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.

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.
