I used a Perry pump in a plane that had the fuel
tank a bit low creating some fuel feed problems.
The engine was an ASP 65 and I activated the pump
off of the exhaust. It seemed to have enough pulse
from the exhaust to do the job and solved the fuel
feed issue. I have not tried doing the same thing
with a 2st but it may work also depending on
the application.
I also have a Cline system that I have not used
yet but expect that it will work fine.
