Re: [HSS] One more time - Fuel Sending Units

Unknown

There is no way you can switch the leads on the back of the gauge - one

receives voltage from the ignition switch, and the other goes to the

connecting switch for the sump and tank. if the gauge reads backwards it is

just a case of getting the float to swing the other way by bending the arm

around 180 deg. Any 180 ohm rheostat whould work with a reasonable amount

of accuracy - after all, you don;t really need to know how many gallons

exactly you have in the tank, just so it registers empty tank just before

the tank actually runs dry. Mine read 7/8 at full, and starts t flicker

below 1/4 full, so I know it's time to head to the gas station. Good

luck,

Geoff.
