Hi sorry for the question I have a Kia uses same fuel pump assembly I recently changed filter but I'm losing fuel pressure I lost one of the o rings that goes on opposite side of the fuel pressure regulator. My question is if I used a smaller o ring thinner diameter instead can that cause/ be my issue with low fuel pressure??
