Probes for thick-walled holding tanks?
I'm looking for probes that will work on a couple holding tanks that have 3/8" thick walls..
A friend of mine had ProTanks whip up some custom holding tanks for his 73 Tradewind, and the walls of the tanks are too thick to use the Horst probes he ordered..
I tested the Horst probes on a 1/2" thick piece of plastic to see if they would hold, but as I started tightening up the nuts, the probe started backing itself out of the hole, which is what I assumed would happen since the rubber washer on the probe couldn't flare out on the inside of the tank.
Soooo, does anyone have any recommendations for another brand/style of probe I should look into? Possibly some that can be screwed directly into the side of the tank?
Any input would be super helpful. Thanks so much!
