Storing Emrty Fuel Tank

[chiefmd]

In the process of rebuilding my 77 280z. Pulled the tank and cleaned out the rust. I am not going to be reinstalling it until at least next year so I would like to  know if anyone has any suggestions as to how to store so that it won't

rust again.

I use something like this in my spare engine.  Seems like it might work in a tank.

I would use tank sealing product. There are several to choose from: POR15, Red Kote, Caswell, Eastwood tank sealer

I take the tank off my motorcycle every year for winter storage. Drain it completely and then (on a nice sunny dry fall day), let it outside in the sun to dry for the day.

Once it's completely dry inside, I put it in the basement where there is a dehumidifier. Doesn't rust if you keep the humidity low with the dehumidifier.

My first thought was the same as Zed Head's.

when I was in college I would drive my RM250 up a flight of stairs, park it under a raised up bunk bed in the dorm, and pull the fuel tank and put it on the outside window ledge...

That definitely sounds like college!

That's a great story!  

Before going on vacation I wanted to put my KX80 inside my Mom's upstairs apartment.  Never considered the perpendicular railing that met me at the top.  One of the dumbest things I've done so far.  I was 13 then and close to 50 now so I'm sure they'll be more to come.

Wait!! I knew you looked familiar!!  You're D-Day, right?

You almost ran over me one night while I was playing guitar on the stairs!

Ok. After doing some more research and reading I think the suggestion to use POR 15 is the winner. I have cleaned out the tank with Evaporust and its is really clean. I was wondering if I need to use POR 15's complete kit, marine cleaner, metal and sealer or can I just add the sealer? Thanks for all the input.

Seems like solving a problem that doesn't exist.  Tank sealants are designed to seal holes, and they come with their own risks, like clogged ports, failed drying/curing, etc.  You have a nice clean tank apparently.  On the other hand, if you're just looking for another project, why not?

I'd hang some silica gel inside and seal it.

WOW.... Zhead I never thought of that.That could be my answer. I think I should try that for a couple of weeks and see what it yields. Thanks for thinking outside the box.
