petcock replacement
95 Heritage. Is there more to replacing the petcock than just installing the new one and re-connecting the vacuum/fuel lines? Being careful not to get gas everywhere appears to be the only thing I have to give thought to. But even with that, I was gonna wait until I'm about dry before install. Just asking if there's something else I need to know or do. Thanks

Pull the gas line off of the petcock, install longer line and drain the gas into a suitable container. You will still have some gas in the tank, but not much. I have leaned the bike over to the right propped against something. Replace both the gas and vacuum lines. Be careful not to crack the fuel inlet elbow on the carby. Use teflon tape on the threads on the tank.
Oh, and no smoking.

I'd add that if you still have the plastic inlet on the carb, now is the perfect time to replace it with a solid brass inlet.
Also add that all of this is a bit easier if you prop up the tank a bit. Doesn't have to be much, but a few inches will give you considerably more room to work.
What petcock are you installing?

OP you will need to get a length of hose and siphon the fuel from your tank to a gas can.
I can't stress this highly enough.
Get a Pingle w/o that damn vacuum port!!!!!
You will have to run a new hose from your carb to your VOES to get rid of the T junction.
Probably a good idea to replace it anyway to avoid age cracks that lets air leaks into the vacuum system.

I'm kind of a purest. So I was gonna just get the petcock from HD. They do stock it and I did have a chance to check it out. Looks exactly like the original except they improved it...$90.
Personally, at that price I'm with THC: Buy a Pingel.

....why be concerned about getting rid of the vacuum port? I don't want to complicate what looks like a simple install. Whenever I try to fix what isn't broken...it.ends up broken.

He still has the vacuum operated petcock so that won't work, unless he pulls a vacuum on it.
Or you can get a length of hose and siphon the fuel from your tank to a gas can.

Get the Pingle. Cap off or replumb the unneeded vacuum hoses. If you want to be a purest, keep the broken original in a box.
