Bob,

Finally got around = to figuring=20 out why no EGT. Tried grounding one line. = Nothing. Took=20 apart the connecting where the EGT ends and connects to your = wires. EGT=20 wires (from ACS) are red and black. Yours are yellow and = red. I=20 had hooked the red to red and black to yellow. Seemed to make = sense. Wrong. It's the other way around.

Monty, = Yes, pumps in=20 the tank is the way to go. I considered it, but with all that = I had=20 to do, and they were working on the firewall for so many others, I = went=20 that way. I had a chance to play with things today. At=20 low RPMs I ran it and played with it, using the AutoOpen page = to get=20 my info. and tuned from there. At least up to 16 = inches. =20 No stumbling and no pump problems. I shut down when oil = and H20=20 got to 210. Let sit for a few minuets and tried the=20 pumps. Both cavitated. Opened the oil door to = let=20 heat out for 10 mins, and the lower pump started pumping a little = and then=20 the upper pump started working. Heated it up again. Shut down and the same = situation.
