I followed this to the letter.

Should be no reason you can't use your old one as a donor.

Good luck. Love mine.

Definitely use your old one as the donor! I have had the Meziere electric pump in the stock pump housing for almost 10 years now. I did have to have the electric one rebuilt about 4 years ago.

I think when I bought the electric pump, it came with the right size plug. Did yours not come with one? It's been too long for me...

The Meziere pump comes with a plug for the water pump housing, not the timing cover.

Default water pump gear

Is it absolutely essential to pull the timing cover and remove the water pump gear?

You can leave the water pump drive in place, some do. But, eventually you will more than likely develope an oil leak.
