Re: gas tank
Any recomendations as to what to place on the bottom of the fuel tank i.e. adhesive rubber of some sort, for dampening effect ? There were (3) strips of something on the tank - when I removed these strips, they could be classified more as "goo" than anything else.
Any other ideas as to how to better isolate the tank for re-installation ?

Re: gas tank
ALB, Im going to put 3 or 4 strips of high density plastic the length of the tank 3/8" x 1"x 60". 5200 them directly to the underside of the tank while it is out and let dry, making sure it is completly sealed to prevent water from getting under it. Then 4200 the tank in place appying a good bead to the3 or 4 plastic strips with a helper put in place and let dry this should be all you need to hold tank inand it will let air circulateall around the tank this is how SP tanks recomends that you install marine fuel tanks take alook at SPmetals.com

Re: gas tank
I forgot to tell you something, that goo was rubber which has carbon in it which is very corrosive to aluminum. so stay away from the old method or mouting with rubber

Re: gas tank
Guys I just put my new tank in this week. I used 5200 to stick the platic strips (2inch wide by 1/4 inch thick lexan) to the tank every foot or so and let it set up a couple of days. I think I went just less than a foot across I think I had seven strip all together. Then I put two 1/4 wide beads of 5200 on the bottom of each strip and placed the tank back in there and put some weight on it, Real easy. Good luck [img]images/icons/smile.gif[/img]

Re: gas tank
Gave the tank a real good inspection today, there's a few deep pits, they are at least half way through. Time for a new tank. rudders you state that rubber contains carbon,is this true of neoprene also?I can get neoprene or polypropolene.I'd think twice about gluing a tank in with 5200, what if you need to remove the tank?

Re: gas tank
Rudders, are those measurements for a 23 200 gal. tank? If not, does anyone know the measurements for the original 100 gallon tank, thanks.
