Paul, that is where my sump tank is located, on the firewall below the spar
opposite side from the engine. Originally it was on the engine side, so I
made it out of steel. Holds about 1 gallon and has two Mazda fuel pumps inside,
fuel return is to this sump tank like Ed's. The selected main flows to this
sump tank by gravity so it is mounted low.
Maybe you can find a local welder in your area that can weld aluminum. I
found a guy near me that does. I take water pump parts, intake manifold parts,
etc. to him for welding. I just tell him they are for my RX-7. Design it
yourself, get the sheet aluminum, cut out the pieces, and take it to the
welder. I think 6061 is good for welding but 2024 is not.

Hi, Ed.....thanks very much for the information
regarding the fuel tank header. That's exactly what I need. Unfortunately,
I'm not a welder. Since I'm building a canard pusher, I plan on installing
the fuel sump/header tank on the firewall on the side opposite of the engine.
That is where my strake tank fuel lines lead to, and it should be considerably
cooler just under the main wing spar. If there are any welders out there
that might want to tackle this project, I'd like to talk to you. I'd feel
much better paying someone to do this right than attempt it myself. Thank
you. Paul Conner sqpilot@earthlink.net

[FlyRotary] Re: Fuel Header Tank
Hi Paul,
My rectangular header tank was
home made out of a piece of 3 1/2 x 1 1/2 x 8" rectangular aluminum tubing
caped with aluminum plate. Welded in AN fittings for fuel inlets and
outlets. Has worked well for me, eliminating the need for a return line
to the wing tanks. However, being under the cowl is not the best location
for it. Picks up heat and with auto gas has shown signs of fuel perculation
on hot days. I have a cool air blast tube cooling it as well as a low
pressure boost pump that provides enough pressure to keep it from purculating
on a hot day. Better location might have been the wing root location.

[FlyRotary] Fuel Header Tank
I was surfing the net regarding 13B
engine installations, and I found some pictures of Ed Anderson's installation
which showed a rectangular aluminum header tank next to the fuel pumps.
Anyone know if this is commercially available, or home grown? Ed
??? Thanks in advance for your replies. Paul Conner, 13B powered
SQ2000. Engine installed, trying to hook everything up.
