I’m pretty sure the gas filter is on the fuel pump like most modern cars nowadays which basically means you can’t service them without dropping the fuel tank. Suggestion don’t let the fuel level fall under a 1/4 tank so your not constantly sucking up the slime from the bottom of the tank. It’s also a good idea to throw in some gas treatment every couple of months.

I stand corrected LJ was nice enough to do a nice DIY if you would of searched.

It’s actually easier than I expected allot of cars you must drop the tank and then remove the gas pump to get to it.

It’s not required to do it.
