Air Intake ideas?

Here is a write up of the snorkel i had on the bus before

PARTS LIST
8 foot of 2" PVC tubing. (black or white)
One 90 degree elbow, white. (it has a coupler to mater to the 2' PVC, but the other end is the same size as the 2' PVC) One 90 degree elbow. (black or white)
One 60 degree elbow. (black or white)
Two Rubber Pipe Connector/Reducers. (2 inch to 1 1/2 inch reducer)
1 1/2 diameter swimming pool hose.
K&N filter #RV0680.
U-Bolts. Threaded stud. Wing nuts. Stainless steel clamps. Angle brackets. PVC Cement. RTV sealant.
My snorkel setup is different than most, since i did not have the original air cleaner for the engine. I had a 10 inch open element air filter.
1. First start by taking off the air cleaner.
2. Determine how to attach the White 90 degree elbow to the carb. The part of my application that made it succesfull for me was that my carb had a spacer plate on it that allowed me to snugly insert the white PVC elbow. If you are not lucky enough to have an adapter plate get a measurement carb diameter and search through the home improvement stores plumbing inventory and you should find something. A rubber connector is preffered, because you can stretch it and is is easier to clamp than hard PVC.
3. Cut a 5' inch piece of the PVC pipe and insert the cut piece into the elbow and aim the opening towards the side of the jeep where the snorkel is to exit.
4. Take off the Elbow and Drill a hole in the top of the 90 degree bend. This is where you will take the threaded stud from the carb up and through the elbow and wing nut, or bolt it tight.
5. If you are like me and have an early style CJ5 hood, then you can take off the plate in the hood that was made for the snorkel. But most likely you don't have the luxury so you will have to cut the hood. Cut where there is enough of the outside fender surface to support the snorkel. Also the cut will be from the bottom up, because when finished the snorkel will be hard mounted to the fender and the hood will close over top of it.
6. Take the Black 90 degree elbow and place it on the fender with one end into the engine compartment and the other pointing to the rear of the vehicle.
7. Cut a 7' piece of PVC tube and insert it into the elbow opening that is toward the engine comparment.
8. Position the elbow and tube to where you want it on the fender. Place the U-bolts over the pipe and mark where you will drill in the inner fender to mount the fender elbow assembly. Keep the U-bolts about 2 inches apart.
9. Drill the holes.
10. Take the U-bolts and loosely mount the PVC pipe to the inner fender. The U-bolts will have to be trimmed so that you don't stab the tires with them.
11. Now it is time for the creative part. The rest of the snorkel will have to be measured based on the vehicle and where the hole in the hood was cut. Cut another piece of PVC and insert it to the elbow assembly on the fender. Then attach the 60 degree bend and run another piece to the windshield. You will have to decide on how high you want to have the filter. Watch out for the doors when they open and close. You might have to twist the assembly to position it.
12. After you figure out where the snorkel will go then you can tighten the U-bolts.
13. Take one of the reducers and place it on the PVC tube on thecarb assembly.
14. Take the other Rubber reducer and place it on the fender elbow assembly.
15. Take the rubber pool hose and bring it next the rubber reducers and measue how much you will need to attach it. Do not run the opening to the carb and the opening to the fender assembly straight to each other. Turn the carb assembly about 10 - 15 degrees towards the front of the engine. This will give you an arc in the path between the assemblies. This will allow the hose to flex with the motor. This is real important to have a little slack in this flexible hose, because the snorkel could break if the hose isn't allowed to flex.
16. Cut the hose and insert it in the reducers. Then tighten.
17. Place K&N filter on top of snorkel and tighten.
18. You now have a snorkel. Welcome to the world of deep water.
Of course you are not done yet. After you have everything together take the joints apart and use PVC cement on the elbow assemblies. Some people don't use any sealant, but i will suggest to seal everything that may be a potential leak. The PVC cement is hard stuff and you may never be able to take the pieces apart after it dries, but the price of all the PVC parts are far cheaper than rebuilding a hydrolocked engine. And remember to get the snorkel part positioned right so that when the cement dries it will be in the correct position.
Other things I did not mention is to attach the snorkel to the windshield frame. I attached the snorkel to the KC light mount on my windshield frame. Attach it at least in two other places, this will keep the snorkel snug and prevent the trees from walking off with it when on the trail.
This snorkel was applied to a 225 Buick V6 with the stock Rochester carb. Any larger engine may require larger diameter tubing.

unfortunately i do not have any pics of it on the motor., the snorkel has been destroyed in a freak fireworks accident... the mortor round decided to stay in the elbow of th esnorkel and consequently it exploded into a million pieces Also it was installed on a V6 (rochester carb) so it may have to be modifyied a touch for an Fhead if you do it.
