So the mechanic says I have rust in the tank

So the mechanic says I have rust in my tank. Flakes are running through my hoses and clogging my carb and making gas leak. He wants me to have him acid wash and seal the tank. Says it will cost 500.00 any input?

No freakin way would I pay that! Just do it yourself. Of course I'd bet he's including cleaning out the carbs and fuel system.

Theres a place by my house where you take the gas tank off. Give it to them. They fill it with some sort of abrasive, put it on a vibrating machine, and bingo, your tank is as good as new. all for around $75.

Mabey look for a shop that does that kind of stuff.

or fill your tank with gravel and put it on top of the washing machine for a week. or anything else that vibrates. hahaha

Hmmm. bike, age etc.

Probably right though - I've seen bike that have had fuel leaks due to rust.

I mix a half cup or so of meths with a full tank every month or two (when I remember) to eliminate moisture (water) from the fuel system. Never personally have a tank rust.

there are lots of tank rust kits out there, or a mild electric current, the right fluid s and an anode will do the job, go to google and have a look. 500 tell him he is dreaming

Does help if you mention what you're working on.

Cleaning the carbs you can do yourself. You may just want to find another tank; if you have a rusty one, you may have holes developing soon, and Kreem/POR15/Etc is not exactly structural.

Also, rebuild your petcock and fit an inline fuel filter.

CL350 - man memories. Is the CL the one with the high pipes?

I had a CB200 as my first bike.


Always loved the 175 with the high pipes?

Post some pictures too.

You can buy rust eliminator under various brand names at Home Depot or most any hardware store. it generally has dilute phosphoric/muratic acid which will eat the rust...the good ones also have an additive to prevent flash-rusting afterwards...then you can rinse it out, and go...or seal it up with POR-15 or a similar product. on a '72 bike having rust in the tank is far from uncommon. Good luck!

Well, fire the engines! Spur this iron space-pony on!

I'd try some of this first:

If it's in the tank, it's also in the rest of the fuel system.

This is just the beginning.

I have a '69 CL 175 that I had to coat the tank years ago due to rust. If you do it yourself, be sure to tape the vents on the gas cap so they don't get blocked off with the sealant. Trust me...

Rad shop etched and treated my tank for $60...and then told me not to use ethanol in it. They obviously have no [email protected]#%ing clue how hard it is to find ethanol free gas in this area.

if you love your motorcycle, set it free.. if it comes back and hits you.. you highsided

Thank you all for the input. I plan to shop around for another shop to work on my bike. If that doesnt work I probably try some of your ideas. I'll post some pictures soon. Thanks again.

In order to clean the tank, I would use Evapo-Rust Evapo-Rust Rust Remover Home

It works like a charm!

Then, I would seal the tank with the POR-15 kit.
