesel wagon?
Vortex is where I used to find a lot of local gasser owners but it’s been dead for a few years now. And yes the fuel prices are
… not as bad as Europe but not all that favorableThis is what I understood:
The sedan has the 18.5 gallon tank.
The wagon has the 100 Liter (26.4 gallons) tank.
The sedan has the 18.5 gallon tank.

I disagree...the wagons used the same size tank regardless of fuel, the difference between a VR6 wagon tank and a diesel wagon tank is the hole for the fuel pump on VR6 cars vs the sender on a TDI car. Well and the inlet restrictor too is different on VR cars (unleaded fuel).
The tank from the 16v B3 wagon is identical to the B4 TDI wagon tank except for fuel restrictor, and somewhere I have a pic comparing the two. And I found them:
This is comparing (on the left) a 1990 B3V 2.0L 16v gas fuel tank with a 1996 B4V TDI fuel tank, they are the same tank, which is actually kind of nice however I'd already bought the TDI tank so oh well. The only difference is the fuel restrictor in the neck used for unleaded fuel, otherwise I see no difference in them. The B4V VR6 fuel tank is the same size as both these but has a much larger opening for the drop in fuel pump / sender unit, like that from a Mk3 gasoline powered car.

EDIT : Personally if I was in a position to get it I would...just because a TDI tank from a wagon is good to have just in case you want to convert some dead VR6 wagon over to diesel.
I wasn't aware that it was technically classified as a 26.4 gallon tank, VW never says that in the owners manual to the best of my knowledge, at least not in the 1990 owners manual. And online it says all the B4 cars had the same size tanks, 18.5 gallon.

First off, welcome back….
Not looking to go too far with this, but I remembered the gas wagon owners wanting this tank for the reason I mentioned. I never had a need to compare anything, just info I gleaned from the internet. Maybe it was just an internet myth that grew from the results of venting and it just spread.
The tank to the right does appear to be a bit taller, and the shape angle of the filler next/expansion chamber looks different, too.

Thanks Todd
Yeah, it might appear that there are differences in the tank but in actuality there's nothing to that, and the angle of the photograph isn't perfect so there is that too. The neck looks taller because it still has the rubber boot on it that I took off the original 16v Tank. The alleged differences you mention would not amount to much anyway, certainly not in capacity, and it would be very odd for VW to increase production costs unnecessarily just for a minor difference in tank size.
I always thought that since all the info from VW said 18.5 and we knew that applied to sedan fuel tanks, that they just committed an error in the original docs when the wrote up the manuals etc. The sedan tank is quite a bit smaller, more akin to the Mk3 fuel tanks.
The gasoline wagon tanks are for all intents and purposes the same size as the TDI, it's just the opening that's different for VR. Here's a photo of the VR6 wagon tank that shows how much larger the fuel pump / sender opening is on VR models. The space for the larger opening is cleared away even on TDI cars if you look at the mold marks on the TDI tank above. I can't imagine why a VR owner would want a TDI (or 16V) tank which would render their fuel pump / sender unusable though.
I think this all came about out of the conversions forums back when there were enough of these to convert and people were doing that still.
