And it's half the price!
CARB got into the small gasoline engine regulation and banning business about five years ago. They were mostly going after the leaf blower, edge trimmer, yard maintenance small businesses, but it bled over to any "small" engine. The fuel pump in my RV generator was failing. The only pump approved by CARB was OEM and $175. The same pump was on Amazon for $25, but not CARB approved so Amazon wouldn't ship it to California. I found the same rebranded fuel pump on eBay for $15, and the seller didn't care where he sent them. I bought two, but haven't had to use the spare in over four years. I've also gone around California regulations by having stuff sent to my buddy in Idaho, who then holds onto items until we meet up, or he sends them to me. It's only illegal for a business to send unapproved items to California.
