    An easy to snap into place part. Wish I had ordered some of the fuel line at the same time.

    Small item, shipping cost more!
    This is the exact replacement part I needed. Fits like the old one. Part was $4 and change and shipping was $5! I am happy you are there to provide replacement parts as I couldn't find one locally. I'll begrudgingly pay the shipping to get up and running again.
