WEll its dropped (starts cursing the long bolts that hold the front of the
tank on).  We opened it up,a nd removed the floater.  PRetty covered in
rust, which confirmed our suspiciouns that the tank was rusty.  We
arecurrently (accordint to what the manual says) using a degreaser and water
and letting it sit for a while, (ok not sit, the water is constantly flowing
for the next 30 min)

WE removed hte pump as well (seems to tiny of a thing to cost 200 plus
bucks) and use da degreaser on the intake side.  nasty particles of black
came out.  Any suggestions?  WE thing we got it cleaned out now, and hope we
don't have to get a new one.

You may want to at least look into pricing a new tank.  I haven't had to buy
one for my Z, but a new tank for my old Jeep was $60.  It was well worth it
to know that it was clean inside.  And I was also able to properly coat the
outside in rubberized undercoating.

Also, if it's not fixed quite right, would it be worth the price of a new
gas tank to do it again?

Actually, that was one of our questions.   Not jstu the outside, but the
inside as well.   Is it possible to Rhinocoat the interior of a tank, so
even IF water gets in, it will not rust it?

I personally would avoid putting it on the inside.  If some of it breaks
loose, it'll wreak havoc on your fuel system.  Probably as bad (if not
worse) that the rust, as I imagine the Rhino liner stuff is petroleum
based.  Put a bottle of water absorber in every once in a while instead.

I'm not sure where to find it, but I'm sure they make it just for that
reason. To re-line tanks. It's not Rino liner but something similar

"sloshing solution" used in aircraft tanks.  Try your local airstrip.

but you do need to be careful in which type you use.

God knows what fuel injection system cleaning stuff has in it.

WEllt he tank is rusty.  Anyone know what it should cost to get it cleaned
and sealed?
Simon Telrenner - 12 Sep 2003 17:10 GMT
This is Simon, Nic's other half.....

I am still thinking that about any good rust remover or solvent would work,
swish the tank out afterwards, and drive the thing.  May have to do it again
after a couple of years, but by then maybe we will be able to send the thing
out and get it done right, or buy a new tank at that time.

Any suggestions on a rust remover.  We have heard Muriatic Acid, but you
have to be real careful to get it nuetralized, and what to do with the
waste?

Let me know.....

Swill with phosphoric acid.  Turns the rust to a stable black scale.
I don't recommend Coke, use something like Jenolite or other liquid
(ie not jelly) commercial rust remover.  Washed Pea gravel or 1/4"
ball bearings - you can count them in, shake it all about and then
count them out.  Wash lose stuff out with water, dry by swilling with
methanol (race) fuel grade 99%+ pure, not the watered down stuff -
find a drag strip / speedway and ask around.

I'm not sure what year your Z is,  I have a 76 280  and the tank started leaking
a few years ago,   a new tank was over 500 bucks,  I wound up taking the tank to
a radiator shop and they cleaned it and then lined it.   I think it cost around
125 bucks.   One of the problems with my tank is it has an intank filter that is
behind some baffles and you can't get to it.   It became clogged once and
starved the fuel pump.    Also here is a tank repair place you can ship your gas
tank to them and they will fix it good as new.   It is a good site to read up on
how a tank should be done to repair it properly.

We found a product at a local janitor supply shop called Regal Supply and
Chemcial.  I used to work for them, and remembered they had a product called
Lavar, that you could drop a penny in, and it would come out looking brand
new.  I called the president (gee, nice to have connections) and talked to
him for a few minutes, and we both agreed that this would be a great product
to use here.  The upsides are, it is not caustic, or acid. And we don't have
to worry about waste, it can go down the toilet if need be.

So we bought a gallon, and put it in the tank, and then filled the tank with
water, and let it sit overnight.  You would not be believe the difference.
We are still rinsing the loose stuff out, but the rust came off very well,
and looks so much better.

I'm guessing that junk that is coming out is what used to be the steel used to
make the tank.   The tanks hold a little bit of pressure when the gas cap is on
to prevent hydrocarbon emissions.  What I am saying is if the tank did not leak
it is apt to leak now or very soon.

Maybe, maybe not, but if we can get another year out of this tank, then we
are better off.

Well, we got the tank cleaned pressed and folded.... no wait, that was the
laundry

We got the tank cleaned, and re-installed.  Started filling it with gas, and
low and behold, the stupid thing was apparantly rusted worse than we
thought, cause it has a leak with a steady stream about a 16th inch in
diameter.  We went and bought a gas tank repair kit, and will prbably do
that tonight when we get home.
