The header tank is 61/4 in wide, 81/2 inch deep(front to back) and 41/4 in
high. This holds about a gallon. The front fittings are bulkhead AN fittings
that I welded to the tank and simply drilled holes in the firewall and used
bulkhead nuts to secure the tank. I put some small ears on the bottom and
riveted it to the belly as well. It could be made wider and longer front to
back. I just folded up some aluminum on hand and welded it up and leak
checked it.

George,
How big is your header tank (rough dimensions)? Where you describe you
placed it (if I understood) there isn't lots of room with rudder peddles and
all. In the reading that I have done they suggested a minimum of 2 gallons.

Phil,
They are correct that a return line is not required. That said, on my
Io540-G1D5 instillation I am using a header tank and putting a 1/4 return
line from the throttle body inlet to the header tank. It will have a
restrictor on the line about 1/16 inch drill size. The header tank is then
vented back to the right main tank. The header tank is fed be the tow main
tanks and I located it under the floor on the right side right up t the
fire
wall. It also has a drain out the bottom of the airplane for the low point
in the system. The reason I did it is that it allows me to circulate cold
fuel on hot days during starts as well as a last chance for any air or
vapors to "escape" back to the tank. It is extra work, but I think it is
worth it. I basically copied a fuel system from a certified aircraft with
the same engine.

I am doing the fuel system in my SR3500 and would like to know if any
anyone knows the volume of the return flow from the fuel injector
(lycoming
part #77003). The engine is an IO-540 G1D5 with a bendix fuel injection
system. The reason I am looking for this info is to decide if I need to
run
a return line back to the tank, or if the flow is minimal, I can tee the
return upstream of the gasolator (with a check valve). Thanks in advance
for your time.
