My apologies. I know there are a # of posts about the regulator. I hv the spare Marshall to replace my original. Can’t seem to find directions to do so on the site. Camping in the high altitude mountains of nev/Cali and continue to get a whiff of propane on the frig side outside. Can’t think what else would cause it. If you have the site help from links that hv given directions please refer them my way. I have some tools w me but maybe not enough. Thank you
