Nick, Just curious. Did you ever contact Gillig to see if they had the pump?

The system must have enough leaks that the cut-off switch never completely cuts off the pump. I am wondering about installing a manual switch in the dash to cut the pump off when I'm not trying to operate the doors.

I missed this earlier. The problem with a manual switch is that the doors will go to the "home" (spring-loaded) position when vacuum drops, so you'd have to flip the switch periodically.

My system holds vacuum for several days (after replacing a couple of lines), so I ordered this switch to minimize wear on the pump. BTW, mine's the same as yours.

and paid about the same. Has worked fine.

Company is SCSFrigette; the Motorhome Magazine site is now worthless for useful links, but this is a direct link.

Here's the label on the pump I bought from SCSFrigette

Okay I have removed the old venturi generator and have ordered and already received the replacement pump. It is exactly like the one pictured by Ed. I need to put a switch so it does not run all the time. The link above takes me to a place called evparts.com. The listing is for new parts $1400 to $4600 parts. I am betting they are not the ones I want Any more help on what the switch is you are talking about so I can get one. I need the heat working for this fall hunting season. Also how do I wire it in when I get it?

Okay I dug in further in the evparts site searching vacuum switch and found it they also say I need a relay and have a nice wiring diagram. When the rest of the parts get here we will see what we can make happen. Nick has it been working well for you?
