check engine light

What is your question?

for seveal months, my low fuel light has been going on and off even though i have a full tank of gas. now my check enging light keeps going on and off. i took it to auto zone and they put the machine on it and the code is p0452. fuel tank pressure sensor condition. connectors, wiring, hoses and fittings are ok. so, does this mean that i need to replace my fuel pump?
