You had told me that you were looking for a brass float.
The part number for the QJ float is 7046300. However it is not brass.
As far as I know,l Q-Jets, all used NitriFill floats. Brass floats are aftermarket replacements installed by people who don't know correct Q-Jet setup.
If you should put in a brass replacement you should set the float height at a different level due to the weight of the float.
The original float on very early (back in the 60's) QJ carb was a 7034454 but they did have problems with it becoming fuel logged. When those are replaced with the 7046300 it was necessary to set the float about 1/16" higher because the float is larger than the original one. This was before the time of the GMC motorhomes though.
I know there are brass replacements but they really are not needed as the 7046300 should never get fuel logged.
