P0445 / P1448 - Fried Evap vacuum cut valve - need part number

[neusal]

I recently pulled OBD II codes P0445 and P1448 on my 2001 Pathy. Fater consulting the FSM I did some basic troubleshooting and found that the Vacuum Cut Valve (Which sits in the Evap line between the Fuel tank and the Evap canister was melted and destroyed. I was confused about this until I remembered that I had taken my Pathy to a Hole-in-the-wall muffler shop to get a crack in my tail pipe welded. While the car was being fixed I remember that the guy had to pull out a fire extingusher at one point to put out a flame. I examined the spot where he said there was a small burn but couldn't find any damage. Anyway, turns out this was the valve on fire - not cool. Anyway, it seems liek a basic fix - but I need a part numebr so I can order it. Anyone know how to find this part number for me? Or tell me where i can get it?I would love some help!
