There seemed to be some seepage around these hose connections
as well. Perry will be changing these to AN lines.

BTW when things aren't leaking Perry's cooling system works well
with a radiator core only 14 by 17 by two inches thick
mounted under the engine fed by the stock Long EZ NACA duct.
Even on the ground on a hot day. The reason this is so is the
air outlets from cowl are very close the fan disk so the fan
sucks the air through the rads. Works good with the stock
oil radiator too. The oil rad is  also mounted horizontally 
along the other side of the engine. It is fed air with an
armpit scoop shown down near Perry's left hand.

Perry is of course down on power a bit as his fan only allows about
5100 RPM max. This radiator size might need to be increased for
a higher HP 6300 RPM max engine.

The red box sticking down into the NACA duct opening on the right 
is Perry's steel fuel sump tank. The rads still cool despite this 
intake air obstruction.
