Gas tank rust and pin hole fix?..

[BRONX INTRUDER]

So I was using a sander to prep for repainting and a bubble formed on underside of tank. Wiped bubble away and a pin sized hole is there. Vibes musta made way for leak in a weak spot due to rust inside.

Anyways.. What have you used to seal inside of tank and i've seen youtube videos of soldering the hole.. Anyone else done it?

I'd post a pic but back in the day it was imageshack that I used.. Dunno what to use these days. Lol.

From what I understand , folks have had good luck with POR-15 fuel tank sealer.
Depending on the size of the hole...usually a pinhole will turn into many pin holes.

To be sure, Navigator. If there is one pin hole,...there are others. Hidden right now perhaps,...but there to appear later.

Later,...AFTER you have spent Good Time and Money painting the tank. POR-15 will seal the tank, but not prevent the progression of the existing rust between it and the Weather outside. Even if you address the rust around the Pin Hole you now see.

Don't ask me how I know this.

Many companies also make a rust converter which when used inside will chemically convert the rust to a hard black primer type coating.
That in addition to the POR-15 may slow down the inevitable.

But as Neil Young aptly states: Rust Never Sleeps.

There are a few liner kits out there - lots of people rate POR15 but there's no love for the KREEM kits.

But the key to being succesful long term with sealer is removing ALL the rust before any sealing.

I've soldered some pin holes in the past but it was only for fast jobs. Wire wheeled off the surface to expose bare metal then used a big iron and a lot of flux. Helps to keep the area where you're working horizontal

Hopefully its not a 98 VS1400 with a hole?

Thanks brother; pic added.
No.. Lol.. She's fine. It's my Red one which I believe is a 97.

I wonder if the converters are fluid enough to swish around inside and get out remainder before doing a por15 seal..

Thanks for the soldering tips. Lol.
How about removing all the rust?. Dog choker chain on a rope and let it slide and rattle around as I violently shake the tank? Lol

I used this method to knock off the major portion of the Inside Tank Rust. However, this will not get out the rust that is in the teeny-tiny ( pinhole sized and smaller) recesses. To be that thorough, you'd need to Sand/Wire brush the metal.

I used a 24 inch long Sash Chain ( used for replacing Sash Cords on old Double-hung Windows ) Because it has squared-off links, not round-wire,... that have sharp wedges everywhere.

And I put the Tank in a Fluffy Quit and stuck it in my Clothes Dryer ( on Air only) for an hour or two to fully scrape the inside Tank Walls.

Worked like a charm.

Kool beans.. I'll look into it.

Word of caution. If you are going to use the rust converter you need to fix the pinholes first or the heat of soldering will destroy the rust converter.

Most tanks are pretty hard to get totally rust free / clean due to the fact they have limited access points (IE: a filler and fuel tap / gauge hole).

I've used electrolysis on some tanks and it works OK but you need to get the electrode right inside the tank where the rust is for it to work properly.

Depending on how far you want to go you can cut out the tunnel - then repair the rust and weld it back in. Sounds pretty crazy but if you are dealing with a tank that you can't replace it sometimes ends up being the best option. I did that with a ZX11 tank once. Lot of work but it was only my time as it wasn't for a customer.

Perhaps it might be there. It is an item that is used to replace the Sash Balance Weight Cords in the Older Homes (built before about 1950).

Since you live in an area that has Housing Stock of that vintage, you might find it at your local ACE hardware store instead.

After you use the Dryer to turn it over and over, to get the fine Rust Dust out I suggest you use a Vacuum Cleaner and put it in the Gas Filler Hole and shake tank a bit. then put the Vacuum Cleaner on Blow and push the dust out the Fuel Outlet Hole. Do this several times.

And then use the Product Navigator mentioned that "changes" rust to take care of the tiny amount of rust in The Seams and any Roughened Surfaces the Chain couldn't get to scrape over deep enough.

[hillsy]

Putting abrasives in the tank and agitating is fine for most parts but it won't remove rust from the seam areas - you need a chemical or electrolysis to get in there.

All good suggestions though.

Thanks for all the tips and info brothers.
