Used this to replace the original leaky petcock on my Grande, works like a charm, no leaks with the aforementioned o-rings installed.

Great petcock

This is the one I use on all my Grandes that need new Petcocks. The handle is long and metal not plastic like most. The petcock fuel filter will fit if you jam it in. I will not remove that filter, it was built in for a reason. It's a tight fit but it will fit in the Grande frame.
WARNING - There are 2 small plastic white/clear o-rings that goes around the inline fuel filter. Those o-rings are necessary for the petcock to seal to a Grande spicket. Without those 2 pieces the Petcock will leak. Keep the o-rings in place and it's an amazing petcock

Fits Grande

Yes it fits, but you must re-use your old filter. DO NOT revmove the filter from the petcock! The filter does two things. One is it filters gas going to the carb of course. The second is it prevents the petcock from clogging! Simply unscrew the nut from the old petcock. Use an old toothbrush and brush the bottom of the filter where it meets the cock. Twist the filter off with your fingers. Next, twist off the new filter. You must then cut a small section off the clear stiff hose on the cock. Look at the old and measure from that. Then screw on the old filter to the new cock, finger tight. You're done!

Vespa Grande Petcock

This is the one you want for your Grande! I pity the fool that buys the wrong petcock... you want the fuel to flow straight out.. not up or any other weird angle. The filter is about an inch too long... no biggie, just remove it and buy an inline filter.
Excellent Replacement Petcock for Grande
