Rusty Fuel Tank

They make a fuel tank coating liquid but I have never used. Some have put hex nuts or other metal bits inside and shook it around to knock off the rust bits. Just don't post that you've got nuts stuck in gas tank.

 

Try using vinegar in the tank, I managed to get a Suzuki tank perfectly clean by using this method. Take out the pump, sender and fuel gauge, then fill it with vinegar (clear not malt!) put some M8 nuts inside the tank, tie them on a loop of string so they are easier to get out.and shake the tank vigorously leave it then for several hours, tip out the mixture, filter out the crap, put the vinegar back in, shake again and leave.

Then repeat, hopefully that should clean the tank or at least get it better than it is now!

When finished neutralise the vinegar by rinsing the tank with baking powder.

 

If you use smaller nuts you will find them more difficult to pull out. I found M8 nuts about right even on a small Suzuki moped tank I used about 8 - 10 tied on a loop of string

 

Have a look on YouTube all you need is a battery charger baking soda and water

 

Couldn't watch it all I fell asleep he has such a boring voice was he on an episode of Father Ted

 

I never miss an episode, guys an expert.

 

@Rocker tryed that myself but It was high maintenance
@Tratch after trying the electric way I too tried vinegar and it worked the best by far with no work involved!! Chuck three bottles in the tank @30p a bottle ( once you’ve got it off the bike and plugged it) and just top up with water. 48hrs should give you a dishwasher clean look!

 

Have a look at this, results are quite good.

 

I helped a mate that had a 15 year old FZR600 with 500 miles, tank was same as yours
Remove electronics, pump, sensors etc. And block holes as you see fit
1) couple pints of water and two cups of nuts small and medium, make sure magnetic
2) shake as much as you can changing water regularly
3) remove nuts using magnet and patience
4) fill to brim with rust remover treatment with hot water, 1st time for an hour or two and 2nd treatment overnight
5) rinse very well and allow to dry, a hairdryer helps
6) treat with tank sealant and allow to properly dry
Tank came up super shiney

 

Looks great

 

Make sure you buy one that will handle the Ethanol in fuel.

The inside of the tank has to be spotlessly clean and dry, follow the instructions to the letter ensuring that all of the inside is covered with the sealant.
Its not a 5 minute job.

 

Brilliant
