I did the tank for my '59 Austin Healey myself using the method described. The secret is to use the right tank sealer. Find Bill Hirsch's sealer, a few companies sell it, Bill even sells it direct from the web. It is by far the best I've found and it will handle ethanol no problem. The FC should be really easy since you can remove the pump and pick up.

Thank you!

Thread resurrection.
So I was replacing my fuel filter today along with checking out my fuel-pump-filter.
And found a layer of particles on the bottom of the tank.
So Sunday I'm dropping the tank, and cleaning it myself.

So whats a really cheap way to do this, materials wise?

I was thinking water flush, then paint-thinner/acetone/etc flush.
Purple power flush?
What do ya think?

call a few radiator shops, ask them if they have a boil tank that can take care of gas tanks.... cheap and easy to do...

Muratic acid is not recomended for big gas tanks, works better on motorcycles and moped style tanks.

Sludge factory.
 

So I dropped the fuel tank.
I wish I took better/more pictures (will post up sometime this week), cause this was awful.

So the tank had a layer of brown gunk coating the insides.
The rectangular little basin right under the fuel pump, had maybe an inch or 2 of this brown gunk in it.
It was so bad, I put the fuel pump back in, and it wouldn't seat on the tank, i had to wiggle an push on it for it to seat.
So the bottom of the fuel pump must have been sitting on the pile of gunk.

Its all out of there now.
You can actually see metal now.
And the walls/separations are not rusted through.

I 1st flushed it with water from the garden hose, then put purple power through it, then flushed with water again, finally flushed with a quart of acetone.

Putting the tank back in was a pain.
But I got it done.

I think I actually felt more power when I drove it. ha ha ha.

Pictures.
 

Yeah, that brown gunk came out of the tank. There was chunks actually.

Ok to make this post more...

During DGRR I had no problems at all with left turn fuel cut, etc.

It was very fun.

I have had great results cleaning inside tanks with a kit from Summit Racing. Its only like $50 and has a cleaner, a primer, and a liner in the kit. It works wonders. Good luck...
