Bought this over the others with more reviews because it came with an extra “seal”. Very pleased with the product, I was lucky not to get one broken; accidents do happen during transport. If you have never replaced this before I suggest you buy the basket removal tool, this seller sells you a kit with it as well. If you don’t want to then you can use a screw, driver, and a plier to remove it (just like I did). If you see the my image with the old seals you can see the screw I used in the lower right hand corner next to the disposables. Make sure it doesn’t over fit, screw it in 3-4 times, wiggle it around, and pull straight out with pliers. If you google it you can see video demonstrations. Flush the basket hole with brake cleaner before inserting the new basket. I suggest you use an 18mm socket to place the injector (if you have the same as I) as you need to hammer the basket back into it’s hole (See 3rd image). The seal installations were a no brainer, except for the “seal 302”. I don’t know what it’s the purpose or how to put it in, since is not elastic and won’t fit. What I did was cut it in the notch and use it to keep track of the ones I had finish as I went along. All in all it was worth it as I did not have to spend hundreds of dollars on a new set since mine was just leaking gas.Hope this help.
