I recall reading about the nuts and bolts, steel, to use on the inside of the tank. Already familiar with cleaning the inside of a gas tank with my Ducati.

I'm sticking with the fuel filter though. I had looked at it before my trip and thought it looked dirty. Already dated the new fuel filter and bought a dozen more. Just have to stay on top of it. R&R a fuel filter is much easier than dealing with cleaning out the carb.

Although I'll be pulling the carb apart this winter to check it out and clean it.

Thanks for the help!

Glad to hear you got the problem figured out. Thanks for the update. To remove rust from your tank, I recommend draining, flushing with water then filling it with EvapoRust.


This product is not an “ acid”, it’s not corrosive, will not damage the bare metal. It’s a chelating agent that simply removes rust , all the way down to the metal. It’s safe to handle and water soluble so after treatment you flush the tank with water.

If you have enough rust in your tank to regularly clog the strainer and/or an inline filter, you need to address the rust in your tank, that is too much.

I am a fan of white vinegar, super cheap and will not eat your paint. 24 hour soak with a slosh every hour or so will get her done. Rinse with more vinegar, then water then gasoline and mount on the bike. $1 a gallon at the grocery store. I would reinstall the inline filter for about 250 miles just to get a visually indicator if you got it all out. After that if the filter stayed clean I would get rid of it, in tank strainer is enough for normal duty, good luck.

I cut open the fuel filter and you see the junk it stopped from going to the carb. Looks like coffee grounds on the concrete.

Good grief. Is there a fuel strainer in the fuel tank and does it have holes in it? That's a lot of junk right there.

Earlier post with pictures showed the Pingel petcock with screen had this same junk. Really affected my last trip.

That's not enough rust on the screen to block fuel flow.
When was the last time you replaced the fuel line?
They rot out from the inside and send rubber bits into the float bowl.
