Homemade Snorkel

by Alan E. Foster

I based my snorkel design upon that of Greg Haugen, due to it's simplicity and ease of execution, but also for it's simple reliability.

The supplies which I used were:

Silicone sealant
Countless lengths of intake hose (cursed store only had it in 22" lengths)
2" ABS pipe
4" ABS cap
90 degree ABS connector
Black rubberize-it compound
Hardware cloth
Six square-drive, auger-tip lubricated screws
Assorted zip ties and pipe clamps
ABS cement

My first step was to cut the flare off of the intake trumpet.  I then filed it smooth, and attached a piece of the intake hosing using the silicone.  Also at this time, I went on and joined two more pieces of the hosing to the first, using short pieces of ABS as connectors, securing them with silicone.  (This took lots of silicone, mind you)

I then measured a template to use to fit the hardware cloth inside the cap, which is to keep wee-beasties, etc., out.  This I did by simply cutting a piece of cardboard which matched the inside diameter of the cap, and then cut a square of the hardware fabric to match (square so I'd have some extra to work with) and bent it to fit inside snugly.  I then cut a circle out of the center through which to put the shaft of the upper snorkel.  Once I had tested for fit, I used three of the screws to hold the fabric in place in the cap, and three more to secure the cap to the shaft, being sure to leave more than an inch for it to get adequate air.  The lubricated auger tip screws meant I didn't have to pre-drill the holes, which was very nice
considering that I was securing round objects.

I then cut a hole in the plastic cover which fits on the top of the driver's side fender using tin-snips and a file, which turned out better than I had anticipated.  Once this was done, I ran a piece of the intake hosing from the shaft of the upper snorkel to the piece which would lay along the hood (horizontal), and secured them together.  At the same time, I attached the 90 degree elbow to the horizontal, and fit it down through the plastic cover.  All that remained was to connect the hosing under the hood to the elbow, which was accomplished with yet more of that gooey wonder, silicone glue.

To secure the upper shaft in place, I used the hose clamps (4" size, 3's don't have enough thread) and a few zip ties which went through small holes drilled into the upper shaft to connect it to the roll bar.  The final step was to secure the horizontal to the plastic cover with a few zip ties, and to coat the silicone joints with black rubberize-it, mostly for looks, but also as a safety net to make sure the joins were water tight.  I think the final product looks good! (and it works, too)
