, you need a 1992-97 chevy suburban tank. If you look on ebay you might find a new one for under $200.00. If you look at the tank one end is a little narrower then the other, use that as the front , the inlet tube will be on the wrong side. have the intake moved to the passenger side of the tank and the old one blocked off, and a drain plug put in the bottom. if you are not going to use a chevy pump in the tank then you will need to have a pick-up for the gas line installed for the line to the engine. Or use the chevy pump that goes in the tank. if you go that way you can check ledmine products on E-bay for longer tank straps and an adapter to connect the chevy level to the toyoto fuel gage. Or if you want to use a toyoto sender unit I just made an adapter so that I could install the sender in the fuel pump hole. then install in the same place as the toyota was.Well now..I would suggest some pictures and a description of how this was done. I am intrigued.
hope that helped.
