where
Where are you planning on installing it. I have seen LOTS of installs on the firewall same place as vans basic gascolator.
Personally, i am trying to do the planning to mount one on each side of fuselage outboard. then a short flex line to the tank. I have seen this done on a 7a and it was great. The space inside the wing root on the 9 is smaller then the seven. Not an easy task, but my thoughts are that it is better then putting past boost pump, less connections/chance of vapour lock etc inside the firewall, and at the wing roots will allow me to take samples, etc and keep the afp filter inside clean for many years. Just my thoughts, good luck
