which way are you talking about? i have mine tee'd off betwen the CP3 pump and the fass pump. but i do believe that port on the fass pump is between the two filters or it may be after the two filters.

 

Sorry for the confusion. I should have quoted dodgezilla. I meant the pressure reading on the replacement filter cap from Geno's. I wasn't sure if it was reading pressure before or after the stock filter to the CP3. To me, it would make more sense to read the pressure feeding the CP3 so you could tell if your filter was restricting fuel flow or not. I'm hoping the cap does this as it makes installs much easier especially for an electric gauge.
