Rust hole in my fuel tank.

[texmo]

I have a rust hole in my fuel tank and its leaking petrol its on the bottom of the tank and the infected area is about as big as a 50cent peice. What do I do, I have looked into the 3 stage thing where it cleans then seals the tank is this just a quick fix or should I replace the tank?

Thanks to every one in advance including motu.

With acknowledgement to mr WINJA- Araldite. Works a treat. If the damage be of large extent, back it up with some fibreglass mesh, kits are available at hardware stores.

Definitely post up some pics if you can mate, hard to advise without seeing how bad it is.

Scratch up the area,see if you can poke holes in it with a screw driver.If it's just pin hiles ise POR 15 tank liner,if the are real holes you'll have to remove the tank for repair.

Scrape off the excess crud, and use "NEAD IT". I've fixed holes my fingers went through with this shit bro. It sets so hard, it can be drilled and have a thread tapped into it. Sold my XJ with a massive hole after fixing it, two years later, and no leaks.
Costs ten bucks for a tube. and you could build a whole new tank bottom with that. Great for exhaust leaks too!!!

And it's simple!!! You'd really have to try to fuck it up.

With all respect to the answers you have received, which all will work and will get you home ,in my humble opinion buy another tank if its rust damage- if you want to keep the bike. Any repair short of a proper cut & weld will fail at some time- anytime anywhere, usually out in the boondocks at best, or at worst when your having a fag whilst sitting in the shade of your bike...whoof !
The real problem is the water/rust damage in the seams where the tanks joined- it just wont go away & fuel is really good at finding a way out of anything. The epoxy repairs do work, but not forever. Theres a product called "Kreem" we use to remedy rusty tanks on jap imports, but when we see an actual "hole" in the seam line - we replace it-damage is always worse than you can see.- GP in tauranga may have one.

I'm with you on that zarinat. Fix it properly, dont bodge it. I'd do the other suggestions as temporary repairs but certainly not permanent, theres always the risk of a bonfire otherwise.

Personally I would just replace the tank, if there is enough rust to have made a hole, then there is more that you haven't seen yet too. Get another tank and give it the treatment, no more probs.

Get another tank and give it the treatment, no more probs.A cunning plan, and worth noting. Anyone else seen a ZXR do this? Is it par for the course?

[froggyfrenchman]

I just did up my honda... See (http://www.kiwibiker.co.nz/forums/showthread.php?t=32706)
And there were 23 (i kid you not) holes in that tank! $150 for a panelbeater to plug them and prep the tank for paint, included taking out 4 huge dents too!

[Kornholio]

Na the whole bike is rooted now...throw it away and buy a Suzuki :D

[Sketchy_Racer]

yep Im with Macktheknife.

Im having a similar problem at the moment. except its on a radiator.

Every time i plug one hole with knead it, another one springs up....Grrrr

[qldzxr250a]

had the same prob on my ZXR Pin holes everywhere, tried to get the tank welded but welds didn't holed (read: Rooted). So After heaps of searching came up with a new tank. Cost my Left nut($300) but i now have a perfect tank i know wont fail on me.

for me $300 isnt a bad price for piece of mind.

[texmo]

Its ok, I managed to low side my tank and make the hole bigger but I fixeed with with the help of drew, then i highsided and now its time for a new tank.

[NSR-Dan]

that sucks dude. you should dress your tank up ni leather like yourself. that might save it next time lol:blip:

[texmo]

Yeah pitty it ruptured at the seems on the other side from where I repaired it. Nead it is great shit fizzer

[Kornholio]

LOL, how did you predict that, two days before the event!!

Your spooky dude!

do de do do do de do do...............:doobey:

Yeh POR is good..... used it on my old bike, knew the guy that bought it and he had no problems and onsold it still not leaking about 6 years after I had origionally done the tank

you can get POR in Palmerston North look at http://www.por15.co.nz/

The best is tank replacement. Yet BNT (brake and trans) sell a fuel tank repair kit that works. Have used it and has lasted 2 years so far (can't find a tank yet)
with no leaks and thats off road and the boy's have dropped it a few times.
Once you have a new tank get it plastic coated by a radiator shop and it shouldn't rust out.

[vifferman]

The best option is to replace the tank.

If you opt to fix the tank (new piece welded in, or whatever), you'll still need to use the 3-part tank sealer stuff. I had the same problem with my VF500 - tiny pinholes that I soldered up, followed the instructions for the Kreem tank repair stuff implicitly, and it still kept leaking from the worst hole.

[Motu]

Kreem is too thick - I had the same problem with my XLV750 tank,I repaired as many as I could,but there were still a dozen or so leaks.Kreem didn't seal them all,So finished of with a coat of POR 15 and no more problems.POR 15 is thinner and gets into the holes better.Any goopy patch applied to the outside will ultimatly fail - you need to fix the hole and then use the tank liner.

[texmo]

So whats the name of this 3 pot stuff and where do I get it from?

[R6_kid]

POR 60 i think... do a search thru KB for it.

[R6_kid]

make that POR 15, lots of info here:
