    Very well made

    I was very happy with this filler neck both because it was not the cast tube sold by most other places, and the price was very good. The cap appears a bit cheap by seems to be functional.

    Nice product but......

    Very well made fabrication, welds look nice. The only issue I have is that the pictures show a nice looking radiator cap. I was disappointed that it wasn't included. The ad could be better if they made the cap an option.
