I need to open up my diesel tanks
. No one has looked in them for 26 years. Want to get them all cleaned out and the fuel
polished. Also need to open up the same ports
on my water tanks
. Have some type of air bleed into the water
line screwing up the water pressure to my system. When the tanks are full, the tanks pressurize fine. When half full, the pump goes on forever. I need suggestions as to what material I can use to reseal the tanks. Some one suggested a neoprene material but I thought it might leave a strange taste in the water. Another suggested silicone caulk. Again, the chemicals.
Thoughts and suggestions please?
