Was wondering what changes as far as flame tube, combustion chamber; and fuel delivery would be required for converting from propane to liquid fuel. Thanks for any help

If you used Jetspecs for the combustor , then it can be used for liquid fuel . The only difference is where the fuel spray will impact the flametube wall compared to the propane spray/s Have you read the relevant sections here jetandturbineowners.proboards.com/thread/680/diy-turbines just click on the icons

I have, but the icons don't show me anything. I may need to update my smart phone browser because as of a while back, jetspecs won't work for me either. It said unable to open file lol. At this time my air intake to combuster is at the primary section of my flame tube. Do I need to change that or can it stay the same? Thank you again for all the help so far I really appreciate it.

Yep , the icons are working for me .
Its never good to have the air delivery tube joining the outer can opposite the Primary holes, it tends to cause combustion problems as the incoming air forces the combustion to one side of the flametube, irrespective of the fuel type .

The air delivery is off center, but in the zone of the primary holes. I'm just not sure if the air delivery should be in between primary and secondary holes. I have read mixed info on this placement lol. As of now, air comes in, slightly off center of the combustion chamber. Introducing air through the primary flame tube holes. My injector nozzle sprays gas radially but at the rear of the last primary hole drilled pattern. Should my injector spray radially in the zone of the primary holes where air delivery is? So air, fuel, and combustion all take place in the primary holes area of the flame tube?

A "tangential" delivery can also create problems :-(
I always have my air delivered to the "bottom" of the outer can , into the space around the "funnel" at the bottom of the flametube, the air can then spread out and work its way up towards the Primary holes where hopefully it'll have spread out enough to provide equal delivery through all the holes .
For propane delivery the spray must be radially towards the Primary holes , for liquid fuels the spray nozzle will produce a cone spray , you want the spray to theoretically hit the Primary holes
