What’s the best way to clean out fuel tank?
Not in car if helps

[mbolt998]

I don't know the best way. I blasted mine out with a hosepipe and lots of water several times until the water came out looking reasonably clean, and then fitted an inline fuel filter.

I`ve done gunky motorcycle tanks with caustic soda and then finished off with citric acid which is the same stuff you pay four times as much for at Bilt Hamber

 

Look it up on ebay it`s used for bath bombs.

I did one years ago by half filling the tank with pea shingle and diesel, sealing the openings up, wrapping it in a couple of pillows, then sticking the whole lot in a cement mixer for half an hour, it worked a treat but you need access to a cement mixer obviously.

If this is in any way related to welding or brazing repairs though please say so because that's a whole other kettle of fish

[Mark2390]

No welding or brazing, just want to give it a good clean before refitting it

when I did mine I bought 10 litres of white vinegar, after sealing the tank I put the lot in then left it for a couple of weeks turning the tank everyday. Worked perfectly, though I did add a bicarbonate of soda solution after to neutralize the acetic acid in the vinegar. Then I blasted the tank out with a pressure washer then dried the inside immediately with the aid of a heat gun, if you don't dry it out straight away it will flash over with rust very quickly. 

 

Forgot to add I used the vinegar because the tank was more rusty than dirty
