Pretty great tool, but if you bump the spring... I put a small zip ties around the glass portion to solve that problem!

My floatplane sits for 6 months ou of the year and its nice when almost all the plugs are still blue indicating that there was no moisture present. The ones that turn a bit pink tells me they are doing their job.

Great indicator for engine preservation as well as easy to change out with dried desiccant. Wish they sold replacement rubber gaskets for them.

Q: Do the dehydrator plugs come with silica gel/desiccant or do you have to buy it separately?

The AN4062-1 Dehydrator plugs come with the silica gel / desiccant. It is sold separately in case customers need more gel but already have the plugs.

Q: What size are the threads for the dehydrator plugs?

The thread size is 18mm threads.

Q: Do you have 14 mm dehydrator plugs?

No. We do not stock 14MM dehydrator plugs, but if you let our sales staff know how many you need, we can try to special order them for you.

Q: Will I need 8 or is 4 sufficient?

It is our belief you would want one in every spark plug hole, but that would depend on the engine manual recommendations.
