Woody, leave it to me to be confused after you explained everything

What do you mean connect the cores in parrallel? You mean one after the other? Or something else... I was just planning to have flow go in one core, go out, and go into the next core, then come out and go to the I/C. Did you have something else in mind?

After thinking about it, I thought hmmm maybe I should have a hose splitter (which may not even exist) split the hose from the pump and have two hoses, one for each core, and then have them merge on the way out before the I/C. It would definately make up for the 3/8" tubing.

But.... thats all just a thought. Please explain what you meant by connect parrallel. Unless my idea actually covered what you meant...

Wow I'm all over the place.
