This post is long over due and I will try and take photos to add at some point. Bottom line, the FVP water pump did not fit properly with the other OEM LT5 components.

At some point I purchased the water pump from RockAuto (FVP # 1307180) to replace my OEM pump which had its bearing going out. I think the FVP was the only available pump on the open market at the moment of purchase.

We installed the pump at Jim Voter's house. The pump itself installed fine and functions fine. But when we went to install the air horn, the alternator (which has a bracket that bolts to the water pump) was now seated too high preventing the air horn from being installed.

The best we can figure is the (3) holes on the FVP water pump (where the alternator bracket bolts to) are out of spec, raising the alternator bracket, which in turn raised the alternator, preventing the air horn from being re-installed. We were unable to make any adjustments to the other alternator brackets/bolts which would make an difference.

So, I recommend staying away from the FVP water pump.
