Thread: Fuel Smell and left tank loosing fuel

    Fuel Smell and left tank loosing fuel

    While there are a number of possible causes (fuel senders, fuel lines, etc.), the most common cause of this is a seeping leak from the fuel selector valve shaft. Remove the selector handle and pull off the guard, then look at the shaft for a blue stain. The typical symptom is seepage that causes an odor, and a stain on the valve, but not enough to run down inside and drip out of the belly where it can be seen. There is a lot more info about this on BAC, including repair instructions I wrote and posted, for free downloads. I also sell an inexpensive o-ring kit with lube, to repair the valve; it is $11 to BAC members, shipping included.

    If you don't see a stain on the valve shaft, you'll need to pull the access panels off under both front doors to examine the senders, and remove the floorboards to examine the fuel lines.

    I fly a 1978 Sundowner and it continues to have a severe smell of fuel
    in the cabin when opening up the doors after sitting a while. I have
    seen a quarter inch of fuel disappear from the left tank over a weeks
    time, but never have seen any fuel leaking from the plane. Mechanic
    said he dosn't smell the fuel, but other people do. He has spent
    several days looking for a leak and has uncovered nothing.

    Any ideas?

    Fuel Smell and left tank loosing fuel

    I found that the fuel pressure gauge on the instrument panel had a leak from
    the line going into the gauge. I gave it a little twist and I have not had
    the smell of fuel since.
