Filler up with evaporust and a bunch nuts, bolts, pennies. Cap and shake shake shake........I wouldn't use water, but that's just me...evaporust has water in it anyway so idk

I flush my tanks with water after soaking with vinegar.

hold the moped upside down with the hose stuck in the gas tank cap or have some spray the hose into the cap.

Make sure to let us soak for a good week.

All the heavy stuff comes out at the end so Ull have to flush it multiple times.

If your trying to flush thrue the petcock hole it’s just frustrating, to small and takes for everEdited 1 time(s). Last edit at 02/04/19 10:30PM by countryboy1.

You'll probably never get it all out .

Exactly why it's recommended to run an in line fuel filter good to at least 60 micron .

I use oxalic acid for rust . It does a very good job .

If you want to rid yourself of rust in the tank , you should always keep the tank completely filled or line it with a good epoxy resin .

An excellent choice :

Did Final Flush Today, In the end Vinegar soak did the trick, Then tip upside down send gunk out of filling hole with Hot water from hose flushed till water tank wa empty, blow dry thoroughly and reinstall cleaned carbie and fresh gas with a taste of mystery oil zoom zoom runs like a champ......

I would not use Evapo Rust for this tank again a bit to heavy duty for this prodject....cheers

get a real petcock, it has a filter on it that picks up higher than the bottom of the tank.

Do this like a hundred times letting it empty completely.
