I took my lpsv out I remove the rear return line at the same time beings it comes out of the lpsv. After I did that the rears locked up bad, so I used my trusty hammer and flattened out the rear line a bit. I would tap, try, tap etc till I got the bias correct. I have been meaning to change it along with some other stuff just havent gotten aroud to it yet. Ive been to busy with other projects.
