Pin holed petrol tank

[winchman]

Yes I have bought another motor bike.
The petrol tank has several pin holes on the top so would Belzona seal them? Remember I am tight so no expensive products please

Clean it up, gently tap the holes low, tin it and solder/lead wipe.

^^^ But not with a "blowlamp" Use a large copper bit tinmans type soldering iron !

When you tap hope you dont find further holes

id do the above clean tap the holes in. a bit flux and solder id also sandblast the tank anything that is real thin will soon go through and show up

Belzona is about the most expensive stuff you could chose. I have used Plastic Padding "Leak Fix" also Araldite epoxy, but did a Honda a couple of weeks ago with solder. Use Bakers flux or equiv, electricians flux is no good for steel and, for best results, float a copper or brass patch over, not pretty though.

I fixed the oil tank of the hand pump on my trailer by brazing. It had pin holes where it had rusted through. It was quite thick steel so it may be too much heat for a petrol tank

I know a man who will lend me his pot of Belzona

When my VFR decided to spring a pin hole leak in the bottom at work I sealed it with "Leak Fix", was still sealing well 18months later when I picked up a better tank to replace it!

One of the best methods is solder but it helps a lot if you use tinning butter.
This is a tank modification I did last year. The recessed area was filled in . The gray stuff is the tinning butter which you melt with a soft flame and solder over the top

Petropatch? Won’t be pretty but it works, If you can find some

Ethanol in petrol will eat any fibreglass product. Line the tank with Caswell or Por15.

I soldered up my tank. I either forgot to rinse it or did rinse it but should have also neutralised the flux as well. The flux caused a lot more rust, subsequently clogged up the fuel filter and caused a breakdown on a dual carriage way.

Anyway, soldering works great just be sure to neutralise the tank after with bicarbonate or something.

I used a large soldering iron, CPC do them for £15.

That is what I did to my old bike - permanent repair

Of course you don't use power tools to remove excess lead - hand tools only.

I've welded them successfully but you must clean them out very very well, I've also blown one up which I didn't clean out very very well as I was rushing it didn't help that it was a hinged filler cap that had closed, I changed shape in an instant

Thanks all its a good tip re soldering iron as it can be difficult to remove all the fumes.
