Just browsing through the WWW and found the following on a site about
oil fired burners

"If you have problems with fuel leaking into the combustion chamber
during the off cycle and rumbling when it starts you can add a solenoid
to stop this problem. When the pump pressure drops below 80 PSI. a valve
should stop the flow of oil, if it doesn't oil will continue to flow if
the tank is above the burner."

I think that my bruner does this when it turns on. Also my tank is
located above the burner. Has anybody ever come across this scenario?
Me thinks that if the oil does leak into the combustion chamber it's an
awful waste of oil???


I think that this means you need a new pump. Sounds like
that is causing the leak. If the pump isn't turning no oil should get
through. Does it burn odourlessly and smoothly? I'm not sure what the quote
means by
'rumbling'- perhaps rough burning? If so it is more
likely that the baffle needs cleaning or adjusting.
