What tank is this?

Post pics of the device...and if you want a new petcock that will fit on a 78 tank measure the center to center on the bolt holes..should be 40MM. If it is, then the 77 and 78 750 petcocks are the exact same thing as stock except the fuel and vac nipples face different direction...but it will bolt right up.

And its about 1/3 the price of a 78 1000 petcock!!

Is this a good enough pic? Not sure I want to replace it yet, I think. Ill try and fix it first..

That's not the 80 leverless petcock

The lever may not move due to being spray painted, or the gasket is just hard

Squirt some penetrating oil around where the lever goes into the petcock body

The one on the left is not OEM. It's a Pingel aftermarket valve.
