Flush Out Gas Tank

Post by Syd »

I would be keen to know what is the best product to use apart from petrol to flush out and clean a petrol & oil tank after paint dust got inside after painting - the painter in his wisdom removed the rubber bugs on the tank inlets. I have used compressed air which has helped blow the dust out but I just need to flush or wash them out to be 100% sure. Maybe Kero or WD40?

Thinking diesel would be the best to use as it will help attract the "fines" inside the tank - maybe use 1-2 litres inside tank, shake and drain out. Not sure if diesel naturally dries out over time or if it would be best to flush a little petrol through the tank and drain once finished?

Diesel is more 'oily' as it's less refined - despite the price. I'd use 'super' petrol though, rather than the cheaper ethanol rubbish that's actually hygroscopic (attracts/retains water) and will rust a tank from the inside, out.
Or if you're flush, use thinners. Your choice.
Personally, I use diesel and fuel filters after.

Personally. I would use the fluid that you are planning to put in it. I.e petrol. Apart from paint thinners, nothing else is volatile enough to dissolve the overspray and if you don't, your first tankful will just do the job anyway.

Are you worried about damaging the paintwork? Kev

Thanks - just to clarify, I don't need to dissovle anything - I just want flush or wash out the paint dust that's got inside the gas and oil tank. I have blown most of it out but just need to remove the fine stuff in the dead spots.
