If you're not going to do the lines, the least you should do is drain all the old gas and replace with new plus dry gas, then jumper the fuel pump so it can run without starting the car to circulate the gas thru the filter without old stuff flowing through the injectors. Don't want to start it up right away as junk can flow into the injectors and mess them up. If you want to be careful, change out the filter after circulating the gas via the jumper before actually starting the car.
