i need to install a gas tank and i noticed to remove the old one i need to unscrew the 4 screws that hold up the 2 straps. what else do i need to take off to remove the gas tank?

I've never done a Bonne but typically you'll need to lower the tank a bit and then reach in and disconnect the pump wiring before lowering it the rest of the way.

Same goes for the fuel filler neck if you can't get to it before you start dropping the tank.

2 bolts. Only the front two. Then the straps pivot out of the way.

Disconnect the two fuel lines on the passenger side.
Lower the tank a little and disconnect the pump/sender wiring.
disconnect the filler hose and vent line on the driver'* side.

Blow off all the dust around the sender. NOT a VACUUM or any other electrical device.

Turn it counterclockwise with a screwdriver and small hammer. You'll need a new seal to put it back.

Please, disconnect the battery first.

That'* a good SAFETY but not actually much of a hazard. The tank is still sealed when you pull the connector at the tank, and that connector has no power to it with the key off.

thanks alot prob gonna work on that tomorrow
