Greetings,

"Yee of little faith" here decided to believe Ed, and not install bleed fittings in the top of my evap cores. Today's log follows. I imagine the mechanical pump would have done the job in several iterations of running, but I don't want to have to go through that every time I drain and fill the system. Fortunately, I left the cores clecoed to the mounting brackets for just such a reason. I'll be welding 1/8" pieces to the top of one tank on each core, and threading it for 1/8 NPT. If I can find a nice petcock locally, I'll use that, otherwise, just a plug for now.

Did a lot of fiddly things to get ready to fill and start the engine. Unfortunately, when trying to fill the water, I couldn’t. The EWP wouldn’t pump, because it wasn’t primed. It can’t get primed, because there’s no water in the evap cores. There’s no water in the evap cores, because I listened to Ed and didn’t install fittings in the top to bleed out the air :-) Installation of the bleed fittings is under way. There was also a pinhole leak in one of the EWP flanges. I need to fire my welder. It has now been “JB welded” within an inch of it’s life. If it leaks now, I’ll just have to throw it away.

Cheers,

Rusty (Ed, you owe me a beer <g>)
