I guess I have two sizes up then, as it is 100 mm.
Yesterday I was test fitting it and noticed what you are saying, so I think I will just weld the adapter to the correct angle.
The existing 75 mm hose goes through a hole in the bulkhead and then bends down at about a 45 degree angle. My thought is if I weld the correct angle it will save me the headache of bending either hose.
I will compare it to the original one more time, as I am a little concerned that if it is too much taller than the 75mm, it could be a problem. I am concerned that the height of the intake side will be too high and allow backwash into the motor
