    Really high quality

    The CNC quality of the cap is really good. It has a good weight and a good fit. I don't see this cap cracking when removing after a few thousand miles!

    I was really surprised when it showed up in the mail. Solid, heavy duty, with beautiful machine work. I regret not buying this sooner.

    Replaced my cracked plastic fuel bowl cap with this beauty. Now riffraff just needs to make some fuel caps in matching colors

    Really great machining and the blue anodizing looks great. Easy install, no leaks. I recommend them to anyone with an OBS truck.

    Another Top quality part from Riffraff this piece of aluminum is a work of art to say the least. Anodizing looks perfect and fit and install went flawlessly! I recommend changing out the Ford fuel filter while doing this install might as well.
