Re: Dual line tank o ring replacement
On some of these double line fittings, the brass hose nipples screwed in. It is just a matter of unscrewing the nipple, and everything comes out the back. If you have the fitting with cast in nipples, a simple way is to make up a small stiff wire hook, like a crotchet hook, and pull the O-ring out. Just be careful you don't scratch, or gouge the brass sealing surface. It is an easy matter to stuff the new ring back in. I replaced a lot of them this way.
