This fuel pump test directly to a battery was a success. It is the first time I've actually heard the pump run.

I guess I have a power issue, rather than a pump issue.

Now to figure out why I am not getting power to my pump. My connections are in the photo below.

I only have one starter battery connected. Do I need to have both batteries connected?

Take a voltage reading at coil + when the key is in the crank and then in the on position.
The ground looks poor in the picture. Take a ohm reading from the bare wire from the fuel pump to the battery ground to see if the ground is working. I would fix the ground wire end terminal regardless - it's pretty far gone

I was able to get the engine running.

But I have discovered a new problem. I have water coming out of the top of the engine. I'm assuming I have bad seals? Any experience or Insight would be appreciated as I plan my next steps.

Could be bad seal (could also be no seal...), torque insufficient, or wrong installation...

Is the water coming out from under the t'stat housing or out from the studs?
If it's the bottom probably just the gasket leaking, try a new one and seal with Permatex Av grade. If you are using lock washers get rid of them and or add some sealer to the washers and nuts for a good seal.

I removed the seal and thermostat. I will get a new gasket and replace it with sealer and report back.

If you soak the thermostat in vinegar for awhile the soaking will clean it up.

The vinegar worked very well. Thanks for the tip on that.
