Alright everyone, I finally got the motor together, and put it back in my 91 Accord. The motor is an F22A6. The problem I am having is that I can't get the crossover pipe (that goes between the water pump and the water outlet) to seal. The motor runs fine, but this damn tube is leaking water. It has new o-rings on both sides, and they are not damaged.
Both tabs that are on the pipe are bottomed out against the respective mounting areas.

Is there a trick to making these seal?

Thanks in advance
