Smith fuel gauge goes by rev
Posted: Wed Mar 07, 2018 8:39 pm
hello,
my Smiths fuel instruments on elan sprint, goes following the rev engine. It means that at minimum rev the instrument works well indicating the correct level of fuel, as when the engine is off only with the key on ON position). But at 1500 rev or more, the fuel gauge moves slow up to full. Stopping the car at minimum rev the indicator goes down to the correct level of fuel.
I changed the fuel sender unit by a new one; i replaced the black wiring from sender unit to ground.
Why it happens? where is the problem? how to repair it?
thank you to all!!
