lean problem

[4x4]

hi
i got my car going today. it was the first time in a few months and when it reached halft the tank it went lean on idle. i don't think its half tank lean because its not lean when you Accelerate. the idle speed is also good so i don't think its that. any suggestions?

might need a small adjustment on the lsn, or you could have a small air leak somewhere.

from what you describe, 1/2 tank lean makes sense. when the fuel level drops below the 1/2 way point, you get much less gravity feed & rely on the pressure to push that fuel up hill. its probably not just happening at idle & then it stops when you give it throttle, your prob just not noticing it as much.
