The sender in the tank normally works like a variable resistor, the resistance changes with the fuel level. You should just need to hook it up to the wire from the fuel guage in the instruments (??)

I'm with Murcod. Increasing resistance commonly indicates less fuel, if this helps.

It's not uncommon for the signal to pulse - don't understand why, but don't be disturbed if you notice this.

Cheers,

Scott

expanding on what murcod said:

12V +ve to the guage.
from the guage to the sender
from the sender to the ground (-ve)
