Gettingt rust out of an old moped gas tank?
I picked up an old moped today just for the heck of it. The price was really cheap, and I just couldn't pass it up. Anyway, the gas tank is bone dry and there appears to be some rust in it. Should I be concerned about getting the rust out, or just put in a fuel filter or something in the line? What do you think?

I'd surely get out as much rust as possible. Along with a fuel filter, you shouldn't have anything to worry about. You might have the fuel filter out a couple of times, though. 0 -
A fuel filter won't keep the rust out of the carb. You'll need to clean the tank.
Go to a motorcycle shop and get some tank cleaner. It's basically acid and a neutralizer. Yamaha sells it and a couple other companies too.
Don't use that creem sealer in it. That's a band-aid repair. And it will come loose and you'll have worse problems.
Just stick with the acid cleaner and keep the tank full of fuel.0 -
Is this a 2 cycle or 4 cycle? if 2 cycle forget rust and add a fuel filter. If it's a 4 cycle then try to remove the tank, add marbles and shak it around. Empty ,then if your not satified use muratic acid. Rinse very well with water and dry with air. ( compressed air works well.) They also make a plastic coating for gas tanks. Any good bike shop can do it or tell you where to get it.
Good luck.0 -
Reach down its' little throat and grab its' tail from the inside, then pull like hell and when you have it inside out, sand it off. Then reverse the process.
Hope that is helpfull.

Remove as much of the rust as possible. And install a juel filter also. 0 -
Eastwood makes a kit that uses epoxy to line the tank.

It's the best I've ever used, and they have a small size for cycles for $34.00.0 -
Get some fish tank gravel and put in it. Shake it around for a while then rinse well with a gas and oil mixture. Old bikers trick. 0 -
Pour some lead-shot in it - shake it all about to get the rust loose.
Blow out as much as you can with compressed air.
Fill with fuel, add a filter..
Have done this a couple of times.
Old mopeds doesn't have the tight tollerances like new crotch-rockets have.
Also - take the cylinderhead off, check the cylinder walls.
Perhaps take off the cylinder, clean the piston and give it some new gaskets - lube with fresh oil on the piston and cylinder before assebly.
Give it a new sparkplug.0 -

Dang Doug, I just spit tea on my monitor.0 -
toilet bowl cleaner with gravel works best, then rinse with gasoline. let the cleaner set overnight and shake it real good , then flush out with water before rinsing with gas 0 -
I have found that BB's work the best on rust in a metal tank.
They are heavy and small enough to get into places that gravel cant.
Just remove the Petcock (fuel shut off valve) if possible. For a lot of them have a small plastic mesh screen that gets clogged easily.0 -
What kind of moped is it ?
In 1965 I had a Sears Allstate moped.I found out real quick why there should be a cover on the flywheel.I still have a big hole in my leg where it tried to eat me.
