Loose wire connections on AquaHot....

Hmm, Wonder if having really "goose loose" wire connections at a ground stud would cause the fuel shutoff to leak diesel?
I have a bunch of what looks like bakelite in the bottom of the burner tube as well..... ideas anyone?

Loose ground connections are not good for operation as it can certainly affect the voltage of the signals to the control unit to tell it things are working correctly.  Low voltage signals usually means a problem.  But that does not lead to a fuel leak.

Trying to fire the burner with no spark from the coil would result in 5 seconds of fuel being sprayed into the combustion chamber and then faulting.  Doing so repeatedly would look like a fuel leak out of the exhaust.

Most fuel leaks that occur with the burner firing are from the shaft seal of the fuel pump.  The leaked fuel drops out the bottom of the burner case onto the fuel lines and into the pan under the burner, ie. not out the exhaust.

Hope this helps.

The igniters are made of black Bakelite material. I just ordered 2 for mine. They were "eaten" up at the tip losing about 1/2 inch

Thanks Rudy, will just figure out how to get a couple more wires disconnected and ship it off to Roger.
