I suggested a larger O-ring, and within a week, I received two new caps with larger O-rings. Now, the cap fits securely, and I have two spares as a bonus!"

"I have a Craftsman M260 mower, and the gas cap would loosen while mowing. After comparing it to the original cap, I found it was a bit loose because of a thinner O-ring. I decided to replace the O-rings with some I purchased, and now the fit is snugger than ever. If I had known earlier, I would have just swapped the O-ring on my original cap!"

"I got this gas cap because my old one was leaking gas. Briggs and Stratton told me the gasket wasn't replaceable, so I ordered this one. It fit well, but I later discovered it lacked a seal, which made it not ideal for my needs. Now, I'm unsure how to resolve this issue."

"I lost the gas cap on my push mower and needed a replacement. I searched by my mower engine model, and it said this cap fit my mower. It went on fine but created suction and stalled the engine. I drilled a small hole through the top of the cap for venting, and it works great now."

"While the cap fits well, I've noticed it has a snug round sleeve that can rotate around the cap. This sleeve is supposed to hold the cap securely, but after just a few weeks, it has become tighter. This could potentially cause the cap to open unexpectedly while in use, which is a bit concerning."

"The design is a bit frustrating because I can't tighten or loosen the cap without removing the entire assembly. This isn't how it should work, which is why I gave it a one-star review."
