Hey guys, whats the best way to clean inside a fueltank, its a 1996 zx7r

Depends on how much rust there is, if there is heaps i wouldnt bother.

Make sure its dry
Put in a few 12mm bolts or nuts in to loosen up (like a scourer)
Use a small ended long handled brush to help lift flakey rust
Dont push too hard on the bolts because you can dint the tank from the inside out and dont forget to count them before putting them in

Get some Industrial molasses (eats rust)
Mix at 1:5 ratio and leave it 3 to 4 days
Empty.

Then when there is NO moisture use a fuel tank sealer.
Its a rubberised compund can pick up for about $100

or you can use por - 15 which most restorers swear buy,last cost was about $75.00 for the kit

I can vouch for POR15 did a great job on my ZZR tank

If there are no holes, clean with nuts etc then treat with phosphoric acid. No liner required. Done this to 4 or 5 tanks and all worked well. One of my GN250s I did 7 years ago and it is still AOK.

thanks for the replys i went and bought a por 15 kit so i will see how that goes

Take your time with it and follow the instructions exactly, make sure it's nice and dry before you do the coating

and let's know how it turns out

Hey Poss when you say industrial molasses is that the same as the molasses that is the by product from the rum factory that they feed the animals
