Bad regulator on Lance??

2008 Lance 845 with dual tanks - got a bad propane regulator. Seems to be leaking, so will not repair, but I can't find the right one. Some of the "descriptions" make no sense, and don't want to buy the wrong one.

Not sure whether I want the stock regulator, as it's given me trouble before, and I'd rather buy good/better quality if available.

Can anyone give me a model number and a good quality regulator that will change directly, without modifications?

It's the dual tank automatic changeover, and horizontal tanks

Thanks M44
  • Of the several I have had, it doesn't seem like any were markedly better than any other.

    Personally I have had 2 Cavagna that came OEM on new RV's simply fall apart at the indicator assembly and have also changed 2 or 3 out for others that have done the same.

    I now swear by these MARSHALL HIGH FLOW 350K BTU
  • Took mine off(was leaking also)and took it to a local propane company-they had it in stock, so I bought a new one. Sorry I can't remember the price, but I do remember thinking "is that all it costs?" Oh, I have the horizontal tanks also. Gary
  • I never liked the changeover valves as they would discharge propane when I removed 2nd tank for refill.
    So now all my RV have one of the ports plug and I never use the changeover.
    Meaning I would not replace the combo and use single regulator only.
    Way cheaper and available everywhere.
    10 years old hose might get hard, so good time to get a new one.
  • Yup - ordered a new one today ... thanks for all that advised. Will replace hoses too ... got three, one is a BBQ connector - might just plug that one, as we've never used it, ever. Happy Camping to all in 2018 !!! Bill & Genie
  • I have never had a changeover valve leak propane with 1 bottle removed. in fact my 5th wheel uses 4 grill size bottles with 2 auto changeover valves. I can remove one tank to get it filled, and return 1 week later and no leaks.

    on my Wolf Creek it has one that looked like the Cavagna shown on amazon. I had it change over once but stay green. I had the refrigerator stocked for a trip. the morning before leaving I opened the refrigerator and it was 75 inside, both tanks were empty and valve was still green.

    I have the same valves on my Arctic Fox but its always turned red on failover.
    but after the Wolf Creek failure, I bought a Dometic LPGC10 LP Gas Checker and always know the level of the tanks

    My troubles were with Marshall when I switched to Cavagna. Maybe this high flow unit is better built.
