there are at least three, one on top of tank (inaccessible, you'd have to drop the tank) and two on both sides of tank at its bottom, you can see them once you remove rear seat bench.

my fuel level i think doing problem unde 1/2 tank

any idea which one is responsabile or control under 1/2 tank or which one i must replace driver side or passenger side { where is the feul pump }

[julex]

no idea... but they are simple resistors in series so with electrical diagram you should be able to figure out which one is acting up.

Must be that time of year. Mine started doing the exact same thing intermittently. Sounds like a pain in the A$$ though.....I'm just living with it for now. I'm hoping it fixes itself.....but I ain't placing any bets.
