rossboyer Report post Posted November 26, 2020 Probably about midway on engine near top. It is about 9” long and 3-1/2” dia. Be sure ti usa a Cat filter that is 2 micron filter. May or may not have a pump on it. If it doesn’t have a pump, I have the parts list you can order to install. Not hard to do if you have a set of socket wrenches.
