Anybody out there suffered from poor gas pressure linked to the new style locker mounted gas regulators? I have after buying my 2010 Moonstone and changing from propane to butane. New pigtail hose used for around an hour in total. Worked in August, goosed in September.
A few people I know have had problems with the mounted regulators. It seems if the regulator is not positioned higher than the gas bottle the reg gets oiled up and fails. Hope this helps.
------------- live for today as tomorrow ma never come.
Everything is as they say it should be but still the problem is there. I can't see oil leaching from a brand new pipe within an hours use and the pipe was hanging free for three weeks allowing any residue to drain off. I don't think they are revealing the real problem.
Bit odd this, first I wondering how an hour is long enough for oil to get into the regulator, work it's way too and then swell the rubber diaphragm?
Also and although not unknown, it's propane not butane that causes the vast amount of problems, this due to the far higher pressure inside propane bottles.
Where you are right is with the hose, this has never had anything to do with it, raising the reg itself while possibly helping has now been proven to be well short of a cure.
I'm left wondering how you handled the new bottle prior to fitting?
Put another way, the bottle should be transported up right with the minimum of shaking about, preferably then left to stand before connection and turning on, turning on in itself as slowly as possible to minimise any rush of gas up to the regulator.
In the case of propane and before connection, the bottle gas tap should be quickly opened and shut a couple of times to remove anything trapped behind the tap, using a paper towel over the outlet while doing this will catch and show the presence of any oil in the gas flow.
I have had a regulator fail due to the oil contamination. I changed my regulator and got a SS hose. To date I still believe its the flexible rubber hoses that are the issue and not the Gas.
I removed my SS yesterday as we are changing our van next weekend, and its bone dry. Where as when my reg failed. I must of got about a tablespoon of oil out of just the hose.
I know I have had this discussion with Gary before ;)
Bottle was transported in place from the dealership, new butane hose and gas tap fitted in place of propane hose, stood unconnected overnight worked fine for the two breakfasts that weekend. Kept in storage on site, three weeks later low pressure on hook up. Can't get my head around how quickly it happened, don't use gas much, last bottle lasted two years. Didn't open and close gas tap, will try that next time and after I've changed the regulator. Maybe I should just stop having fry-ups. Thanks all for the advice.

Al well and good but, one experience does not prove anything.
When this problm first arose, I'd already been seeing and dealing with this 'oil' for a number of years, all then with bottle mounted regs, the problem then was further down the system, ie, Cascade burner modules and blocked gas valves.
I'd seen dozens of these and already on the case of why when post 2003 the problem of bulkhead mounted regs reared it's ugly head, to me it was just a different result to the same on going problem.
When the NCC report came out,my decision was to say no more on the matter, knowing full well the conclusions were comical and the solutions proposed would not work in the long run, this has proven to be the case.
What I'm fairly sure is the cause is sloppy cleaning or infact not cleaning bottles internally after periodic pressure testing using a oil like fluid containing a yellow dye.
To my mind this fits very well as the problem comes and goes and we are now in a blip which suggests to me a great deal of bottles have been tested earlier this year.
Once this lot settles down we will once again see a decline, and another blip in a few years.
If on the other hand the hose was at fault, first it would be constant and a darn sight more than 4% involved, and second, if as you say such a large amount has been removed from the hose, (far more actually than it contains!), then the hose would be so brittle it would snap!!

As regards this particular blockage, the more I think about it and given the reply to my questions, the more I believe the problem was already there slowly swelling the diaphragm, fitting the butane and new hose then being a pure coincidence!
