Yah, I have used a couple dozen sets of them on my rehabs. Only 2 or 3 of them posed a problem like yours. It took me a while to figure out it was just a flaw in the tubes and not some other issue. I guess I should compare lengths of them and factory weber burners. My guess is they will be an 1/8" or so shorter.
