Will a GSL tank from an 83 fit into an 85 GS?
I have an 85 gs as my dd beater and fuel gauge doesn't work, so I know I can go 300 miles every fill up so I fill up- about a week ago I filled up and found a hole now so it leaks for about the first 50 miles. Bought a new (used) tank off a member and tried to install it today with no luck it will not go in- am I doing somethng wrong or are the tanks just different because they look almost identical besides the fact the 85 has a removable sending unit and the 83 does not-
I searched and found nothing any help?

What do you mean by will not fit?
The '82 Fuel tank I had is almost the same as the GSL-SE one I am using, the only difference is as you mentioned a removable sending unit.
Are you sure that you're using one from an 83? the SA use a different gas tank because they used a full sized spare if I remember correctly.

I cant see any physical difference that would prevent them from being installed

I was not able to put an 83 tank on my old 84 GS. The tanks are slightly different. I agree with Dave on the years that are interchangeable. The top flat area where the fuel and vent lines are is wider on the 83. The 84-85 tanks are slightly taller and the fuel pickup line plate adds another 1" or so.

I have not personally tried this swap but others have stated that all 81-85 models will interchange.

All fuel sender units are removable.
You can remove the line assembly(Different part and location) on the SE so you can replace the sock filter inside.

if u have a welder fill the tank with water and weld or braze the leak just put some heat in when u emptey the water and let it sit for a day or two (slosh the heat around)

Interesting. I had the same problem that 12arotary has. I couldn't get the tank to go up all the way. The top hit the body and the straps weren't even close to being long enough. If the tanks won't interchange there would have to be some difference in the 84-85 spare tire well. I have 84 and 83 parts cars. I'll take some measurements and see if I can find a difference.

Problem solved- 83 tanks don't fit in 85's stock-ly they are different-
welding is out of the question due to the fact there are like 3 pin holes on an
area thats super rusty so I would have to remove a large portion of the top and replace it so i'd rather just replace the tank, also the walls on the inside are pealing off so no matter how many times I power wash it,or use rocks and kerosene- everything- it just gets dirty again- so i'll try to fine another thanks for the info all
Dave's response of this is correct-
tanks are fitted to the following years:
79-80
81-83
84-85

I measured the distance from the left inside metal wall to the left edge of the spare tire depression, directly below the rear left speaker. 83 GSL was 15". 84 GSLSE was 14". I'll take some more measurements when I have time, but It appears the two cars I have are different.

Silly question but are you loosening the front (forward) long tank strap bolts about 3 inches prior to installation or are you just installing with only the Rear short strap bolts?
I took me 3 tries to figure out that the front bolts are there to provide slack in installation of the tank. I was freaking thinking that the 85' -SE tank was different than the 83' GSL tank I was replacing for Ron.
I works just fine, the sender on the GSL-SE tank is 3 prong, 83' sender is 2 prong connector.

and you can get the three prong to work fine with a two prong sender

I believe the 81-83 tanks have a slightly wider flat area on top. That would let 84-85 tanks fit into earlier models since those tanks are slightly smaller. The problem comes when you try to bolt the wider top of the early models into the smaller area on the 84-85 bodies.

Answer is it doesn't without some kind of modification-
it should work the other way around
