Came out this morning to a small p/s leak. Turns out the large fitting Canton installed was leaking. Had to remove the fitting, reapply teflon tape (being sure to remove all traces of original teflon tape so as not to introduce them into the pump or rack & pinion) and reinstall. I suggest those of you that have already installed your reservoirs to check yours for leaking where the large fitting screws into the aluminum 1/2" NPT bung on the side of the tank. If you haven't installed your tank yet, might want to check the fitting for being loose.
