This is an OEM item and so it will fit with ease. These can sometimes become blocked which can cause a build up of water within the pipes that run through the fuel tank. If that happens, you may find water is then deposited into your fuel which is never a good thing.
Please see this short video we have produced explaining just such an occurrence and how it was sorted.
