Stihl FS80 with tank pinholes fuel sprays out - pressure in tank?

[777funk]

Not sure if this is normal but I just picked up an FS81 and I noticed that there are pinholes in the tank. It'll leak if I hold it in the right position but when running I actually get a mist spraying like there's pressure built in the tank. I assume this isn't normal right?

The engine runs great and I have it adjusted to just barely 4 stroke at WOT under load.

anyone know if there should be pressure in the tank.

Spraying gas is not normal. And yes, there will be pressure in the tank.

I figured the pinholes are not normal, but I was suspicious about the pressure. Glad to hear that's ok. I'll fix the tank.
