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.

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?
