Yes it’s a plug and play. The most difficult part is getting the cap on and off, that’s it. The only recommendation is to keep the old cap close by just in case you are fighting to install the new one. I ended up having to use the old one and it worked great!

Hi Tim, I'm glad to help you out. Yes! It comes with a 1-year warranty. You can use the link below to order the part and take advantage of the sale price. I hope this helps. Happy shopping. https://www.carparts.com/fuel-pump/drivemotive/repa314514?can=cpab2020
