I never knew that rubber would cause a problem until I read that article. Good to know BigLew. Thanks.

TRL5,

If I may, pls. re-read the part about 5200. 5200 is applied to the plastic bed strips to preclude any moister becoming trapped against the aluminum. The tank is NOT recommended to be 5200'd to the shelf/base where it sits, but rather just set in place using the weight of the tank + fuel to prevent shifting. Most of the tanks I have seen, including mine have some aluminum tabs welded to them and then those tabs are screwed into the sides of the well that the tank/coffin is set into. A fine point yes, but think of someone trying to remove a tank 5200'd into place. THAT would be a "NIGHTMARE on ELM STREET"(and any other street as well)!

thanxs lew maybe im not understanding it right but looks like he means the wight of the tank will make the 5200 sqeeze out just enough to bite the glass? mabe 4200 is the way to go? was going to use the tabs aswell and 52 or 4200 them to the stringers.looking forward to some feedback.

TRL5,

The strips are attached to the bottom of the tank so the 5200 squeezes out to the the edges of the strip, thus preventing ANY water entering an opening between the strips and the aluminum. His point is that water sitting in continuous contact with the aluminum is the culprit in promoting "corrosion/pitting/weakening of the aluminum. The strips being 1/4 - 3/8ths thick provide passage beneath the tank of any water in the "coffin" to flow back to a drain to the bilge. The tabs are then screwed to the sides of the coffin using an epoxy resin barrier between the screw and the core in the sides of the coffin. (NO WATER Intrusion of the coring) That's it. Just be sure to use some amount of flexible fuel line so, if the tank should shift within the coffin, no fuel line will be broken or cracked.

10-4 will secure tank by just the tabs w/ screws and 5200 maybe afew shims on the sides.
