Thomas,

All fuel lines are 3/8". I initially planned = for 1/2"=20 through the Andair using the 20-25 duplex valve. Got talked out of it. = The RV10=20 kits for the 260hp Lyc are using 3/8 lines. The 20-25 value supports 1/2 = NPT /=20 AN8 connections for the suction side. 3/8 for the return. The 20-20 = valve is 3/8=20 both directions with AN6.

Each pump has=20 it's on filter not each tank. Some of the short sections of fuel line = between=20 the filters and pumps may change to fittings depending on room and area = required=20 for servicing the filters and pumps. I am also not ruling out some flex = hoses on=20 the low pressure side. Need to get my Andair. I ordered it three months = ago.=20 Every week they tell me it is ready to ship :( still not=20 joy!

Fuel Rail parts and injectors?????? Still = waiting to see if=20 Bruce and Tracy's are going to offer a Renesis intake.. :) =

Bobby,

IIUIR, you are pluming:

1) Each tank to the Andair

2) From the Andair to the pumps

3)...rest of the plan

If so, Why not use 1/2" lines Until the=20 pumps?

Do you use any kind of by-pass for the=20 filters?

2. = Use (expensive)=20 Y blocks to reduce bends and provide sensor ports. =

3. = Filter before=20 and after pumps.

4. = Auto fail over=20 circuit to switch on second pump at 28 psi.

5. = High pressure=20 bleeder.

6. = 3/8 lines.=20

7. = All cabin fuel=20 plumbing mounted to plate on floor.

8. = Firewall=20 bulkheads on cool side of engine.

The = pressure drop=20 and flow rate of the AC Delco Filters is unknown...AC Delco will not = provide=20 specifications. Will need to measure.

This = is the same=20 basic configuration the EGG's are running so it should provide a = larger group=20 of planes with this design in the air sooner.

Flame=20 away!!
