Fuel Tank Drain Plug Protector
The armor for the fuel tank on the Trooper had been bashed up against the tank, by missuse and abuse. Must have been the former owner. Either way the drain plug was exposed below the armor. Bad luck and the right rock might knock it out or hole the tank by pushing the plug up into the tank.
So I dropped the armor and beat the dents out of it. Then I took a 3/8ths thick peice of rubber belting that was about 6" x 6" and using a hole saw cut an 1 1/4" hole in the approximate center. I placed this piece of rubber around the fuel tank drain plug and reinstalled the armor.
