Dear subscribers,

I am working on rebuilding an older 4P kit (serial = #207).

The pressure pump for the door seal is located in the fuselage. The pressure line runs along the door and runs through a steel = tubing that moves in and out of a grommet when the door moves. I suspect that = this is a possible source of pressure loss in the = cabin.

I saw on pictures of newer models that there are = contacts in top of the door that obviously feed power to the pump (looks like the = pump is now in the door).

I am wondering if I should move my pump and the = pressure switch for the door seal in the door. What would be the best way to get = the electric power in the door – should I run a cable from the door to = the fuselage or should I go with this switch that makes contact when the = door closes. I would need 4 wires (2 for the pump and 2 for the = switch).

Thanks for your advise.
