Vacuum Pump
From Bondline
I had a Sigma Tek Aeon Dry Piston Air Pump installed on my 1974 Traveler. The pump fit under the cowling with no problems and no modifications required. I have a spin-on oil filter and there was no problem with clearance from the filter.
In order to install this vacuum pump you will also need two fittings, aircraft spruce part numbers 10-01151 and 10-01152.
