No I really wouldn’t.  My fear would be the float not sealing off and waking up to a garage floor covered with oil.  I had a bad oil leak once already.  Never want that to happen again!  I still havent moved to my metering pump.  I tried it for a while, but I must need to put a solenoid on the line up to the burner because there was residual pressure after the pump shut off and the nozzle would drip oil and make a mess.  Do you have some sort of solenoid between your metering pump and burner?

i do have a solenoid shut off valve with in 3" of the heater block. I do get a residual drip also. i have the burner tipped up at the nozzle end so the unburnt oil runs back down the blast tube  then it drips out the oil supply hole into a catch pan. not the best system but better than the mess it makes in the burn chamber.
You can't put it on the internet if it isn't true!

Do you guys think that the oil is seeping past the solenoid or maybe residual oil in the pipe from the solenoid to the nozzle?

I am thinking residual oil from between the solenoid and the nozzle.  In my case, between the metering pump and nozzle.  I remember reading somewhere about a purge type setup where the solenoid closes a few seconds before the rest of the system shuts down to allow the pressure to be relieved.  I'll have to see if I can find that again.

Russ there is a Honeywell safety control for Becketts that has a programable post-purge. Ithink up to 4 minutes.It help dry the retention head. Not sure if this is what you were talking about but this oil burner guy is funny. https://www.youtube.com/watch?v=-vsiePKbH68&t=3s

Ohhh yea, that is a nice control.  I might have to get me one of those.  It sure gives you a lot of control.

I'm going to try this Thomas 2660 vacuum pump for my air source.  Matt (Mschindler300) is working on getting his burner attached compressor done, but in the mean time I wanted to get something quieter than my big compressor.  I was also having problems with my big compressor blowing the breaker.  Unfortunately everything is plugged into the same circuit, so hopefully this will prevent the breaker from blowing.  I have heard that these pumps (they work as a vacuum or compressor) will easily provide enough air for a burner.  I will report back how it works.

Hi Russ,
I was wondering if we could get a picture showing how you got the 2660 vacuum pump set up and any comments you have about it?  Was wondering if I should use a little tank with it or does it pump air straight to the nozzle and what's the max rating on the regulator you use?
Thanks!

No tank, just straight from the compressor to the regulator.  I use a needle valve on a T connector coming out of the pump so I can bleed off the excess air.  The pump does produce more air than is needed, so you could add a tank and on/off pressure switch, but it was simpler just to add the T and needle valve.

The pump works wonderfully.  It is quiet and power efficient and produces more than enough air for the heater.  I would never think of going back to a full size compressor.
