All,
If you've used the FFR corrugated tubing and filters, I could use your help and advice. I checked out a few threads already, like sgarret's build and the silicone coupler discussion, but I haven't found what I needed.

My donor is a 2006 WRX. Earlier today I tried following the manual and put the thin, smaller coupler "sleeve" on the water pump. I could not for the life of me get the larger coupler to slide over it - with or without the corrugated tube attached. I tried a spare large coupler without the little sleeve on the water pump and it felt right around the pump bead/collar, but loose past it. What have others done?

Also, my hard lines had crazy cracks in the rolled bead. Anyone else experience this? I wonder if it happens to all of them eventually, only we never see after it's installed. I'm going to reach out to FFR and see what they can do about it.
