Re: [T3] rusted tank was: Questionsconcerning fuel injection

["Allan Williams" <allanw@ihug.co.nz>]

The POR-15 fuel tank kit (which I have used) comes with a cleaner of some
knid. It says to use gloves.. REALLY DO use gloves :-) I gave my hands their
equivalent of a chemical face peel :-o.

The POR15 kit worked very well - I wanted it perfect on the inside, an the
EFI Subaru Impeza engine wouldn't like blockages or lean running etc!

To clean the rust, the acid you need is phosphoric acid (that's what is used
professionally). You use it diluted in water at a concentration of about 10
to 15 % in volume. I don't know for you but I can find it everywhere
(supermarkets) here in France in 2OO ml bottles (concentrated at >65%). It
is not a very dangerous acid, but it's YOUR skin and eyes you're dealing
with, so usual disclaimers apply ...
It -dissolves- the rust, and works really very well. You pour it in the
tank, let sit for a couple hours, rinse, dry (quickly as it will rust
again), et voila. If the tank is almost rusted through you'll get a hole, as
I said it dissolves rust, that's what sealing stuff is for, otherwise you
don't really need the sealer.

I use it to clean all sort of rusted parts with success. Lately I cleaned
all the sheet metal parts of my engine.
