Real Walbro

I wanted to buy a walbro 255 and this guy had it locally, but from the pics it doesn't look like a walbro (its black not silver and fatter). Anybody with more knowledge knows if this a real one? Thank you

The black thing you see is foam around the pump. It keeps vibration and noise down. It comes with the pump on 3SX too.

the top and bottom are a little different though?
