So I bought the 73mm c&L MAF and it's supposed to have a purple calibration tube for the 30lb injectors. But I took the sample tube out of the maf, and it's solid aluminum, with a small bit of sharpe marker on the back (kinda looks purple).
Is there supposed to be a plastic insert in the sample tube with the different colors? Or is it just the shade of marker they put on the back of the tube. Pictures attached.
