Sorry if this is not applicable as I have not seen the Vans trays, but I had trays on my first IV that made carb maintenance almost impossible. They were mounted under the sockets so removing them for maintenance was not practical. This time I did something different. A picture is in my IV-1200 album. Out of town or would give a link to the photo.

Lowell- I added a photo of your drip tray.
Hope it's the one you mentioned.

I find my muffler does a fine job of catching drips. ;-)

G`morning guys
I have routed the "overflow tubes" into the K&N filters for the 3 years. Seems to work fine and does prevent fuel spilling.
I also made up "heat deflectors" that simply snap tie beneath the carbs. This seems to keep the carb bowls cooler after shut down on hot days. (first pic in my album under brush brackets)
The shields are made up from race car starter protector kits.
This system may not look very professional but is very easy to remove for maintenance.
Cheers
Don
This discussion is interesting to me. I know that many guys do route the tubes into the air filters. I think that Rotax says that the tubes must be continually sloping downhill, & that can be accomplished with the air filter set-up. I do wonder if the tubes had to do their job, and an air filter became soaked with fuel, if that could be a potential hazard. Do Rotax engines have any propensity to backfire?

Highwing, those cups look a lot like the spit cups in my dentist's office.
Unfortunately I don't have a photo......but, our kitfox is set up with the Rotax airbox which incorporates shallow trays under the carbs......these are different than the ones Highwing mentioned which are bolted through the sockets. The ones on the airbox are in the way for taking off the float bowl also; but, there are two small screws and they aren't much of an issue to remove so the drip pans can be moved out of the way to get at the float bowls The airbox has nipples on the top where the carb vent tubes go; and there is a nipple on each side of the bottom of the airbox for drain tubes which go down below the firewall.....the drip trays with the airbox also have drain nipples so I have a cluster of 4 drain tubes going down the firewall.
The airbox isn't cheap; but, it has all the fittings for all the vents and drains plus the drip tray.

…and won't fit on a I-IV without extensive modifications to the FWF.
Funny you should mention dentist's office as I spent 35 years in one, but no they are small SS funnels that I slipped over some slightly flaired aluminum tubing and Hysoled in place. Another idea I saw once was a guy who put one of the small plastic fuel filters on the end of the vent tube connected to more tubing to the bottom of the firewall. He had drilled a couple of holes on the top end of the filter to provide the pressure reference.
I had problems with fuel dripping from the vent lines and onto the exhaust a lot, during particular rough starts or particular rough landings
The smell doesn't bother me, but the fear of fire got a hold of me....
So I wen't and got myself two soup ladels for 5 bucks (euro's that is overhere)
Being involved in maintenance of regular certified aircraft it cracks me up to be able to use this kind of stuff on an airplane
