Leaking petrol tank

There is a more common leak when the overflow pipe rusts through,but in your case I would get on Ebay and look for another tank.If it has rusted through in three places,I don't think it will stop there even if you could get it repaired.You can get one really cheap if you don't mind a small dent or two,but a smart one will set you back a bit.

I scraped away a bit of paint and poked around which caused the leak to get a whole lot worse, i had to get the tank off and drain the petrol out (not the easiest thing in the world to do without a on/off switch)
Anyway after further probing the tank has 3 holes in it, left handside bottom of tank near the seat.
What i want to know is;
Is this a common problem and has anyone else had this trouble. It had been known in the past but would not call it a common problem.
Is it repairable and would anyone risk welding it. It's a whole heap of effort to do this and more than likely not cost effective to do so.
Will i need a new tank Basically yes
How much is a new tank LOTS over £300 from Suzuki
Also does anyone know where to get a replacement tank or has anyone got a yellow tank for sale. Ebay is your best bet. I picked up one with the smallest dint in the side for £35
My bike is a naked 99 model. So you can do a search for an SV tank all the way up to and including 02
How can a tank rust from the inside out so quickly. It can happen. Just bad luck it's your tank. Rust spreads like the plague when it sets in
Thanks in advance. Your welcome

Hmmm, :-k

I've heard of people welding petrol tanks for cars,they just fill them with water before they start to weld.Avoiding the possibilities of fire/explosions.

thanks for speedy replies
Bloody hell 300 quid! but im off the road until i get it sorted.
Here is the place of the holes

BLIMEY!!!! :shock:

That looks like one of the 'lowest' points of the tank,also,the bike when parked,would lean to the left,making it EVEN lower!!!

I would say that is the result of Water sitting in the tank,it tends to sink to the bottom in fuel,causing it to rust.
Water is sometimes found in 'dirty' petrol station tanks,and when they get low on fuel,the pumps drag it up.

I still recon you could get that repaired,it's worth a phone around!!??

I am going to take the tank to the bike shop tomorrow to see what they suggest and to see if they can possibly repair it.

Rubbish! Slap some Araldite over the area (and the same place on the opposite side of the tank for safe measure) This will give you at least another month for you to find a replacement tank! Worked many times for me!

The tanks are not supposed to be run low enough to suck the rubbish up!

Anyway,I recon I could weld that,and my welding is far from excellent!
So someone decent should easily be able to do it!

I was going to use araldite but was told by someone that it would only last a couple of days if lucky!, anybody else know if araldite is used for this type of repair or is there some other resin type of fix available?
