Hey David,
You may want to check the fit before final installation. I bought the TRF last year and the pump was machined out of phase. The mounting holes are designed to be slightly different, i.e. not exactly 120 degrees apart. When lined up using the provided holes, my pump was turned about 1/3 of a turn off where it should be. I had to widen the holes by about 1/8" with a drill press, and then it would fit in any orientation...including the correct one. Not saying this is still a problem, but better to take care of it prior to mounting the pulley and gooping the gasket if it is!?!
