I've just changed out the fuel in my 50 gallon storage tank and began thinking of installing a desiccant breather. The ones I found were expensive and throw-away units. I wanted something I could recharge with desiccant pellets bought online. This is what I came up with:
1) I started with a Goldenrod fuel filter. I bought the cheapest one available and it was tapped for 1" pipe. They have a version tapped for 3/4" pipe.
2) My original plan was to drop a 1/4" fuel hose into the bowl of the filter - filled with desiccant - and use the 'IN' and 'OUT' tapped 1" pipe fittings. The problem with this approach is the center filter thread for the Goldenrod filter is a bolt thread: 1 1/8 - 12 NF-2A. The few tube/pipe fitting adapters I could find in this thread were quite expensive.
3) New plan: plug the 1" pipe 'IN' port and allow air to enter the desiccant vent through the pellets from the bowl's fuel drain. I attached the 'OUT' port of the desiccant vent to the fuel storage tank using 1/4" fuel line. I had already installed a roll-over vent in the fuel tank and it had a 5/16" hose barb on it.
4) I used a blue Scotch-Brite scrubbing pad (cut to fit) for a bottom of bowl filter and rolled up some Scotch-Brite and stuffed it in the 1 1/8 - 12NF threaded hole to filter that end of my vent.
5) There are no mounting holes for the Goldenrod fuel filter so I mounted the desiccant vent to the hold down straps for my fuel tank using a 4-1/2" hose strap covered in 3/8" braided nylon wire sleeving, a piece of thin chain, and a screwed chain link.
6) I expect it to work.....but only time will tell.
