Propane gas regulator

'77 Gillig with 855 Cummins big cam 2 stroke and 5 speed.
Can someone point me to a good quality 2 stage high flow propane regulator that can handle a 6300 watt generator, a stove/oven and a gas refrigerator. I am terribly ignorant about propane regulators even after reading some tutorials I don't quite trust.
Now here's where I really reveal my ignorance. Ordinary air compressor hose is rated for 250 pounds and has crimped 1/4" pipe fittings. Is there a reason other than legal this stuff wouldn't work for propane hose? See, I told you I was ignorant.

air hose has a relatively short shelf life - for propane you don't want the hoses to be rotting away - I have racks of air hose and paint hose that can't be used anymore because the rubber lining is coming loose - can't even use it for painting - the only reason I haven't thrown it out already is I haven't got around to saving the reusable fittings yet

I definitely wouldn't use hose that's not specifically rated for propane. There are plenty of companies that sell generator propane conversion kits.

I agree.....

Propane has the potential to kill you and your family....... Take it seriously....

Use only materials approved for propane. Learn proper installation practices or hire a professional.

Get as wild and crazy as you want with plumbing, paint, layout whatever...... Electrical and propane are a different story. Do it by the book or find a pro to help.

As to regulator choice, I would check with your generator vendor and get specific requirements from them. I did a little Google-Fu and did not find any clear answers.

Regarding your engine? Is it a Cummings four stroke or a Detroit two stroke? Both were available in the Gillig.

The Gillig engine

Neither. It is The Cummins 855 Big Cam. In line 6, turbocharged 2 stroke, lying on it's side, mounted up front. I still haven't gotten to take it down the road because the tires are garbage and I'm still shopping for those. Another area where I have limited knowledge. With that huge, freshly built engine that, after sitting for almost 4 years, cranked for one second and started and ran strongly, I expect I'm not going to have any problem on hills.

Wow!

I would love to see that. Quite the unicorn.

down side

The down side is there is little access to anything underneath. This bus begs for an old fashioned pit to park it over. The upside is the power and the incredible amount of storage space in the "trunk". It is quite a cavern.

Ten best and worst diesel engines.

I think my top 10 would be a bit different. I would have to have one or two DD two strokes on the list. The big Cam 855 Cummins made #2.

OK.... Now I am annoyed......


Not only did they not consider the two strokes in the "top" motors, they called them "worst".

I missed that when I first read it.
