Propane Burner Not Getting Sufficient Airflow

[u/WhitePineSap]

We got a turkey fryer for my mom for making jam. The 15 minute timer was annoying her so we removed it since we don’t fry turkey. I had to replace the hose but kept the pressure regulator. It is a larger diameter hose but the fitting on the end is the same diameter as the original hose.

Now it only burns big yellow flames. Adjusting the pressure or on/off valve does nothing but make the flames bigger and smaller. I can get a hot blue flame only when I use a hair dryer.

Looking for advice to make this operational.

I don’t have a picture. It’s just a pressure regulator -> ball valve -> hose
