I am wondering if anyone has installed a backup/larger fuel pump for a Continental IO-240 engine installation. The Facet fuel pump that came with my KF 5 Outback is only for priming the engine. It doesn't provide enough pressure/flow to run the engine in the event of an engine driven pump failure.

On certified planes with fuel injected engines there is usually an aux pump capable of keeping the engine running in the (unlikely) event that the engine driven fuel pump fails. Without one you become a glider . . . with an engine that could run otherwise.

Specs for the IO-240 show that it requires 35-53 psi of unmetered fuel pressure and about 12 gph at full power. I would think 20-25 psi and 8-9 gph would be enough to keep the engine running and get you home safely. I cannot find any 12 volt Facet or auto pumps with those kind of specs. I am getting ready to install the fuel system and think this would be the best time to make a change.

Is this something I should be concerned about or should I just stick with the Facet pump?

If someone has installed a larger pump what fuel pump did you use (brand, model number, specs)? Do you have pictures of your installation?
