Fuel burning in the tube due to an overly rich mixture or retarded ignition timing will cause it to glow. Are you sure it's only one tube? I had several glowing on each side at idle. I plugged a scan tool in and checked the short term fuel trims. They were in the -18 range on both banks meaning the PCM was trying to pull fuel out. Adjusted the injector offset in my VEC3 until they zeroed out. The glowing went away.
