Fuel gauge?

[IMIX]

As far as swapping the low fuel indicator bulb with an LED, couldn't you just put a resistor inline with the LED to limit the current to it?

I am getting ready to put an XJ tank on my special, and with the few checks I have done, it seems that the wiring is all the same, but the thermistor just switches the light. I am thinking that plugging the connector into the XJ sender and then using the wires that went into the red eye to drive a gauge would work well.

Only thing I am not sure of is if the gauge model works on a reduced voltage. Most older cars had a 5 or 6 volt regulator in the fuel gauge circuit. even at that, it wouldn't be at all difficult to regulate that circuit.

As for the sender not fitting the tank on a special, I'd bet the float arm could be reshaped or shortened to the point it would be workable.

Thems my thinkins on it anyhows.

IIRC the guage runs off 7 volts which is of course regulated down by a device under the tach.

If it turns out you need it, I have a 12 to 6 volt reducer. It's yours for one beer.
