Fuel tank interchange information
 

Ladies and gentlemen will the gas tank from an 1985 fit in my 1983??

Thanks.

There is a low fuel light in the 84-85's that are not in the earlier 7's.

Yes.
Just use the sending unit from yours.

Thanks alot.:)

OK complete turn of the clock. Will a tank from an 1981 fit into my 1983???

Thanks guys....:confused:

Yes

Here are pictures of 83 GSL and 84 GSLSE tanks.

81-83 are the same tank, so yes

Here's an '81 tank I pulled the other day.

It looks like the '81 tank has an extra breather on it that the '83 car doesn't use. It can be capped.

Similar question:
Will an 84-85 pickup fit in an 81-83 tank?

Along the same lines, I beseech thee for answers. Are there new or aftermarket tanks, pick up AND fuel levels senders for S3s?

84-85 do all models have the same tanks? look like they do but is there a real difference

I have a bolt-on feed and return line section that came in the trunk area of my '83, and had assumed that it fit the tank in the car until now. I noticed the lines were smaller than the '84 SE tank lines that I've got, so I'm assuming that the bolt-in section is for an '84-'85 model with a 12a. Any comments? Doc-(or anybody that knows for sure)I'm swapping in the complete dash and instrument cluster from the '84 SE into my '83 GS, what will it take to get the "low fuel" light to operate properly with my swap? Thanks for the info, guys...

inuissus_cendi, nope.

wotnartd, check Mazdatrix. The prices for a new tank are sky-high. A new S2 pickup is only $72. A new S3 pickup is over a hundred because it included the low fuel light sender.

bugman1973, 'all 84-85 tanks are the same except for one difference. The GSL-SE tank has a sump cup and the 12A tank does not. Also the bolt-in pickup tube thing has larger tubes on the GSL-SE.

rxforspeed, you assumed correctly. It is from a 12A model. I think Steve has some information about the low fuel light.

Jeff the moola is in transit. Thanks you saved my restoration project..:)

For everyone. The replacement 84-85 Fuel tanks are the same whether for the Se or the carburetor version. The originals were different.

Thanks Jeff. Which Steve are you referring to? I'm still new enough to not know many of you guys by name yet...

Awesome. :)

rxforspeed, I'm refering to steve84GS TII. He once mentioned the low fuel light so he'd probably know a few things about it. Wouldn't hurt to ask.

Thanks again Jeff...
