Rust inside gas tank...ugh
« on: May 17, 2018, 08:44:16 AM »

Okay...

So I have a new gas tank - painted by Andrew Swenson, so I'd REALLY like to NOT harm the paint - and looking inside it, there's some rust inside...

I used WD40 to wipe the inside of the tank and most of it was just a light surface coating - but there are some spots where I can still see a little rust. The almighty experts on the interwebz have two schools of thought (1) it's okay, just send it and (2) it's NOT okay and I need to remove it.

Kerosene and some sort of of aggregate in the tank is one solution that I've seen. I don't have a fuel pump or fuel cap on the tank, though, so it may be a little tricky.

Another is naval jelly. Never used the stuff but it seems like an option since it works quickly and doesn't run all over the place.

Anyone have any experience with this sort of thing? Suggestions?

Also seeing some folks are using vinegar - so I'm assuming the acetic acid is what's "eating" the rust away..........

Jim at max speed cycles told me how he deals with this problem a few years ago. Something along the lines of a manual media blasting only on the inside. When he told me how he did it I remember thinking "if I had to do all that i would pay him to do it!".

I'd send it.

You could treat it or use a safe remover.

$23 vs cost of fuel pump or worse valve seats. You are going to need to clean it real good when you cut the basket out of filler neck anyway.

Evaporust - watched a few vids on this stuff and it seems like a worthwhile solution to my problem...

There are really only a couple of spots inside the tank that have rust on them - so I wouldn't have to fill it to the brim to make this work.

To be continued - I'll install the fuel filler cap and hopefully it'll be water-tight enough to keep the stuff in there upside down while it soaks. Although...the vids I watch showed that it was not harmful to paint. Science is pretty cool...lol.

It will not be water tight with the cap. R6 tank the base opening is big you can get your arm inside the tank I would use a little elbow grease or I had one tank we used this on

Never had an issue with the tank until the person I sold the bike to got ahold of it. Then rust was the least of its worries.

How bad is this rust?  light surface rust or like flaking off rust?  Workshop hero Metal Rescue will remove the rust without hurting the paint, or rubber or plastic.  You can pour it in the tank and let it sit overnight and the drain it out and rinse the tank.  The stuff is reusable and it really does work.  And it really DOES NOT hurt paint or emblems or anything.  It can be had online or from your local motorcycle shop that deals with Tucker Rocky.  Comes in one gallon or 5 gallon containers.  Retail for 5 gallons is about $135.00.  Kinda pricey but it works as advertised.

It's light surface rust - nothing too bad. It shouldn't take too much to get it where it needs to be...

So, I'm now curious about all the recommendations to 'send it'..
Apologies for the ignorance but - Send it where, and to whom?  :confused:

Shetty, Lesley said the same thing, lol. It's one of those millennial phrases. I think it means "go for it without regard to the consequences". :D

You are not alone.  :dunno:

I just assumed it was an autocorrect goof and people were just poking a bit, and I gave up trying to figure it out. Either that or it’s some new usage, like “I have this bike for sell” :)

Or it’s a copy/paste thing and in the original context the writer meant send it off to be painted and nobody caught that Shane’s tank is already painted and so failed to respond with a wtf.

Or...

And this is why we gave up trying. Wait, I gave up. You actually asked. Good on ya, mate.
