    oil pressure sender working as fuel pressure sender

    is it do-able? i've had a t-piece made so that i can use the audi oil pressure sender in my fuel line on a different car, how would i go about wiring it up? will i need to have an earth off the body of it and the signal wire to the gauge?

    Its possible fuel might kill the sensor. Not sure but its a bloody good idea of it works.

    You'll need a hot wire guage between +v and earth is normally fed from the sole pin from the sender. +v should come via a voltage reg or you'll get a fluctuating needle with engine revs.
