Jerry can rust

Not really answering the question !!!!

A logical answer dbish. A good rinse out and keeping fuel in should stop the rust.

Sorry for the sarcasm.

I must admit my steel jerry cans are for long term storage of petrol & kept full. I find plastic jerry cans dont cut it for that use.

The rust is a result of water and air... so dbish got it right.

The filter IS important though.

hi josh
from my many many years of handling fuel as a farmer and 4wder i have trouble excepting your advice re---- if the first few litres is ok discard the funnel and fill up as normal ----
well this is totally contrary to what ive found from my experince the dirty/contaminated fuel is always at the bottom of the container and thats when you really need a mrfunnel/filter
cheers and have a safe and hny

Sorry I didn't make myself clear enough. I meant when filling at a bowser check the first few lts then ok fill up. This is mainly for moisture in the fuel. Out of the jerrys I used it for the whole lot. I agree the crap is always on the bottom.

i have used these funnels for years in aviation.
i only use 'fresh' fuel and not fuel that has been stored (by me anyway), apparently this is when fuel is most likely to absorb moisture.
however, how would you tell from the first few litres if there was water in the fuel?
i use the funnel then throw away the residue.
i think the funnel works on the principle of water molecules being too big to go thru the mesh, so they collect in the bottom.
i have a fuel tap at the lowest point of the fuel tank to take a sample in a glass jar to visually check for water.
you might do this, but do not say, but your method should at least include pouring the residue from the funnel into a clear inspection jar.

Sorry I thought there would be an amount of common sense in this but obviously not.
Put the fuel through the filter. After a couple of ltrs or what you think would be enough, then pour the residue ( that is the stuff the filter has caught) into a jar and inspect for water or contaminates. If there is none then it is your choice to continue with or without the filter. If you find contaminates it is then your choice again to continue with or without the filter or choose not to continue filling from that point.
I thought it would be obvious to check the fuel for contaminates after filling with a few ltrs so I didn't mention it.
Hope this has clarified any concerns.

Before you go and throw it away.
Ive had good success with putting in a cup of metal screws/ nuts etc, and some diesel in the bottom of the can.
Drive for a few weeks with it in the back/ on roof / whatever.
Empty, rinse, and inside the jerry is clean and debrits free.
Also works on that pesky marone brown paint that the old DoD jerries used to have coat them, and it peels off.
