Great Product with an Easy install

I recently purchased this filter head to replace my stock one that was constantly losing prime. This was one of the easiest upgrades that i have ever made. Put the spacer in to move it away from the engine which made installing the fuel filter much easier. Deleted the WIF sensor with the billet plug available. Pretty nice to have that 3/8 square to install the plug rather than taking channel locks to get the nylon one off. Very well-built product and oh they shipped this very quickly!! Thanks Dmax Store!
