Hi I'm about to change the fuel filter on the mk4 fiestas. Does anyone know whereabouts the filter is located and if there are any particular tips or tools I could do with knowing/buying before I start. Seems very simple according to the haynes manual although my only real concern is fuel spilling everywhere - it says to plug the fuel lines (what with?!) but am I right in thinking that without the fuel pump working then fuel loss will be minimal? Thanks
