I'm finally going to drop the auxiliary gas tank on my 85 28' Regal to replace filler and vent hoses since they leak when the tank is full. This is an aluminum tank, installed by Barth when the unit was built. It has a drain plug on the bottom and that is where my question begins. I originally thought it was a Allen size of some kind, but now that I'm into it, I'm not sure. First of all, it looks like the plug is made out of lead. Honest to gosh, I mean it's really soft and it's been butchered up a bit and now I'm wondering if it's a Torx size of some sort. Even if it is, how in the heck do you get something made out of lead, or some kind of soft metal, to come out even if you can figure out the size and configuration to begin with? I'm afraid if I put any pressure on it, I'll just wallow it out to a round hole. Would appreciate any suggestions.

If it doesn't leak, I would leave well enough alone. Seemingly simple things can go wrong in very complex ways.

I agree with bill h - leave well enough alone. Use all the fuel you can out of the tank, or siphon it, then remove it. I use a motorcycle jack padded with foam to remove tanks, transmissions, and the generator on my Breakaway.

Note, you may need the special tool to disconnect the fuel line.

Rusty, you mentioned a special tool for the fuel line. Without taking the tank down, all I can see is two rubber fuel lines coming from the tank to the gizmo that switches fuel supply from front to rear. I can remove those at the gizmo location since they are attached with metal clamps only, but what do you think I'll see when I gently drop the fuel tank down? I'm going to use a floor jack and a piece of plywood with some padding between it and the tank. Also, I'll remove the fuel filler hose and the overflow hose at the tank and then after I get the tank out, see where the other end of the fuel filler hose is attached. Think this is a plan?
Thanks
Jim

Whenever I drop a tank, I take it all the way out and empty it completely, then rinse it again with a little clean gas. Sometimes it is scary what is in there.

It would also be a good idea to replace the intake sock filter and the sending unit gasket. And really clean the fuel level elec terminals. Cut an inch or so off the wires and solder new lugs on the wire. It is a little extra trouble, but could avoid aggravation later, and now is when it is easiest.

If you have standard hose clamps, you'll not have the quick-disconnect connectors they may have started using them in later model years.
