Fluctuating oil pressure on Rayburn burner Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

[mortod]

When I attach a pressure guage to a Rayburn 480K (a Nu-way burner) the needle vibrates so rapidly that I can't even take a reading (the guage is working fine on other burners). What is the likely cause - I assume the oil pump, or is it possible to just replace the pressure regulator part of the pump? The burners are working fine otherwise. Generic answers fine if not familiar with Rayburn.
