Thanks for all the input guys. I appreciate it. The main reason for the -8 line between the filter and pump was just for packaging purposes. -8 seems to bend a lot easier and the fittings are smaller, so I could pump the pump and filter closer together. Plus, since the threads on both the pump and filter are pretty small (3/8 npt), I didn't realize the -8 would causes much of a restriction. I'll go with -10 though as you folks suggested and separate the filter and pump a little more to make it doable.

Thanks again.
