Default Subaru EX13 fuel tank leak

Purchased a Manco American Challenger 126cc a few days ago and was going through it to get ready to run. Fuel tank and carb were full of water from sitting outside. When taking off the fuel tank I think I cracked one of the two studs holding on the tank. Now have it all back together and the tank is leaking in the corner above that stud. Is it possible that stud went all the way into the tank?? Could I drill it out and patch the tank as a temp fix? Anyone ever have this happen?

I’m gonna be like McKutzy and request pics. Very hard to diagnose issues without seeing the item.

EDIT—it surely sounds like you ruptured your gas tank though. You might try some JB Weld to patch the holes. And no, I’ve never done anything like that before. I’m very careful.

I’m a professional.

^^Yup.
But I do know what he's talking about, I've read about this in other places. The cheap Chinese made Honda clone gas tanks have a tendency to crack at the studs.
OP - You most likely have a crack at that stud, and you might be able to solder it to seal it up again(do it with an EMPTY tank!!).

Here are som pics. I already broke the stud the rest of the way off and center punched, but maybe solder might be worth a shot. The problem is these tanks have a jacket around them so itís very hard to find or see the actual leak.

Might be time to invest in a new gas tank regardless. Whatís the inside look like?

I found a manual with the part number(s): #276-60102-11, Fuel Tank Cp EX13 - Black

https://subarupower.com/wp-content/u...ex21-parts.pdf

Otherwise, this looks promising:

It’s pretty rusty inside. Unfortunately, I think a new tank is going to have to be the ultimate fix. Thanks guys

Good idea.
Once they get real rusty it's sometimes not worth the effort to save 'em.
Glad we could help!

Sorry sorry... was in a deep dark spirally hole of what is the Pinterest....... even still.. have a sick cat...

As always... if its cheaper to replace than fix... do so.... if not convenient to buy a new try and fix...

but as you said.. its a tight spot....

AND NO...DO NOT TRY TO WELD IT!!!!!

Umm, not welding.
Soldering, as in electronics.
A welder would blast a hole through that tank.

I'm not sure what time zone you're in McK but you're always on the clock as far as I'm concerned.

Don't slack off again, bub.
...and I always thought you were a dog person...

Ya.. its more of the woman's cat than mine.. but... its ours.....
Im on the west coast here of BC.. so I think thats a -7... so same as California Washington Oregon...

And as far as being here almost all day....Being laid off cause the darn factory closes a few months ago... Is sadly why Im quick on the draw...

JT
It could be welded...Just not easily, or safely...
Soldered yaaaahhh..... maybe... a shade better than the JB.. but ya have to have a bit of skill... Not a cheap plug in iron....need some high wattage or go ol' school copper....

Oh yes indeed. To effect any *quality* repair, you practically have to have mad skills, or everyday mundane skills if you lived in or grew up in 1950s suburban bliss. That’s long gone though. Parts replacement is the name of the game here and everyone knows it.

Anyhow, all is forgiven and my apologies for taking the hard line...

On the other hand, we could just let numskulls take over the forum and freely give out bad or wrong advice, “it’ll be fun”, especially knowing Sid and landuse has to clean it all up. Wait, Sid doesn’t actually have to, he just does.

Yeah, you need a vacation.
