Is there any way to get a bigger gas tank for these wagons? 15 gallons doesn't go far with a 383 lol

Two ways to do it I think would be to set up a transfer tank in the spare tire tub, or remove the tub altogether, and mount in the tank out of a pickup truck or something.

Any ideas? Has anybody done something like this?

How about a fuel cell...

I’m not familiar with the wagon configuration, but I believe on the non wagon gbodies the spare tire tub can be removed and a larger tank from a Caprice can be installed.

I asked a similar question a few months ago. Got some good feedback.

No bigger replacement for a wagon. The layout of the floor they is no way without removing the spare tire compartment and making to mounts

Not to highjack this thread but has anyone found a tank for a wagon that will support stock ls fuel injection?

I'm sure you could fabricate something to work, with the original tank... maybe an inline fuel pump? But to further hijack my own thread, what bugs me is how there aren't any sending units/pickup tubes for wagons in the aftermarket.

Yeah, that's a strong possibility. Either way I go, whether I find a tank that just happens to fit or get a fuel cell, I'd probably have to cut the spare tub out. If I go with a fuel cell, and don't weld a blocking plate in place of where the tub used to go, I could probably just get it so the tank fills from the passenger side and I have to open the liftgate and the spare lid to fill it. It's got a weather seal back there already, I just have to put a new latch in place.

A 90's astrovan fuel sender drops in the stock tank and allows a walbro style fuel pump installed.
