I've configured my standard Ford Focus ST170 fuel level sensor to work with my AIM MXL Strada dash.

You'll need access to a workshop manual or TIS equivalent for finding out the level sender wiring location obviously, but it's normally a 3 wire setup - power, ground and signal.

I'm pretty sure the stack 52mm gauge is nice and configurable for setting a 'minimum' and 'maximum' resistance level and will remain linear between.

Bit of homework with a wiring diagram, a multimeter and a mate putting a litre at a time into the tank should prove helpful
