Fuel Gauge Leak

[superpilotjustin]

Hey gang,

Does this mean there is a leak in the seal behind the gauge? It appeared like this a week or so ago and the level has stayed the same.

Thx,
Justin

That’s a liquid inside the gauge, in case that wasn't apparent.

I did an article on those gauges but can't figure which newsletter it's in. Here's a pic of what may be happening to yours. Folks get too excited when they find a leak and crank down on the 4 screws harder, which causes cracks in the aluminum housing. You may get lucky by changing out the seal in the back (https://www.aircraftspruce.com/catalog/ ... kkey=25712). They get too hard with age. The corners of the housing are un-supported hence the cracks.

On the main website page look under Resources-Newsletters and find #413 Winter Newsletter. There's a ditty on the fuel gauges that may be useful.

When you remove the gauge check for cracks.

Your gauge does not appear to have the 'no take off' markings.

Thanks, David. Must be a hardened seal since I haven’t touched those screws since I’ve owned the thing. I’ll order 2 and pay more for shipping than the seals, but well worth it.

I appreciate you referencing the Tech Talk article. That was very helpful in understanding how the only thing works.

Will check for those cracks.
