I am working on a friends 1965 Ford Mustang. It has an aftermarket instrument panel with a 240-33 Ohm Fuel gauge and a stock 90-10 Ohm fuel sender. So the gauge never reads below 1/2+ (empty) and off scale high (full).

I found through Google that I may be able to install a 380 Ohm resistor inline and the low side of the gauge will read proper (which is the important side).

1) Would this work?

2) I cannot find such a resistor. I did find a 330 and 50, would these work in series to provide 380 Ohms?

3) If so, what watt and type resistor do I need to look for?

Thank you for any input.

BTW, The 240-33 ohm aftermarket senders I found are bolt mounted and do not have a fuel nipple. I need the lock ring type (like our Pontiacs) and with a nipple/pickup.

1/4 watt resistors in series will work. If speed of the deflection was paramount, I might go with 1/2 watt ( 330 +50) ohm resistor. BY putting in the resistors, you give the gauge "less ground" which is less defelection. Its basically a volt meter and full is a well grounded sending unit.

Thank you Formulabruce!

Now I just need to order them and will post results after install.
