ok so upon further investigation I have discovered my setup is designed to be on the high pressure side which isn't a problem except that when I talked to my local dealer he told me the current fittings I have are no longer legal here in Canada and he would not install them, and recommended I not install them. He did recommend placing an add-a-t adapter on my tank and buying a new adapter hose.
I'm not happy with these answers so I'm wondering if anyone knows of a supplier who sells the 1"-20 fittings with 1/4"mpt male and female fittings on them. My plan is to take one of the tank pigtails off the regulator attach it to my 1/4" mpt cross with 2 females across from each other and 2 male 1/4"mpt nipples and reattach the pigtal/cross back to the regulator then add 2X1"-20 male fittings to the cross and take my quick connect male nipples off the hoses leaving 1/4" mpt's that can now be adapted to 1-20 females. I have been searching via google for 1/4"mpt-1-20 fittings and have found several crimp on but no 1/4"mpt fittings. does this seem like a plausible option and do you have any suggestions for supply.
thanks
