Remember, gasoline is gross, doesn’t taste good, and is flammable, so be sure to exercise extreme caution. Leave any rags or towels long enough to dry outside before disposing them, and NEVER throw any old fuel or rags wet with gasoline into the trash. a fuel filter acts as a barrier, keeping potentially damaging elements from playing havoc on the rest of your vehicle. Since it does undergo a lot of heavy use during the regular lifespan of your vehicle, it slowly gathers and holds those contaminants, and eventually, if not attended to, will begin to restrict flow and eventually plug up. Fuel filters on older cars will often last one and a half to two years. The good news is that fuel filters can be a relatively affordable part, especially if you buy the parts and do the work yourself. A new filter can cost as little as around fifteen dollars.
