The pressure/vac hose seems to be missing when I got the stove. Both cables are connected but I can't locate the tubing nor the space where the tubing connects to the actual stove. This an older p61 (with the micro switch) that I have been trying to bring back to life and I have no history on it. When I bypass the psi switch by using a jumper the stove operates "as it should" on the test mode. If anyone would happen to know where the vac hose goes that would be great. I've spent over 2 hrs trying to locate it and the only thing I found is what appears to be a solid plug with nothing hooked up which would make no sense to do that and still have the psi switch wired. I tried to show that in the pictures. Any help would be greatly appreciated. I also looked on YouTube and got nowhere.

What is the test date on it, I might be able to help
 
Ok same as mine, I’ll have photos for you soon
 
Pretty hard to get a good photo of mine but hopefully it helps, and if it comes down to it I’ll move some things around by my stove so I can get a useable photo

I looked all over the fresh air makeup area and nothing. I found that one out of three bolts holding the combustion motor is missing....maybe it goes there but that doesn't make sense as well. I'm stunned.
 
Here’s another photo, I felt the vac hose and where it attaches, it’s down to the left of the switch and the nipple maybe broken off on yours

here’s another photo I found and you can see where the vacuum line attaches to the stove, doesn’t look like there’s a nipple, and like mine it looks to be siliconed into the stove. I’ve never had mine off so can’t say definitely

Hi again and thank so much for taking your time. You are correct. I found it and there is no nipple but it seems like the tube is just stuffed in there with silicone around it. Not sure if that was done originally but I will try to drill the remaining tube out and get creative. Thank you again!

Not a problem, keep the updates and photos coming…and it looks like that’s how the hose attaches in every photo I’ve come across
 
Got the piece of tubing to go through as I couldn't get it out. No signs of the nipple but it had silicone all over the area. I will post another pic when I get the tubing. Thank you again!!!
