    Fuel gauge issue, possibly the "Fuel Level Sender Assembly"

    My fuel gauge is showing my tank on E. When the key is turned, the gauge flips all the way up to Full, then immediately drops back down. From what I've researched, the problem is most likely the "Fuel Level Sender Assembly." I'm getting a little confused because when I search for parts on...

    Fuel gauge

    I have a 92 k2500 and I swapped in a gauge cluster from a 94 suburban. I have a 34 gallon tank and the suburban has a 42 gallon tank. My fuel gauge reads as not full even when full which makes sense. I am just wondering if there is a relatively easy way to fix this or if I should just live with it
