how to locate and replace fuel filter
fuel filter on 2004 Audi A4 Quattro
i guess from this post it means you have a noise as i mentioned in the last post? the filter is under the car just ahead of the passenger side rear wheel. there are quick release hose ends that need to be squeezed to release and a clamp that holds the filter on the car. a few ounces of fuel will spill and the first line will spit at you so use a rag. pay attention to where the lines go!!! and to the flow direction.
