So I installed my 2 mic between the cp3 and stock filter this past Friday. I noticed a few things.
1. The Donaldson filter touches the return line from the cp3 to the stock canister.
2. The adapter that connects filter head to the 90 pushlock touches some of the wiring harness next to the engine ground.
3. I am getting a little seepage between the Donaldson filter and the fleetguard head.

Are these common issues? I am thinking of getting the adapter from GDP that connect filter head to pushlock 90 as the pics show it mounting flush and mine lacks about 3/16".

Am i supposed to remove the gasket that came with the filter head to use the Donaldson. I remeber reading saying something to that effect for the CAT 2 micron?
