Default carb leaks

02 XLH 883 stock 21,000 miles carb is leaking from the over flow tube on carb I recently replaced the petcock, no vacuum plugged that a long time ago,however when I turn on fuel from petcock it starts leaking does not leak while driving?
Is this a vacuum leak issue or float issue?? Thanks in advance

Did you replace the vacuum petcock with another vacuum petcock or a Pingle type with no vacuum port? Might wanna clean the carb and adjust the float height.

Where's it leaking from? Might be a cracked fuel line.

Float needle probably has a particle of dirt lodged behind it .Invert the carb and blast it out with a carb cleaner spray .

Carb rebuild kit very easy. I had a 2000 - 1200 that did that.

Float.
It's able to keep up running. However, not a good idea however. Nor is removing the vacuum petcock.

Now you know why you should always turn off fuel. And Harley even says to do vacuum one . Harley's old single diaphragm one can go bad.

For those who do keep it. Pull a vacuum ever oil change on it. It needs rebuilt if it leaks. It can pull fuel into manifold leaking.

Newer ones have a double diaphragm. They don't leak.

Hey thanks for the info,
I did change out the VOES petcock for a standard, it works great however upon taking the carb apart the float was stuck makin the gas hit the overflow

I bought a petcock non vacuum for my 1998 and haven't had no issues. I never turn my fuel off when parked.
