I have a slight amount of rust in tank. I've heard use bearings and gas and shake, you have any other methods?
 
same, but with old nuts & small bolts since they have nice sharp edges
 
Vinegar should work on SLIGHT rust. Problem is the rust will return if fuel level is kept low for any amount of time. Especially in humid climate. Tank should be coated after cleaning with appropriate coating. Might be cheaper to buy a new tank.
 
phosphoric acid aka rust converter if you can find the straight stuff. normal fero-pro contains some sort of plasticiser too. could contaminate. might not :)

having access to a rumbler and small 5mm ceramic beads helped in my case, but they arent exactly common... but the tank in question was pretty bad, came up like new :)

if its only minor...dont worry about it. the oil in the fuel should prevent it spreading, and...dont use ethanol fuel...
 
hang on...

you have a mixer, dont you?

cup full of sand.

cup full of 1/4 metal.

cup full of rust converter.

tape up the holes.

wrap in bubble wrap.

stick it in the mixer for a few hours... :)


be nicer if you can remove the paddles in the mixer first!

dont bubble wrap it, and run a bucket of sand in the mixer and strip the outside at the same time ;)
 
that's what the fuel filter is for. as long as it doesn't cause a leak it doesn't matter.
