Hello.. Im wondering which way the suction seal in the main part of the pump faces. I cant quite make it out on the pdf pic Im looking at. It makes sense to me that the cupped side..side with the tension spring should face the bearing in both the pump body, and the cap. These are the seals that seal the thrust bearing if Im using the wrong terminology. You are right both to the inside.(rivertard).

Thank..!!
