so I finally got off my but and cleaned out all the crap I had on and under the boat so I can start getting it ready for the new motor hopefully soon. I need to fix my fuel tank mounts and had a few ideas but I thought I would ask for some advice. I have the square aluminum 10gal saddle tanks in my 80 miller and they used to be glassed in. well over the past 30 years the glass has broken apart and the tanks bounce around so I need to get them secured again but not sure what is the best way to go about it. fiberglassing them in again just doesnt seem like it would last long and im looking for something that will hold them down in place. any advice is appreciated.
aside from having tabs welded onto your tanks, and glassing in gunwale supports to bolt the tanks to, theres not much else you can do other than cutting out the old and replacing with new. something to think about... if the previous ones lasted 30 years... they'll last another 30 years if done right. one thing i would suggest and this is just from putting my 2 boats together from bare hulls is to put rubber pads under them for support. little things like a rock, a stray screw, etc can wedge themselves between the hull and tank and slowly grind into them and then you'll have a leak.
thanks, yeah there is a rubber pad under there now but its hard to see. just didnt think the fiberglass would stick well to the aluminum tanks. also what would be the best way to clean off the old carpet glue and chunks left behind to prep it right so that new fiberglass will adhere? I had thought about making one long bracket to span the lenght of the tanks that would bolt to the front gunwale bulkhead and go all the way back to the transom and bolt on there with hooks that would go up and over the top of the tanks but I dont think it will work real well and add alot of weight. any other ideas?

well thats the thing... you want to use the fiberglass cloth to make "straps" to hold the tanks in. and id suggest using poly resin and glass mat for this. if you used epoxy resin, it'll stick to anything you pour it on and it would take a jackhammer if you ever needed to remove them.
