My name is Jon and am new to this site. I have an 03 6.0l and very happy with it so far......minus the minor flash issues. Anyways has anyone installed an engine oil pressure gauge? If so where did you tee into or is it a major pain. The only place I could see that might be easy was where the EOT sensor sits. I know there is a test port under the EGR valve on the EGR cooler but that doesn't look like much fun either..
