Please tell me this vehicle has one. If it does, where is it?

Any help is appreciated. I have a hard starting condition, no codes,
and we have to push down the accelerator a bit to get it to start. It sucks in winter'with remote start when remote start wont start because of this but now I suspect fuel filtering wich I understand is part of the fuel pump assembly on this year.

I have no issue buying new parts and doing it. I cant afford the time to take it in a shop right now.

Also, gas mileage has gone gradually down by about 4 MPG over a year.

Without a factory service manual, or all data subscription, my recommendation would be to contact a dealer and ask them if there is an access cover for the fuel pump, and if in fact the fuel filter is in the tank, not external.
The dealer with your VIN# can look at the exact model, & should be able to advise you over the phone.
Also have them check to see if there are any recalls for your vehicle as well.
I noticed that some rendezvous fuel tanks were being replaced by the dealers /recalls.

There is none.....you drop the tank for replacement......

I would be checking for codes, fuel pressure, and inspecting the f/p regulator before dropping the tank.......also make sure there are no vac leaks near the MAF....
