I've got a 1990 Olds Custom Cruiser I bought for $300.
Unfortunately, it leaks gas from both sides of the tank and is beyond repair.
I'm planning a 455 swap and I'm hoping to find a 454 TPI throttle body and I'd like to get a fuel injection gas tank for my boxy wagon.
Does anyone know if a jelly bean wagon's fuel tank would fit easily into a boxy wagon?
It's $230 for a new fuel tank for a '90 Custom Cruiser and that's a metal tank. Living in Ohio, I'd only feel safe buying a new tank because I know a junkyard metal tank would be in as rusted as my tank, though, a junkyard plastic jelly bean wagon's fuel tank would be just fine... if it fits.
If anyone has any other ideas, I'm all ears (eyes).

Oh yeah, two more things...
Were the '91-'93 jelly bean wagon tanks plastic?
I'm assuming the LT1 wagons had plastic tanks because my friend's '94 RM sedan has a plastic tank.
Are there any decent boxy wagon forums? I sure couldn't find any at all.

the bubble caprice has a plastic tank
I would say the only way is to measure out everything but I'm pretty sure it would work

On my '89 4 door I had a plastic tank from like a '91 or '92

Plastic gas tanks from the bubble/whale year sedans will work/fit in a brick sedan. It's been done a number of times. It was plug-and-play as I recall.

I don't know of anyone that has ever tried either a bubble sedan tank, OR a bubble wagon tank into a brick wagon (1990 and earlier)..... but I think it should work.... so long as the whale wagon is a TBI wagon with similar fuel line and EVAP plumbing.

The bubble wagon tanks are 23 gal vs the 25 gal tank used in the bubble sedans, and IIRC the smaller size is to allow the spare tire recess AND perhaps the use of duals (as designed but never used in the 91-93 wagons, and used in the 94-96 wagons).

one would figure a sedan tank won't fit into a wagon due to the spare tire mainly.
As I mentioned before on sedans it's not a problem at all but I've never read about it being done on a wagon but AGAIN as I wrote earlier, measure things out and decide then.

I believe it would work. I had two "Bricks" - a 85 Pontiac Parisienne Wagon (which I had for 2 weeks), and an 83 Olds CC. I bought the Pontiac first and found the tank was leaking. So I went to a jobber around town and he asked me if I wanted a plastic or metal tank. I looked at him a little bit funny, but he stated that he showed interchangeability.

Unfortunately, even though I ordered the plastic one, I never installed it, as the car was totalled two weeks later. My wife hasn't driven or worked a day since, and that was 5+ yrs ago!

I then bought the CC and it didn't need anything for the first year and a half.

I thought the 91-93 wagons had a 21 gallon tank and the 94-96 was 20.5 or something like that to accomodate the dual exhaust? The most gas I have ever put in my car (with the fuel gage well below E) was 19.5 gallons.

The wagon tanks are all rated at 22 gallons, going as far back as the '77 models (first year of the square body, aka 4th Gen B-Body) The wagons didn't get gasoline fuel injection until the '91s, so none of the square body wagons have factory TBI with their steel 22 gallon gas tanks.

The plastic 22 gallon gas tanks came along as part of the '91 redesign (round body, aka 5th Gen B-Body) for both the sedans and wagons.

The 4th and 5th Gen sedans share the same floor pan, and to the best of my knowledge so do the 4th and 5th Gen wagons. For example, the all three rows of seats on the wagons will interchange.

Sedan tanks cannot be used for a wagon, and a wagon tank cannot be used for a sedan. The sedans have the filler neck on the rear bulkhead. While the wagons have the neck on the driver's side builkhead ('77-'96)

The spare tire provision and dual exhuast should have nothing to do with the tank itself, since the closest either one gets to the tank is on either side of the perimeter frame rail. Rails that the tank is narrower than.

Going with the plastic '91-'96 wagon 22 gallon tank should be a none-issue for your '90 Olds. At most, you may have to get the '91-'96 gas tank straps which are in the shape of a "Z".

Now I don't know if any of that info is right but it sure sounds like you know what you are talking about . Thanks for clearing this up.

all I know for sure is GM redesigned the middle seat mounting in 94 so 94-96 is different (hingers) vs. metal plate to the floor on previous years.
