you should be ok as long as the boiler has been serviced recently. its the injector that controls oil flow. if its not been serviced recently get your
local oftec registered engineer to service it and tell him about the pump first.

I'm not sure about the grundfos pumps but the suntec pump on my boiler is positive displacement and relies on adjusting the bypass valve to
control the flow. There should be instructions with the new pump but if not you can usually find them online.

I've borrowed the kit and set mine up as per the instructions in the past, but I've a friend who is a heating engineer specialising in oil
and he told me he has never set a new pump up, just runs them as they come out the box with the factory settings.

If you are changing to a different make of pump the pressure may be slightly different. The mixture strength is varied by throttling the inlet to the
centrifugal fan with a sliding plate arrangement. I believe there are instruments to measure the exhaust gas oxygen content but when I got mine set up
the service engineer just increased the airflow untill it stopped smoking!!
My boiler was 10 years old and I ended up replacing most of the burner components within the next 6 months - wish I had bought a complete burner it
would have been cheaper!

My boiler is over 30 years old now and over the last 15 years I have replaced the fan motor, the oil pump, the solenoid, the coil and the HT leads.
The only major component I haven't changed yet is the control box and that's held together with tank tape.
I keep thinking about a new burner unit but I just don't want to invest that much in such an old boiler so I just replace what's needed.
The biggest difficulty is identifying the faulty component.
