I have a 1994 4.3 extended cab. Need to replace my tank. Do standard cabs have tanks that would fit mine? What about 4 cylinder models? I know I'd have to stick with fuel pumps specific to mine but are the tanks the same size on the 4 cylinder?

I just swapped a std cab 4.3 tank on to my std cab 2.5, I think the truck tanks only came in 2 sizes, atleast based on what I saw on ebay the truck tanks were interchangeable.

According to rockauto, tanks are the same 85-95.

Update: the 2000 tank is exactly the same as my 1994 ZR2, as far as outside dimensions. The annoying difference, which I just discovered while attempting to switch pumps, is that the 2000 tank has a bigger hole. Currently trying to figure out a workaround, possibly combining 2000 pump assembly w/ 1994 pump.

Just be aware that 97-98-up fuel level sending units work on 40-250 ohms,
While 96-older use 0-90 ohms.
