Sniffer part number

Would appreciate some help locating the appropriate sniffer for my 87 gv.  Would like to keep original brand type if possible. Some of you know it is  brownish in color. Has three wires, 2 red and 1 white. Thank you in advance

the new ones I have found are all smaller faceplate, so you may have to make a faceplate adapter.  Also most of the newer ones don't have the capability to operate your gas solenoid valve.  So chose carefully.

Long time ago, so memory may be incorrect, but those old brown ones I believe were made by CCI.  Been out of business for a long time.

So, yes, likely you will buy one of the newer generation ones, make a face plate to mount it and remove the solenoid valve.  You could search for one that still controls a solenoid valve, but very few newer coaches have the solenoid valve anyway.

And the new ones do "time out" after a few years. They even make a sound to let you know it is time to replace them

Thanks everyone for your contribution. From what I have learned, it looks like I will just do away with the solenoid. It took some time to learn all this, I was bent on fixing the solenoid not knowing it was not even needed.

Yup, ours went out a while ago, and we found a new one that fit the face plate that Brett made.  ^.^d  P.S. there is a fuse behind the 'sniffer' that will have to be pulled before any work (or waxing) is done. It's easy to test, just spill a small amount of whiskey on the floor, you'll find out!

Black plastic and walnut seem to mix well. Or get some inexpensive luam, and use some Howards feed-n-wax on it to make it purty and match well.
BTW EVERY new owner should try Howard's on there woodwork, looks amazing.

Bob,

I replaced the CCI model 7719 with a Safe-T-Alert 70-742-P-R-BR-Kit from MTI. 70-742-P-R-BR-KIT MTI Industry Gas Leak Detector Shut Off Kit LP And CO Gas

The new one has a solenoid that gets a continuous 12 volts and stays warm to the touch.  It takes about 10 minutes to reset the alarm but the solenoid is on as soon as there is power.  The detector is a 4 wire instead of three and you have to add a ground to the chassis or the negative post on the battery.  I got lucky and was able to find a good chassis ground for the black wire on one of the floor bolts underneath the drawer in the kitchen right next to the detector!  The yellow wire from goes to one of the white wires on the detector.  I connected the two red wires to the one red and the other white wire from the detector for the other connection. Using wing connectors makes it easy to remove.

I also replaced the twin site sender IP5628S02537 on the tank from Gas Equipment Company.  Gas Equipment Company  It's 0-90 Ohms and is an exact replacement.

It works perfect on the tank and with the Audit 860.  My old one was cracked and needed replacement. 

On mine I had to enlarge the hole a little for the new Safe-T-Alert to fit.  I also used winged wire nuts for the connections inside,  About $250 for everything.  They should be changed every 5 years and the Safe-T- Alert will give an end of life reading. 

I also changed out the old Marshall 260 propane regulator for a Marshall MEGR 291 which I should have done when I replaced the propane detector. MEGR-291 Marshall Excelsior Propane Regulator 1/4 Inch FNPT Inlet x 3/8 Inch...

I didn't check the pressure before installing but all my gas appliances are working much better. 

I'm not sure when the regulator should be changed ( I believe at least every 10 years ) but I know the furnaces are very sensitive to gas pressure.  I have a two year old Atwood helium fridge and it was starting to take a few tries to light the burner.  Now the proper gas pressure 11" WC comes up much quicker when the main valve is turned on and the fridge lights on the first attempt.

I had to remove one of the old fittings between the main valve and the old regulator to make room for the new larger regulator but was able to use the original bracket.
