Very easy product to install. Instructions were detailed and had notes, in red face type, that sealant was required for the NPT port. Only issue I had was from the fuel warming element in the fuel filter head. There is an O ring there that should be replaced when removing the spring and ball, actually two O rings (one in the center and the other on the positive connection to the warmer. Directions did not mention those and I really should have used common sense. My recommendation is to buy the fuel head seal kit, comes with 5 O rings, 3 screws, and the bleeder screw when you do the delete. This way you can replace all the seals at once and they are really easy to swap. I only replaced the two on the bottom side of the fuel filter head and no leaks. As for the machining, I felt like the product was great. WIF spun in nice and smooth and it attached to the fuel head nicely.
Not a quality part.

Needs to cone with the necessary replacement WIF sensor O ring as the old one should always be replaced anytime it's removed per the dealer (that's why my install kept leaking), and I had to buy a new WIF sensor to get the O ring. Directions should also state that pipe/thread tape is needed on the NPT port to stop leaking (which is another spot min kept leaking). The biggest let down was the burred threads on the WIF sensor which made me reuse the old WIF sensor but use the new O ring. A little quality control goes a long way. Not a smooth install due to those issues but it works now without leaking.

How does this install?

Do you have to modify anything to put this in Are there any parts to be removed when installing
View Staff Answer 
You will need to either reuse your factory WIF sensor or you can install a WIF Sensor Plug found HERE. Other than that, it's as simple as changing your fuel filter.
Will the factory prime button still be functional after installing this?
