first thing to notice is the sender units range "0 ohms empty, 90 ohms full" you will need to find a guage that runs in that range ..
could try measuring the std guages ohm readings at full and empty to see if you can use the std guage.
the tank has tabs for mounting, you will need to see if you can use an RHS or angle frame where the wheel well was if you are cutting that out and mounting under the car ... im not sure if the rules for Andra will require this to be enclosed in sheet metal or not... so you will need to investigate that.
