Hello everyone. I am new here. I am looking for a gas tank for my 68 88. Please any help greatly appreciated.

 

Welcome! Not sure why you are replacing your tank, but no reproduction tanks are made for these cars. Often tanks can be boiled out (cleaned) and small leaks repaired. I haven’t had to do this in years but I had a local radiator shop clean mine for me. Hope this helps, Dave

 

As Dave said, nobody makes reproduction fuel tanks for your car. If your tank is in decent shape you can restore it with a DIY kit.

If it's further gone you can have a radiator shop hot tank it and repair the holes.

 

I have the same problem with my 72 D88, A Buick Century form same year kinda fits, the indents for the mounting is about a 3/4 in. off.
It was a GM61A, I sent it back, would have had to modify mounts, I am fixing old tank

 

I replaced by 1969 Delta 88 gas tank with a Spectra Brand GM61A. Its listed for a Buick but fits my car well.

 

Can also suggest you check classic car junkyards for donors in places like DVAP Arizona. I’ve had good luck at Turner’s Auto Salvage in CA, Hess Brothers in CA, and French Lake Auto Parts near Minneapolis MN.

From Turners, I carried a wildly chemical smelly empty 1966 Olds 98 gas tank for 4 hours or so with windows down, even though it was slightly dented. It’s still in my attic, not sure if I’ll ever use it, but it’s insurance for $200 bucks or so. Will never forget buzzing up I99 at 70 mph with windows down on a 90F day just to keep the venting gas tank from overwhelming my lungs.

Probably should have rented a truck….
