what is the part that is circled in green ? I know what it is and i know what it does i am just lost as what it is called . i need a replacement .the push pull connector? [IMG][/IMG]

 

what is the regulator for? what size hose goes into the fitting? it looks like a pushlock fitting to me, but i'm not sure what that reg is for. you will also need to know what the thread is. just take the old one to a welding supply shop and they should be able to hook you up.

 

thanks
