From the photos, I can't be sure which nipple, of several, is the broken one. However, have a look at the photos in https://www.subaruoutback.org/threa...ck.org/threads/whats-inside-fuel-tank-edition-leaking-fuel-tank-autopsy.510193/

I suspect the nipple that's broken might be the one with the arrow, which the OP indicates is connected to the tank pressure sensor (and was also rusted off in that case).

 

Just get a new tank. They aren't much and can be swapped in about an hour or so. Replace hoses while it's down.

 

^^^This. It can be repaired with a new nipple silver soldered on. The cost to repair out ways the cost of a new tank.

 

Thanks all. Any good links on dropping the tank? My mechanic thought the whole suspension needed to come out.

 

It's not difficult and no the rear carrier doesn't come out.

Sent you a PM for the FSM since your mechanic doesn't seem to have access to anything.

 

Here is the gas tank evap line fix l did. Forgot to take a picture of the final solution but here is the story.

the evap line closest to the passenger side of the car had the nipple break off. It was a clean break with a clean hole back into the tank. The internal part of the nipple and I assume the hose remained in place.

in the pictures below you can see where it broke off and the fix I did.

i bought a 3/8" nipple and hose along with a piece of copper to slide into the nipple. I had to open up the hole in the nipple a couple of thousandths to get the copper pipe to fit in. I cut one end of the nipple off so it left a wider flat for the new connection to press against the tank and seal. I pushed the copper pipe into the the nipple leaving enough hanging out the end to slide into the hole in the tank. The copper needed to be filed down just a bit to slip into the hole. I put some JB weld around the copper pipe and slid it into the hole and then reconnected the new hose to the old line leading up to the tank.

Waiting to see if it throws any codes again. Prior to this attempt I had PO457, 451, and 442.
