Fuel is not necessary to set the pressure.

If you can't get more than 2.5 you either have an air leak or the rotor/vanes are worn. Remove the airline from the elbow at the pump and plug the elbow, run the pressure screw all the way in. If the pump is OK and there are no leaks the pressure should go up to about 10 psi.

I have 2 heaters that will run out of fuel when tank is still half full

What size LP tank are you using? If you are running (2) 175,000 btu heaters on a tank that is too small, especially in this cold weather, it will not have enough vaporization to keep up with demand. This will cause the outside of the tank to frost up and the pressure inside will be too low to run the heaters. You need more wet surface area, i.e. a bigger tank or just manifold 2 tanks together.

I Have an old M30 REDDY HEATER, It won't start, Good Spark, Good Fan, Clean fuel, Pump has some pressure- I have no-idea on how much is needed, Not sure about the in-out of fuel lines to the Main Jet...

The line from the pump to the nozzel should go inthe front fitting and the one from the tank goes to the backfitting. If either of these have cracks in them or do not fit tightly over the fittings it will not build enough pressure and burn. You may also check the filters mainly the output filter as this will also effect pump pressure. I don't have as much experiance with that brand so I can't be sure exactly about the pressure. I think it should be 3.5 to 4 Psi. If this doesn't help please email me and I will find out for sure.

I have a heater that isn't picking up fuel. Someone had taken it apart before I got it and lost 2 of the tabs off of the impeller. I did replace it but to no avail. Any suggestions?

If it isn't picking up fuel you need to check the pump pressure. I am not familiar with that spacific brand but if it is the same as a Dayton the pump pressure should be about 4.5 psi. or within about 1 psi. If you know it has enough pressure check the fuel filter then check the lines. If the hoses have are old they will crack and cause an air leak which will prevent suction. So if the hoses show any signs of cracking replace them. Pay particular attention to the ends where they slip over the fittings. If they are not tight it will leak air and any air leaks result in reduced suction.

Dayton 70,000 btu kerosene heater only runs consistently with 3/4 of a tank of fuel or more. Once it is below 3/4 it keeps shutting off. I have cleaned filters, tried to set pressure but pressure won't go...

If you can only get 4 psi from the pump then you have a problem with the rotor. This could be from the vanes not coming out properly of if you have replaced or serviced the rotor you may not have the clearance set properly between the pump ring and the top of the rotor.
Make sure to inspect the pump cover for any small cracks..

If you pump pressure in not enough the unit will not be able to pull fuel from the tank and you will see the burner cone slowly start to go from the orange color to a dark color and the unit will shut down.

Is there a Desa heater repair facility in York Pa

most likely the fuel pressure is wrong. you need a fairly accurate gauge to reset it. there are two screws in the back of the heater, one is a cover for the gauge port the other is a regulator to adjust the pressure, the pressure is set between about 3 and 6 psi depending on how many btu s your heater is. bigger heater bigger psi. for example a 60k btu heater is set at 3.4 psi. these gauges cost 30-40 bucks online, but if you have a welding supply store or a northern tools nearby you can usually find an inexpensive acetylene gauge that will measure that fine and at at that low a pressure. all you need to do is make up a little adaptor to fit, parts also available at same store. mine cost about 7 dollars all in. the pressure setting is critical on these heaters, you cant swag it, you really have to have a gauge and set it.

Seems that my R-40 is not pumping fuel

You must set the pressure! If the heater runs with your compressor connected, but won't when the pressure is disconnected, well.......

Setting the pressure is easy!
