Lycoming operation without engine fuel pump

[Clouddancer]

I wondered if anybody ever operated a Lycoming engine without using the engine's mechanical fuel pump, only using electrical fuel pumps? I know this sounds odd to most of us...

The idea comes from my own requirement to use Mogas. Therefore I'm looking to get rid of all points in the system that might cause the fuel to evaporate. The mechanical fuel pump is the highest point in the fuel system and gets a good part of the heat, especially if the engine is shut down. If the mechanical fuel pump could be omitted, also the fuel lines could be run much more directly.

As I said, this is only an idea. But I'm interested to hear your opinions or even your experiences.

A member of this forum does just that. He has two electric pumps, one in each wing root. Try "search" for elec. fuel pump/ wingroot/ etc. and you'll most likely get all the info you need.

There are others where he posts some pictures I believe but you will need to search - I didnt find them right off the bat and gave up.
