Pingel petcock
Ok, so I know there's got to be a thread about this but when I search it I don't see anything. My tank is being repainted as we speak and I want to sap from the OEM petcock to a Pingel as I'm told they are the best. Question though, most the ones I see are gravity fed and my bike has a vacuum petcock. Can't I just swap them and pinch off the vacuum hose? Only difference is now I'll have to remember to shut off the fuel everytime I shut the bike down right? Whats everyones thoughts?

Even with a vacuum petcock you should always be manually turning the petcock to the 'off' position; the diaphragm, spring and seat have been known to fail and leak or remain open. Trust, but verify 
I've always swapped the petcocks for Pingel petcocks, a vacuum cap will be included with the petcock so you can pull the vacuum hose completely and cap the barb on the carb. You'll get in to the habit of turning the fuel on and off at the petcock, it's such a habit with me after all these years that when I bought my first FI Harley, a '13 Wide Glide I still reach down to turn the fuel off when I shut the bike down

I'd get rid of that EPA, GLOBAL WARMING'S MY FAULT, don't look at the diesels exhaust we can make some more money with this people: just ride pure! But if you decide to leave that money re-circulating system, pack a parts replacement, tape and ties kit or a raincoat and a book to read waiting for your tow?

That vacuum petcock is gravity feed also. The vacuum opens a valve and allows the gas to flow. They can actually restrict flow as they get old as the rubber get hard and doesn't move as far as it did when new. When I changed mine I noticed the engine ran better as the carb was being starved at higher rpm and under load when more fuel was needed. You will love the pingel.
