They are going under the cab/bed between the frame. They are simple boxes 36"x12"x9" 16 gauge cold rolled steel with 2 baffles I welded them with a wire feed welder did an ok job but I do have a few pin holes plus it was suggested to me to use a gas tank sealer even if I didn't have any holes, so here is the question where do I get a good gas tank sealer would a parts house carry any.
One more question are the GMC gas gauge sending units the same as the Chevy ones in size I am assuming they are because Almost everything else is interchangable

Also check out POR15, think I remember reading something about a system they sell?

If it starts coming loose the thing is ruined. Couldn't you pressure test it & go over any leaks. They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Aug 2004 Posts: 242 Shop Shark | | Shop Shark Joined: Aug 2004 Posts: 242 | Year ago I had a BAD experience with the EASTWOOD product. It started to peel off and and plugged up the pick up tube in the tank. I thought I had followed the directions in the kit, but I will NEVER use that product again. It may have been a reaction to the ETHONAL fuel, I do not know. I ended using an NOS tank I found.

I have had a number of bad experiences with different sealers coming loose in tanks and clogging the fuel system. One of these experiences was with a homebuilt airplane where the builder sloshed the inside of the tank with sealer and it came loose and caused an engine failure resulting in a forced landing. (No one hurt). I suggest welding up the pinholes and forget the sealer. Just my 2 cents worth.

I plan to get the saddle tank from the 48 3100 boiled out at a radiator shop.
Weeds - you would not have this sealed?
