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!

Will this allow fuel to get into the foam of the spar??
Or is there foam in the spar?? Virg

Oh wow! Bad news! Never thought about that. Fuel disolves blue foam.
Be careful with that moldless construction.
