Brian, You got any pics? See N64KR at http://KR-Builder.org - Then click on the pics Daniel R. Heath - Columbia, SC da...@kr-builder.org See you in Mt.

Mine has one pump (facet) with a left and right switch that pumps out of the wings, to the header tank. It just dumps it into the header. I do not have a low preasure or low level light but you can feel when the pump is pumping air. On mine the pump is under the pax seat. Now I do not know where the origional owner got the valve to switch tanks but...You could put switches and light all day but all you do is create a larger problem Now to refreash, one pump is all you need. These things (pumps) are fairly reliable and you should be able to see if all is working well. Brian G. Douglas Killeen Texas N8575C KR2 (TD) NOW at the airport after a restoration.
