I have on old pickup, dodge-200 1962, that someone has added saddle
tanks to. I have not used these tanks so the gas in them is atleast
15yrs old.

I have used the main tank for all these years so everything from the
main tank through the 3-way switch and to the engine is OK.

What is the best way to clean the tanks up so I can use them?

The tanks are well-build thick gauge galvizined steel, brass fittings
and copper tubing runs to a 3way switch.

More details:
When I removed the gas cap it has sealed itself with varnish and there
was a lot of creamy colored residue inside the filler neck. When I
removed the gas line no gas came out. It too was sealed with varnish. I
had to poke a hole through the varnish with a wire to get the old gas to
run out.

The gas is a deep reddish color.

Any help or advise would be welcome.

Syphon out all the old gas you can and put a gallon of solvent in and
drive it around for a week to losen up stuff.

Clean out the tank well with solvent. Fill with water and drain 2-3
times. Provide plugs for the nipples and filler pipe, and take the tank
to a sandblaster. Have the exterior blasted to bare metal. After
cleaning, blow off all the blasting residue from the seams, wipe it down
with solvent, and paint the tank with marine epoxy, adding colorant if
desired. A nice thick coat. Let it cure for a week or more. The epoxy
will seal any small perforations or seam leaks, and if you can keep
water out of your fuel, the tank will last pretty much forever. There
are products to etch and seal the interior, but their performance is
dubious.

there is stuff called "sloshing compound" used on aircraft gas tanks, also
sold to the antique car hobby (where this is common - my 36 cad had a hole
in the gas tank you could put a gerbil through). clean the tank, if you
suspect the metal, you can use the sloshing compound.

I have heard that a phosphoric acid solution will clean gas tanks out very
well, not sure of the concentration needed, but probably low, follow with
boiling water & baking soda rinse to neutralize, blow out with compressed
air, and then acetone or alcohol rinse to displace any moisture left by the
water/soda rinse.

Do a little "google" research.

Acetone will dissolve that varnish. It will take a bit of agitation,
though. I'd drain the tank, get a long inspection mirror, and look
around in the tank to see where the level of the varnish is. Good luck
with doing it with the tanks mounted on the truck. Perhaps a drive over
a bumpy road?

Watch the line wrap. You'll probably need to cut & paste the URL to your

You might also drop in a handfull of big lead shot to agitate and
burnish. Won't hurt to leave it in there after they are put in service.

Eastwood is an auto restoration supply house. Great catalog, prices
are a bit steep, but lots of unique things you can't get elsewhere.
They have a line of products for gas tank repair and reconditioning.
If you can't google 'em up, I'll check for an address for you. Great
customer service.

It goes without saying, I hope, that you should never approach a
gas tank with any sort of flame or cutting tool. I went to a call
5 years ago or so for someone who was torch cutting an "empty" gas
tank. He did not do well after the "empty" tank exploded.

Take them to a radiator shop and have them hot tanked.
Oh,....let them keep the varnish.

Best advice so far. It's not that hard to drop the tanks. You will also have
to inspect the level sending units.
"Hot tanking" is what the professionals do for a good reason.
