I originally built the snorkel by moving the stock airbox to the roof rack. I then used 3" flexible hose and 3" black PVC pipe to connect it to the carb. I just slipped the flex hose right over the opening of the carb and used a hose clamp to hold it. This was good enough to let me put in the air compressor. I then redid the setup.
After much searching I decided to use an air box from an '89 Mitsu Montero with the V-6 fuel-injected motor. It was the right size and had the intake and exhaust in the right places. Also Mitsubishi uses a lot of rubber hose in their vehicles that has the right diameter (approx. 3") to fit the PVC pipe and the top of the TLC carb. I used the tubes from a Montero and from a Mitsubishi van that looked similar to a newer VW. The montero tube went from the side of the air box (intake) to the black PVC pipe entering the engine compartment. I used the 90-dergree hose from the van to come off the top of the carb and connected it to a mystery 90-degree rubber hose I found in a '55 I bought for parts. I believe it came off a late '80s or early '90s Chrysler passenger car. I had to trim this part a little bit, too.
For the scoop, I originally tried to buy the ARB scoop but could not find anyone who would sell the scoop only. (What happens if you break your scoop and/or lose it? Will ARB not sell you a replacement?) Anyway, I decided I would just make a metal one and I had a sheet metal shop build one for under $50. I added the grate later. It came off the front of a Suzuki Slammeri. :-) I plan on piping my fuel pump breather holes, distributor, axles and transmission/transfer case into this system too. I want to be able to submerge the cruiser in water up to mid-windshield deep. (maybe a diesel conversion in the future) I hope this helps somebody, at least I had fune. :-)
