Got things plumbed and moved again yesterday. Too beat to post it. Pump is now behind the front bumper down low. Call it lower and to the driver'* side from the driver'* foglight. That freed up more space for a future slush-box if I go that route for the summer. Should need it for afternoon test/tune, but not for morning competition.
Added a little green food coloring to make it easier to see flow/bubbles. Thought red would make brown with the little bit of green coolant. Still burping out a few air pockets, but it seems to be flowing better now.
Car is running MUCH better, but more testing will be needed. I need to lean out my AFR a bit. A short run last night was running 13:1 at idle.
