On our 360: Howard and I have had a continual problem with the header tank
geting small leaks around the seal.  The last time I put two BID around the
edges and that seemed towork but now we have a very small leak again.  This
appears to be caused by inadvertantly pressurizing the header by pumping in
too much gas.  Our overflow pipe is the same size as the inlet pipes but
there are two inlets and only one exit = POP.  It seems easy to just not
pump too full but the sight gauge gives different readings when you are
going up or down...  Someone showed me a detector for the overlow line - it
lights up a light on panel (or turns off the pumps) when it detects gas in
the line.  Anyone have info on where to buy it?  Other ideas?  We are now
trying to only pump with one tank at a time so we can't overshoot but we
are still likely to screw up sometime.  We have looked into replumbing the
whole set up but it is too difficult on a finished plane.  
	Easy Solutions:  3M makes some new white hangars for walls or
refrigerators that can be easily taken off by pulling on a tab on the
adhesive, the adhesive pack stretchs, put in a new adhesive pack to put it
back on.  I used 1 1/2 inch hooks and put one on each side just behind our
heads tohang the headsets = works fine so far.  Very cheap and doesn't
screw anything up.  Take it off without hurting the finish if you don't
like it.  They also make a note holder for little reminders (frequencies
etc.)  Get them at Loew's or Home Depot.  I also noticed an AD in AOPA mag
last month for something I was about to invent = a timer that vibrates.
Set it for ten min, put it between your legs and you will remember to shut
off the pumps or change tanks etc!
