Re: new fuel guage + sender reads max full
Fuel gauges work by the sender putting a variable resistance to ground. Varies by gauge, but short to ground is full, open circuit or high resistance is empty.<br /><br />Sounds like you are on the right track assuming a short. I suggest you take it one step at a time.<br /><br />If you disconnect the fuel sensor from the guage, do you still read full?<br /><br />If so, when you disconnect the guage do you read full or empty?<br /><br />If full, sounds like the wire has a short somewhere. If you can't trace it you might just want to just run a new wire.
