Installed without taking off oil pan, little tricky but possible. After priming when starting the engine, pressure came right up. Seems to work well. I would recommend having a higher volume oil pump because of the 5.4L engine design. This should solve many underlying problems and look forward to this engine lasting for a couple hundred thousand more miles. Thanks, mark

Installed in my 2008 f150 5.4 and is working great do far no issues. I also installed one in my 2005 expedition a few years ago and worked great for 2 years untill i sold it. Would highly recommend this oil pump. No one else had this pump, its sold out everywhere else.

This pump is a must install for the 5.4L 3valve Ford Triton motor. It straightens out a lot of the running issues having to do with variable valve timing. If you are ever in the front cover of the motor, do yourself a favor and just replace this.
