How to tell if your fuel filter was clogged?

I changed the fuel filter on my 01 Pontiac Grand Am and dirty fuel came out the inlet side of the filter and clean fuel came out the outlet side. Is this common of a clogged fuel filter?

A clogged fuel filter would not provide the proper fuel pressure and fuel volume per unit time even though the fuel pump was functioning properly. Dirt in itself does not mean any filter is bad, including air filters, fuel filters, oil filters etc. In fact, when a filter starts %26quot;loading up%26quot; with particulates (dirt etc), it actually filters better than when it's brand new as long as the minimum pressure and volume are maintained. You can often get 80,000 miles use out of a fuel filter and it will still be providing the pressure and volume required. However, if you run your tank dry, water and sediment from the bottom of the tank can be pumped up into the filter, so it's recommended that you change the filter if you run out of fuel.

if the filter is out side the fule tank then just take the filter loos and check the presser from the fule pump if you changed it and you thing the new one is pluged make shure you put it on the right way thare shood be a flow arrow on the filter hope this helped
very common .you could blow threw it and then blow threw the new one and compare ,or you could cut the old filter up and see how dirty it was.
