A complete new valve assembly isn't very expensive and you can often get one on eBay with a new generator included. It's not worth servicing the old valve given the safety implications of leaking fuel.

Do you mean unleaded? Officially no, unless it's marked "unleaded" or "dual fuel" (in Coleman speak, dual fuel means unleaded gasoline OR white gas) which means all the seals are rated for the additives in road fuel.
Unofficially yes, but gasoline is not a good idea because it tends to clog the generator with soot, it goes stale very quickly and it smells bad.
I would stick to Coleman fuel, Primus Powerfuel or Aspen 4. You probably don't get through so much of the stuff that cost is a big issue.

Orange or yellow flame is usually an indication of too much fuel, or not enough air mixture. Make sure all areas where burners would receive air from, are cleaned of spider webs, debris etc., and be sure when set up, nothing is close to it that would block that air flow from entering.

Have you tried to tighten the generator onto the valve assembly using pliers? This worked for me.

Here's the way these oldies work:
1. Make sure you've got fresh Coleman fuel or equivalent in the tank.
2. Make sure the cap is tight on the tank.
3. Unscrew the pump knob counterclockwise about 1/2 to 3/4 of a turn.
4. With your thumb covering the hole on the pump, pump the tank about 15-20 times, then screw the pump handle tight clockwise.
Then you can turn the little lever knob to the light position (I believe it is in the up position) and then crack the fuel knob open a bit and attempt a light of the burner with a lit match. As it warms up you can turn the lever to the opposite position to obtain a good flame...
Best to try this before you leave for your trip...

The pressure drops and so you have to pump it up a little every now and then. What I do is pump it up a hair. Reset the flames to a pretty blue. Yellow flame is too much fuel to air ratio. An air shutter adjustment is needed. Also dust in the burner can cause the secondary air to have an improper mix

My best answer is that your pump seals have dried out and are allowing pumped up pressure to leak back past the pump seal
Try this: DO NOT LIGHT THE STOVE
Pump it up hard then quickly attach a small balloon with a rubber band around the base of the pump - where it contacts the tank. A deflated balloon or a small plastic baggie - does the balloon begin to fill with air after a few minutes - if yes then your seal is leaking.
You might try taking the pump apart and soaking the seal overnight in fuel reinstall and see if it cores your problem
Good Luck
