I have a 06 Ultra Classic 88" fuel injected motor. when its running it sounds like I have a vacuum leak from the front of the engine. Any ideas what it could be?

 

Exhaust leak maybe, does it run fine?

 

Yes it seems to run fine I think I figured out what it is. I thinks its the fuel pump, should it be that loud?

 

Maybe you have a pinhole in one of your lines inside of the tank? https://www.hdforums.com/forum/dyna-...fuel-line.html
