Thanks to being the lucky recipient of a Safari Snorkel for my Birthday and many Christmases to come, I managed to get a Safari Snorkel fitted to the Landy last week.
The most intimidating bit for me was drilling the holes in the body work, making sure I had the template spot on etc.
On the existing induction pipe work, I sealed up the drain valve in the tee piece, for this I used Sika flex to seal the flap shut, then completely filled in the drain appeture with more of the stuff. I tested this when I finished by blocking the top of the Snorkel.
Once the holes were drilled, I fitted the neoprene gasket for the Snorkel to the body of the Snorkel using some Sika flex sealant, I also did the same with the windscreen mount gasket.
Once these were dry, I test fitted the lot with plain nuts rather than nylocs, so that I could find the location to drill the windscreen frame.
A lick of paint on the holes and then some more sealant around all the holes will keep the water out.
The windscreen mount is secured with self tappers, five in total. I left the bolts for the snorkel body on the windscreen mount loose, until I tightened up the wing securing bolts using nylocs.
The wing gasket had copious amounts of sealant around it, this is not really to keep water out of the snorkel though, more just to keep the holes sealed. The design of the Safari Snorkel is such that it does not depend on the wing seal. The whole upright section is continuos unit until the hose fits to it for the induction system, meaning that there are fewer potential failure failure points, that other designs.
