Water in fuel tank

**poloplayer** · 01-02-2011, 11:28 PM

Hey guys, The Suzuki forums not very useful, so I thought I'd ask here since everyone here is so awesome

anyway, my gf was in a bit of a rush as she filled up her 09 swift, and as you do sometimes, spilt a few drops on the paint work below it. She then used the water can to wash it off, but forgot to put the fuel cap on before doing so

long story short, she started hearing a very slight buzzing noise a few minutes into the drive home. My question is, assuming that theres only a little bit of water that got in, would everything be ok other than the temporary noise? She did fill it all the way (40L tank) so I'm assuming it'd be diluted quite well. Cheers in advance

in the "olden days" if you got water in your tank you'd throw in a bottle of meths to help burn/disolve the water.

do some reaearch but I suspect that will fix your problem, if there isnt too much water.

two other thoughts: 1/ water doesnt compress very well, so you dont want it getting in your cylinders, and 2/ if you leave it in the tank too long, if you have a metal tank, it will go rusty inside, reducing the life of your tank, but also creating havoc with your fuel filters

I wouldnt think water would corode metal faster than fuel and who has a metal petrol tank anyway?

If you are really worried just flush the tank, you'll loose 40L of fuel but might save alot of hastle later on.

+2 to Metho. Add a litre to every fill for the next 3 or 4 tanks.

Also, some Nulon Total Fuel System Cleaner wouldn't hurt either

My mk1,mk2,polo, merc 230, vt commodore, vs commodore, vx commodore, 180sx, bora all have plasic fuel tanks....or at least they look and feel like plastic from the outside.

MK1 tanks are steel. I've never seen a plastic one.

Also there are other metal parts in the fuel system than the tank, which cannot be just removed and flushed. IMO, Interject products are the best when you have water contaminated fuel.
