Question:

Have airstream w/two, thirty lb propane tanks. Have an auxiliary 100 lb tank I wish to connect marry to the system. Rather than connecting the 100 lb tank directly to the system regulator and having to disconnect one of the onboard thirty lb tanks I want to connect the 100 lb tank to the supply line of either onboard tank through either tank’s Acme fitting. Thus eliminates having to disconnect supply lines to the regulator each time the 100 lb tank is emptied. Simply disconnect from the Acme fitting. Please explain parts needed, pricing and directions for connecting. Need approx. eight foot of hose for supply from 100 lb tank to span from top of tank to underside of rv tank cover, back up to rv tanks.

We do have the parts to connect your 100 lb tank to your 30 lb tank and what you will need is simply the correct tee and then a hose; there isn't an 8 foot hose but there is a 12 foot hose that will work for you. The correct parts are the following:

- MB Sturgis Sturgi-Stay T-Fitting for Type 1 Valve - 1/4" FIF and Disposable Cylinder Ports # 103612-MBS

- MB Sturgis Sturgi-Stay Propane Fill Hose - POL Pigtail x 1/4" Male Inverted Flare - 12' # 100019-144

The T-fitting will go on your 30 lb tank before the regulator, and the supply hose will then go from the 100 lb tank to the T-fitting. The prices are on the respective product pages, or you can scroll down where they will be listed.
