Great fit, works as intended!

Solid, well made cap that has some weight to it. Snug fit, and came with an extra O-ring in case the original wears out or breaks.

Fuel filler cap is first quality and fits great. Thanks to Geno's for sending an extra gasket. That's what I consider to be great customer service. Looking forward to more purchases for my EcoDiesel.

fits a little tight for my big hands to wedge off the filler neck, hope its just cold weather making it so tight.

I bought the green Ecodiesel fuel cap to replace the cheap and flimsy factory cap. The new cap is much nicer. Exactly what I hoped it would be. The rubber O ring is initially tight so the first few fill-ups required a strong pull to remove the cap. After about 5 removals, it slides-off easier and is great.
