1987 CMX450C Rebel carburetor hoses?

Good morning,

I'm in a huge pickle with my first bike, and I'm really hoping someone can help out! Does anyone happen to have photos on where the hoses are meant to go from the petcock valve and the carburetor for the 450? I've seen quite a few photos of the 250 and its carburetor, including where the hoses are going. I've tried using the attached pictures, though I'm unable to accurately identify where the hoses are meant to hook up. Imagine all the hoses completely detached, and that's the situation I'm in. This bike was suspected to have had carburetor issues, and I had it removed/cleaned/reattached. Prior to it's removal, the hoses were clogged, dry rotted, or just altogether missing. Up to this point, the spark plugs have been tested (they work), the carburetor is clean, and the only problem is that there's no fuel flow to the carburetor.

The 450 has a vacuum operated petcock. Engine vacuum allows the fuel to flow. Sending you a PM that may (or may not) help with the hoses.

Thank you! I've been digging through the info filtercontrol sent via private message. This might be solved this afternoon (as soon as I can get some new hosing!) I greatly appreciate both of you responding so quickly!

Guna, I can't yet see your photos via my mobile device, I'll give them a look as soon as I get a better signal.

Thank you both for providing the information! Those photos worked wonderfully, and I was able to get new hoses on the bike installed. I still am not able to get the engine to start after correctly routing the hoses. There's no vacuum effect on the petcock that allows it to provide fuel flow. Unfortunately, I managed to break the guide valve that the vacuum tube connects to (on the cylinder head) trying to take it off and inspect it, and now I'm hunting for this part.

You could check with Jack's Rebel Warehouse. He's the go-to guy for used Rebel parts.
