Hi, Jim....my fuel selector valve is located in the top of the center console, right about at my elbow when seated. I did not want to run it all the way up front like the LongEZ. The fuel selector valve is downhill from the main tanks, and then the sump is downhill from the fuel selector valve... (Also convenient to the reach of any back seat drivers). This way I was able to keep the fuel lines short and keep everything continually running downhill from the main tanks all the way to the EFI pumps. Paul Conner

Where is your selector valve? If it is on the floor up front like an EZ you might be able to suck some air through the selector or cavitate on the long run from strake to near IP to sump. What if you went with the system Tracy uses? No selector - transfer fuel from transfer tank to draw tank as needed and draw / return to draw tank. Gravity feed from draw tank to sump, boosted with Facet. You have most of the plumbing in place and it wouldn't be a big deal to convert.
Do you really REALLY need a selector? ... Jim S.

I'm a little confused...I have both. I have a facet low pressure boost pump between the fuel selector and sump tank, and two high pressure EFI pumps after the sump tank, before the engine. Paul Conner

Other folks have reported fuel flow problems when they located
their pumps
between the engine and fuel selector instead of between the fuel
selector and
tanks... mostly the cause was air being sucked past the fuel
selector's seals
causing some air to be introduced into the fuel flow.
Good Point Marv,
