Did not receive all items

Even though this was a Ford OEM part. I did not receive everything I needed to do the job properly. I was missing the gasket for the fuel pressure regulator and an O-ring for the fitting of the fuel line. I was very disappointed and had to get another kit from Napa.

Does what it says. Fuel pressure remains constant throughout engine cycle. 10/10 would recommend

Answer

The Ford service manual does not list a torque specification for the fuel pressure regulator cover bolts. You can lightly snug the bolts up. (Torque specifications are not needed in this installation.)

The "Blue Spring" Upgrade Kit can be a fairly simple installation as long as you’re familiar with the truck. (Between 25-45 minutes) – The item is installed on the side of your fuel filter housing under the hood.

Will this help MPG?

Answer

Most trucks will actually quite down at idle, rev much quicker and with the added fuel pressure it’s not unlikely to see an increase in fuel efficiency.
