I thought I would update my filter situation and cover a few things that you all mentioned. It's pretty clear now. What happened was that the pulsating back and forth while trying to crack open wet wood with a partially plugged or ready to be changed filter, Ruined the filter 1st then the bypass valve and the bypass components plugged the return line causing the filter to either blow the gasket or split open. The filter head was a Cross brand and the return mechanism is considerably lighter duty than the new head I bought from Northern Tool. Also I didn't know that I should have a gauge on the head to tell when the filter was getting to the end of it's life. New components installed and all seems well. One last question. Is there a problem installing the filter upside down or horizontal? Thanks for all the help.
