My RV-6 is on about 1830 hours. I'll have an annual condition inspection in October, then I think there'll be engine work in 2021.
Current engine is a carburetted O-320-D2A with a Sensenich fixed-pitch cruise prop.
I didn't build the aircraft.
The current fuel system has plumbing feeding an Andair valve supplying the suction side of a Facet fuel pump on the inside wall of the fuselage between the pilot seat and the rudder pedals, with the pump discharge feeding a gascolator on the engine side of the firewall, which in turn runs to the engine-driven fuel pump.
It's still more than a year and a half away, but planning is good, and the direction I'm tending towards now is to take the O-320-D2A off and replace it with some variant of an IO-360, probably also with a fixed-pitch prop.
The change from carburettor to fuel injection is going to involve fuel system modifications: I'm anticipating that the Facet pump will end up in the trash, with a new high pressure fuel pump and new plumbing.
I'm sure someone has gone down the path of carb to fuel injection before, and if anyone has advice I'd love to hear about it.
Are folks generally keeping high-pressure fuel out of the cockpit, so where's the right spot for the electric pump? Is the gascolator necessary? Considerations for routing fuel lines to avoid vapor lock? How are fuel systems handled in modern certified aircraft? Anything else I'm not thinking of?
Thanks,
