No gas coming out of KLR 2008 tank.

Hello all,

New to this forum and hope someone can help. I have 2008 KLR and pulled the gas tank off it to put in a new spark plug. As it turns out I did not have the correct socket for the spark plug so skipped (temporarily) replacing the plug and just put the tank back on.

I put the choke on and tried to start the bike after putting the tank back on. It did start fine, and ran for about 5 or 6 seconds then stopped. Since then I can not get it started again. It turns over well. It seems to not be getting gas.

I opened the drain screw on the carb and no gas comes out. I detached the gas line from the petcock on the tank and no gas comes out of the petcock at all. Regardless if it is set to 'on' or 'reserve'. I have filled the gas tank to the top still no gas coming out of the petcock. I removed the petcock assembly from the tank and it looks clean and functional.

What am I doing wrong ? Any help would be greatly appreciated.

Petcock is vacume actuated. Check your vacume line from carb to petcock.

Also check that the tank breather tube isn't pinched (it would act like a straw with your finger over the end).

Ahhhh ok, things are becoming clear now. I see a connection on the petcock for what looks like another hose it is a horizontal connect, beside the downwards pointing connection for the actual fuel line. I did not notice that there was a line coming from the carb to that vacume connection on the petcock. I must have pulled this line off when I pulled the tank off.

Can you give me an idea where on the carb the vacume line should be attached to please?

Mine has been converted to manual petcock, but there's a picture in this post of what it's supposed to be connected to.
