Guys, help naman po...

Okay lang ba DIY na lang fuel filter replacement? May I ask how it is done? My car is 90 corolla gl. Naka-carb. Tingin ko kasi it's supposed to be a simple procedure. Kaya lang mahirap mangahas at baka kung ano ang magalaw ko. Newbie pa rin lang kasi ako pagdating sa car maintenance. Thanks in advance.
