I've been working on the LP system of my 1999 Coleman Westlake with the High-Pressure outside stove. I replaced the tank and installed an ACME hose fitting, but I've been having trouble with the outside high-pressure stove not working right. The P.O. mentioned he had to replace the High-pressure regulator, but it appears he used a 30 PSI unit. I've seen multiple references here to a 16 PSI regulator. My high-pressure oven is spilling gas and creating a kind of fireball when used. I'm assuming this would be my problem? What regulator would you guys recommend? A 2-stage unit to combine both together in one? Or do I need to keep the setup with two individual regulators?
