So I pulled my two fuel tanks after going through several inline filters and still getting crap. Tanks were held in by some kind of spray foam almost like "Great stuff" foam. I'm thinking someone did this as a quick fix? Or is there some kind of product designed for mounting fuel tanks this way? The tanks are rectangle galvanized steel and I can see where it looks like they used to be secured with fiberglass on the front and towards the back on the bottom.
What would be the best way to reinstall these? Should I fiberglass them in or build some kind of a mount / strap?

Thanks

My tanks don't have brackets or bolt holes or anything to mount them. I would had to strap it somehow or wrap it with fiberglass?

Weld some tabs to them then glass over the tabs. Thatís how my old rectangle ones were done. Worked great

Little bit worried to weld tabs on since the tank is so thin. But ill give it a shot.

So i'm planning to put bracket on the tank and mount it to plywood glasses in at both ends like bobs.
This is the first time for me working with fiberglass so any tips or best product recommendations let me know. Or if there is a good thread or tutorial out there please share.

Resin ur wood first , let it set and repeat, when dry set up ur mounts and lay resin down and let it get tacky and lay ur glass down and use a roller , more resin and repeat till u have at least 4-5 lay downs

Did you guys just glass them across the bottom or the sides too?
How should I go about removing the old fiberglass that attach to the tank?
Should I grind it out or can I put heat on it and peel it up?

Pick up one of these oscillating tools. They are perfect for cutting fiberglass. I used one to cut the fiberglass tanks out of the Rogers.

I glassed the tanks on the sides as well.

I have the tanks out but you can still see where the overlay was. Is there an easy way to get this off or should I just grind it off?

Another question. Do I apply resin to the existing fiberglass and tank and then install the mat or do i do a dry layup?

You can trim that down with the oscillating tool and sand the rest. You might be able to pull some of that piece up with a flat head screw driver if you can get underneath it. That way you donít have to sand as much.

Apply some resin, put the layer of mat or cloth down, then resin over the top of it. Make sure you have a roller to get all the air bubbles out. Iíll see if I have any more progress shots.

That tool is the shit careful sanding down the glass on the tanks so that you donít make the tanks any thinner than they already are
