Jag, Are you talking about elevating the oil/diesel? I was planning on using a 50/50 mix of oil and diesel. I'm still trying to dial in my burner but I feel like it's never getting enough fuel to it. I usually have to close off the back of the pipe because it blows out the flame right away otherwise.

If you are having to choke off the air, then it's running too lean. The fix is more air pressure on that venturi or more pressure on the fuel tank to help push the fuel in. I choose to raise my fuel source. The top tank in my photo is 100% used motor oil, I don't cut it with diesel. And the bottom tank is jet-A sump fuel (diesel) I start on the jet-A, get it up to temp and introduce the oil while backing off the jet-A. Have you done a simple test with just water spraying into a milk jug? Shut the fan off, start your venturi sucking on bucket full of water raised up. Point the nozzle at a milk jug and spray for 10minutes into it. Measure the water collected and multiply by 6. You need to be spray water at about 1.5 gallons per hour. This is a good starting point for you. If you aren't spraying these kinds of numbers, your venturi setup needs more work. Took me a couple tries to get the mig tip shaped correctly to get it to pull water. If the water/air goes back up the hose to the water source and bubbles, you made a pressure washer. Keep at it. It's not the easiest burner, but once working, you too can laugh at the propane guys pi$$ing away money on fuel. lol That was my only source of inspiration to get it going. CHEAPNESS!
