OK guys, strange question.
I currently have a Christen wobble pump, it was there since the machine was built in the 70's and has just had an IRAN and runs well, the aeroplane is currently being rebuilt.
I like the simplicity of the wobble pump, gascolator and fuel shut-off all in one but also am thinking about the ease of having the electric pump should the need arise. I'm not super worried about having to wobble the pump should the engine driven pump fail but there are quite a few places in NZ where the time between suitable landing sites could possibly exceed the arm fatigue factor.
The engine is running a Rotec TBI so only need low pressure.
My thing is that I am lazy, I would really like to just run the hoses and everything pretty much the way it was. I'm not to keen on doing a system redesign, find places to put the pump, associated filters, fit a gascolator and fit up a fuel shutoff.
Can anyone see a reason why you couldn't run a small electric fuel pump directly after the wobble pump, utilise the inbuilt mechanism of the Christen for fuel shutoff, gascolator and filtering?
Just a thought.
