Hello all! I have a 2004 DVX 400 (suzuki motor) that i have apart and im just wanting to clarify my hoses for my carburetor. ill post a picture of what i have and if someone can just confirm. 1. is coming from the left side of the petcock! 2. is a vent tube 3. Im pretty sure is coming from other side of petcock?

Correct. 1 is vacuum to run the petcock. 3 is the fuel line from petcock. The vent tube hooks in to a couple of holes on the side of the intake runner, keeps it out of the way.

Ok Thank You. just wanted to make sure i put everything back right before i fire it back up

Can you run through that again?? I thought 1 is the main fuel line, line running from the tank to the carb and putting fuel in the bowl, 2 is a vent line, and idk what 3 is, that’s why I’m here, lol.

3 is for sure a vacuum to the right side of the petcock. 1 goes to the left side of the petcock which does feed into the bowl. 2 just a vent that sits in the frame.

Interesting. I’ve got an Amazon carb the dude who owned the bike before me put in, and when I plug the vacuum line (#3) it starts ti run a little better, but if I put a line to the peacock from it, it won’t run at all. It pulls fuel through the line, is it supposed to do that?? (If I need to make a new thread lmk)

What is the peacock turned to Pri or on?
