Kohlar 5CKM21 genset not getting fuel

I finally got a chance to drop the gas tank to check the generator fuel line. What I found was a very slight cracking at the end under the hose clamp that attached to the elbow going into the main tank. If I put my finger on one end of the hose and drew vacuum on the other the the hose held vacuum. So the fuel line itself was good after 22 years but was cracked under the hose clamp just enough to allow air to be sucked in. If I was away from home and could have gotten to the elbow connection without dropping the tank I would have just cut off 1/2 in of line and reattached like I did with the fuel pump side over the years and it would have fixed the problem. But the line being that old and about a foot short I replaced with a new line. Dropping the tank was not as bad as I thought it would be. Mike Brez on this forum let me borrow his motorcycle jack which made it easier. Now the only other problem is my remote switches don't work. I will start another thread for this issue. Thanks for all the replies.
