Inlet snorkel and ramp

August 12, 2019 – Didn’t do all of this work in one day. Had a trip to a little town in Wisconsin somewhere in there…

The drama with the inlet ramp continues…

First I made sure the snorkel is located where it’s going to be. I ended up using a hole duplicator to drill the holes in the snorkel at the fuel servo. A #10 hole finder fits perfectly on the threads of the servo. Then I used the blanking plate that was on the servo to take the holes up to 1/4″.

Here’s the snorkel in place. I have read about a lot of interference with other items, especially the lugs on the starter. I have one lug that just touches. When everything else here is done I think I’ll just cut away a little bit of the snorkel and glass a flat piece right there. I don’t really want to grind part of the starter case.

Now I have my second inlet ramp. I trimmed the side like the first on, and left a lot of material on the front, just so it fits in the cowl.

Now the snorkel is just to the outboard edge of the ramp…

I have the vertical section of the baffle in line with the edge of the cowl lip per the instructions.

It makes sense to me that if I move that piece outboard into the middle of the cowl lip, it shouldn’t matter. As long as that gap is sealed later on…

So I ordered inlet ramp #3…

When it arrived I trimmed it less than I did ramp #2. Much better.

I moved on and marked and trimmed the hole for the air filter.

I started fitting the filter support brackets and drilled them to the snorkel and structure as needed. Here’s the aft one. It fits nicely under the baffle behind the snorkel.

I had to trim each piece even from the original dimensions given in the instructions. But I like where this is going.

The next step is to enlarge the hole in the ramp so the filter fits down inside the retainers and flush with the ramp.
