Tank Dropped (Update)

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?

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.

WEllt he tank is rusty. Anyone know what it should cost to get it cleaned and sealed?

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

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.

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.
