Builders,
Before I dive in and drill holes, I wonder if I could get some opinions on
my plan for an EFI fuel system on my Cozy. It's modeled after that used by
Tracy Crook in his RV. I have installed the plans fuel valve and have the
gascolator ready. The much discussed EFI return problem now rears it's ugly
head. After sorting through all the opinions I'm ready to go with a transfer
pump system as shown at http://kgarden.com/cozy/fuel.jpg

The idea is to run a transfer pipe from the right to the left tank. The pipe
would come out of the rear of the right tank about 12 inches outboard of the
fuselage side and just above the inside base of the spar, through the spar
to the firewall. It would then go via a Facet low pressure pump on the
firewall to a similar line entering the top of the left tank. The EFI return
line would go to the top of the left tank through the spar.

Since my strakes are now sealed, I'm hoping I'll be able to get at the three
new fuel lines from the filler cap to apply flox and get a good seal. I'll
also be able to reach into the spar hollow to seal the lines as they enter.
All input, including neat ideas for sealing the pipes as they enter the
tank, would be appreciated.

I understand that the main disadvantage of this system is pilot workload.

Builder's who haven't sealed their strakes - solve this issue before you do!
