I have an IO-320 with a Superior cold air sump installed in my (90% done) RV-4. I decided to move the cowl air intake forward rather than deal with the snorkel arrangement I had on my RV-8. I was planning to use the Flyboys Accessories intake arrangement with the cone and filter connected to the adapter ring on the front of the injection servo using a short length of scat tubing.
Before doing any installation I checked a few measurements. Ooops. Basically, the filter and cone will just fit if I connect the filter direct to the adapter ring on the servo. But that means I cannot fit any sort of alternate air arrangement between the filter and the servo.
So my question is - is an alternate air source essential? I've never had to make use of the source in a few of hundred hours behind injected engines of various flavors.
If the answer from the cognoscenti is that Alt AIr is essential - any good ideas about how I resolve the problem?
AS ever - many thanks in anticipation of advice.
