Has anyone successfully connected the snorkel provided in the kit with the FM-150?

Just did it. Had to cut a section out of middle of snorkle, fit both ends, fill middle with foam, sand to shape, glass, cut out foam. Fits like it was made for it now.

That is what I was expecting to hear. With the installation of the spacer required with the FM-150, it appears the filter end of the snorkel is too far forward - about the thickness of the spacer. Ugh.

Default Snorkel Fit

I had no real trouble with the snorkel fit. However I found the snorkel ended up being too close to the exhaust pipe and I had to cut that section out and relay the glass cloth making it bulge a little inside the snorkel thus giving it a greater clearance.

The air filter upper lip did not make a perfect fit with the lower cowl and I was forced to make a modification by building the lower cowl up and fabricating a new cowl rubber. I don't know how to put pictures on VAF so give me a day or two and I'll photograph my alteration of the cowl and get my good mate to post it on this thread very soon - hope it helps others.

Default Removable front ramp rubbers

On Alan's RV-14A,the air-filter would sit level with the cowl lip and no amount of massaging the cowl or ramp would fix this.

The easiest solution was to make the front ramp mounts removable.
The baffle rubber is trimmed to fit the exact profile required then a piece of 1/2" x .063 is used as a retainer. The seal is attached to the .063 retainer with Sika and held in place with #6 screws. The nutplates are fitted to the lower cowl. The area in front is filled with micro and sanded to the intake profile.

It makes the lower cowl removal easier, also the rubbers are not stretched and damaged every time the cowl is removed and replaced.

I have used this method on several RV-10's with three bladed props and A/C and have found a lot less effort and less paint damage with lower cowl removal.
