2015 c7 fuel pump problem

[sambasi]

My c7 fuel pump in the tank is making a screaming noice and if I pull over 3.5k rpm
it goes into limp mode with low rail pressure. I’ve change the filter and it’s the same. It’s looking like a new pump/sender unit needed. My question is is it a tank out or is there a access panel under rear seat base? As anybody else had any issues like this.. cars only covered 46k.

Cheers

Strange to have a pump failure at such a low mileage. If you have confirmed it is the pump then yes simply lift the rear seat base; Quick short but hard jolt upwards from either side will release (break) the catches and allow you to access the fuel pump. Remove the access panel to get to it. Make sure you release the excess pressure first
