Installing a gas pressure regulator
I called MB Sturgis and they said to use either Loc-Tite or regular thread tape.
I asked if it should be a tape or dope that is propane resistant and they said no.

I'm confused.
I always thought that I needed a gas resistant thread sealer.

The only real difference between the white and yellow tape is the thickness (the yellow is twice as thick). Technically, you could use either one but I would use the yellow, if using tape.

If this is more of a permanent installation, I would use pipe dope (YMMV). This link may be helpful:

I recently had a secondary regulator installed to feed my BBQ Grill. The work was done by a tech at a bulk propane dealership. He used pipe dope on all connections.   ;)

Thank you.
I had difficulty removing the old one did I'm going to have the rest done by a professional.
A brass nipple broke and fittings are stuck.
I don't feel comfortable wrenching that hard on that tank valve area.

UPDATE:

I realized it's left-hand threads into the tank which makes sense now. Doh!  :-*

I need a shorter line since I'm removing the external tank adapter.

Will a short flex line work?
Can I get those at Lowe's or HD?

This is the solid line I removed. I need a line about 2 inches shorter:

Hi Ted; I would avoid a flex line, especially on a moving vehicle. You could cut off two inches and put a new fitting on one end. Are those compression or flare fittings?  You could cut out the appropriate amount of tube in the middle and re-join it with a  compression union, to retain the present fittings if they are flare. (Leak check after installation required!).     RonB

Yes. They are flared.

Hi Ted;  To save you some money, if you decide to re-do a flare fitting on a shorter tube; I once bought a 'cheap' flare tool because I only needed to do four fittings. What a waste of time and fittings! I bought a Rigid brand flare tool. It did an excellent job. That was about 25 years ago, and I've never used the tool again!. But it was worth it anyway, even if just for the education.

Hello, look up the company Hose Pros. They can make a custom hose the lenth you need. Hopefully they are still in business.

All in.
Soapy water test good.
Appliances fire up better.
Frig lit right away but I need to test longer.

I cut the pipe shorter and flared II.

Thanks for the help!

So far so good.
It even has a better sound when it fires up.

Ran it all night on LP.

Top shelf temp is 34° at the number 3 setting.
Bottom shelf is at 38°.

I think it's a success!!

"Top shelf temp is 34° at the number 3 setting."

I'm curious over your curious wording... are these temperatures inside the box or the freezer?

Seems to me if it's the freezer it should be somewhere much closer to zero °.   ::)

Get a bottle of decent champagne or spumante and chill it in the fridge to reap your reward!

Those readings are from the frig not the freezer.
I used two thermometers.

"I used two thermometers."

I've used a variety of thermometers over the years but since 2017 I have been using the one in the following link. I mounted the monitor panel at eye level on the wall just to the right of he fridge door so that it is quite easy to see. My readings are a consistent 34° in the box and a -3° in the freezer, and I don't have to open the doors to know that. One of my better purchases.
