Default Water Pump Issue and question

I have a 94' with the LT-1 and installed a new water pump a few months back and now it has coolant coming out of the weep hole. I know this means that it will need to be replaced again. My question is this, I want to go to a electric pump on the water pump, has anyone done this and does the kit come with the parts that will fix my current pumps issue or do I need a whole new pump?

The EWP kit replaces the internals of the stock pump and also blocks off the weep hole with a freeze plug, so no - you don't need a new pump (assuming your housing isn't trashed - a very unlikely scenario).

LT1 is our old chevy motor, LT-1 is a really old chevy motor.

Did you buy a GM pump or an aftermarket replacement? Some of them have some poor build quality. As for your question of EWP the pump comes with a plug for the drive. You have to clearance the front lip for some of the electric pumps. You also need to press the impeller shaft out of the pump to install the plug in the back of it. The only aftermarket electric pump that I know for sure doesn't require trimming of the fan shroud is the CSR pump.

The pump I currently have is an after market on picked up from AutoZone. The EWP I was looking at is this one . The housing appears to be in great shape, but I haven't pulled it off yet.

I will look into the CSR pump also.

Meziere makes a great pump as well...the reliability and the name made me spend a little extra, (240) for the 55hd pump.
