LP Leak Down Guage


New Member
I recently discovered 4 high-pressure LP leaks between the vapor valve and the regulator on our Alegro Bus. Pipe dope had dried...not a good thing! On our previous motorhome there was a low pressure LP gauge located behind the refrigerator (outside access) and mounted in-line with the gas line. It had a rotating bezel with a red needle that could be set to match the gauge needle. It was great for leakdown testing of the LP system. (Turn off all LP appliances, set the red needle, turn off the main valve at the tank and check for a drop in pressure...the red needle made it easy at it did not move). This was great! Always there, always ready if a leak was suspected or just for preventitive maintenance.

Here's my problem, I have been unable to find one of these gauges. About 10 years ago I seen one at a RV parts store for $6. I would appreciate any help in locating one of these guages, or info on alternative gauges that would be appropriate. Thanks! :)

Found what you are wanting in a Winnebago parts book P.N. 065741-01-000 .Now I'm not sure if you would have to order it from Winnebago or if you can get it from a dealership.
Hope this helps.

I found one that threads onto a new cylinder with the acme threads. It won't go in-line like you are looking for. Glad someone else found it.

Thanks to both of you for your input. I was unable to locate anything via the part number. However, I emailed Winnebage Parts, described the gauge and included the part number. I really hope this comes through as it is a very quick and simple test of your low pressure LP system. Thanks again!
Happy Holidays!

I have followed the leads and no one has the gauge. I'm sure there's a Winniebago scrap yard somewhere! Still looking for help. Thanks to all...

Sorry, the part # that I posted for the gauge was from a 1999 winnebago/Itasca parts book that came with my 99 Itasca. I figured they would still carry them.
