The old ones were white, so I'm told. I cut a hole in the side of an empty margarine tub just big enough to screw in the level switch. I caulked the inside with Fuel Lube, then filled it up with 100LL. Sure enough, the float floats! Being an engineeer, I started adding washers on the centroid of the float to try and sink it. It took two #10 thin washers, weighing a total of 1.0grams. It doesn't sound like much, but on a moment arm of only 5/8", it is plenty. The "finger test" satisfied me that it would work just fine. Also, with the float hanging down away from the support arm, the reed switch inside is OPEN. With the float in line with the body of the sensor, the swich is CLOSED. Any suggestions on which way I should install the thing?
