You may need to fill up the tank before returning a rental car at this airport following the "full out/ full return" fuel policy. In this case and in your interest, there is Galp petrol station opposite the new terminal building.
1. If you head to the airport from the A7 highway, take the exit "aeropuerto" through the road N338. Then in the first roundabout take the road N332 heading to Alicante.
You will be able to turn back in another roundabout and then reach the N338 road back again to the airport and the petrol station.
2. If you already drive on the N332 from any direction and heading the airport, just take the exit to the airport through the N338.
