First let me say I love this forum! It's nice to see people with the same interest help one another.
my 99 tj seems to have a gremlin in the fuel tank. I get different readings when fueling up. sometimes says I have a full tank and others when I turn the key it goes past full and then comes back to around 7/8 or so. I've been told its my sending unit, if so wouldn't this affect performance?
