Beckett Cleancut Fuel Pump

Usually the burners are set between 120-140 depends on the brand-manufacture and how the air bands are adjusted. I have had to raise and lower the pressure a little in that range to get them to burn clean sometimes. I would have to look again but I think there is a gauge port on the side of the pump.
 
I believe you have to make an adapter for the copper tubing and test the pressure at the outlet. I personally hate that fuel pump. I've seen the solenoid valve go bad, and fuel keeps dumping, at a much reduced flow, into the combustion chamber. There's no gauge port, and no cutout pressure adjustment. I rarely replace a clean cut, but instead replace it with an A2VA-7116 fuel pump and the solenoid that is required for the machine voltage and a brass outlet fitting.

And...140 or so is where you want to be with #2 oil or diesel. Kerosene doesn't require that much pressure (100 - 120) to properly atomize for a clean burn. Diesel needs the extra pressure to mist out right. Diesel does, however, offer better lubrication to the fuel pump.

you know, ages ago, (and I was there, yes..) burners had to be set for the fuel type. They used different air cones and fuel pressures to properly combust diesel (#2 oil) or kerosene (#1 oil).

Thanks Paul, went to mount the gauge today and noticed that it is not a Suntec fuel pump... reduced burner nozzle size on Largo hot box from 3.00gph to 2.50 gph and adjusted the air bands for clean burn - wanted to check pressure since I changed these other things and noticed there is no gauge port.

Russ, the fuel keeps dumping after trigger gun is released?

I was trying to read up on fuel pressures and came across what you are saying about different air cones and such related to different fuel types...

Us young(er) guys have got it a whole lot easier than our predecessors!
