Found when switching propane co.w/pic.

I switched to a new gas company and the gentelmen that was installing their new propane tank found this flare nut cracked when doing his inspection. He said this nut has been leaking gas for long time as the crack has a black discoloration around it.
Maybe my fuel consumption will go down? Time will tell. Wouldn’t be a bad idea to check them now and then
You think I should give Ferrell this nut back?
Is part of their Equipment?
Just my 2-cent. Take Care Mike

I work for small Mom and Pop propane company and the smartest thing you can do is have a leak check done. It's the check where they put a gauge on the line bleed it down to 10 psi and leave it set for 4 minutes. If you have a leak, pressure will slowly go down. Next open your hood once in a while in the summer and if you have a lot of flies under the hood you have a leak. Common areas for a leak that the leak check wont find is on the tank gauge next to the four screws and shut off valve, once in a while the tank it's self will leak and then they get to replace it.

Good luck Merle

I don't even HAVE propane, but just from surfing this site I've learned that they are an awful company to deal with.
