" Subject: RV8-List: FAB --> RV8-List message posted by: "Bob C. " I'm in the initial stages of fitting my Van's "Filtered Air Box" to my "O-360" engine with a Precision MA4-5 carburetor. Like for most of these carburetors, I had to cut a hole to allow the bowl drain to protrude into the "mount plate" (VA-131-C). My question is this: The above hole will allow "dirty air" to enter the "clean air part of the air box" unless you do something to seal it! What have others done to seal these cracks . . . or am I missing something?? Thanks, Bob Christensen RV-8 N678RC - In SE Iowa . . .

I have various medical syringes around the shop (we have a nurse in the family) which make excellent dispensers for the tube since the caulk tube is somewhat bulky. Use the syringes without the needle and use the original caps as a seal. The silicon can be put into a small size and a larger size syringe and you will get an 1/8" & about a 1/4" bead respectively with very good quantity control. I caulked all around the engine baffles, the carburetor mount plate, as chaff pads on my SCAT tubing, and other uses as I did my FWF and still had about 25% of my original supply left over after about a year of use and it all remained fresh with no hardening as long as I capped the tube/syringes.
