      I have 2008 Chevrolet Silverado 1500 LTZ Crew Cab 4WD, how do I check a fuel filter?

      Once you remove a fuel filter, you can tell whether it’s the source of your problem by a simple blow-test.

      First, attempt to drain all the gas out of the fuel filter the best you can. Find the inlet to the fuel filter (should be labeled as either “in” or have an arrow pointing to the direction of the fuel flow) and clean that inlet with a shop towel.

      Now, place a disposable rag or shop towel on your workbench, and gently blow into the inlet of the fuel filter, aiming down towards your shop rag on the bench. You should be able to easily blow into the filter without much resistance. With a plugged fuel filter, you won’t be able to. With a heavily restricted or clogged fuel filter, it will be hard.

      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. And i find that ORIGINAL PARTS GIANT( https://www.ebay.com/str/originalpartsgiant) provides a cheaper price on ebay

      Hello. checking a clogged filter is elementary simple. I check it with a pressure gauge. To do this, take a pressure gauge, connect it to the fitting located on the fuel injector. Start the engine. Measure the pressure of the combustible mixture. If the value is lower than the parameter specified by the manufacturer, then the filter is not working properly. So it was on my Dodge. Here https://davesoilchange.com/fuel-filter-for-duramax-diesel/ I found fuel filter for 6.6 duramax .Malfunction eliminated

      Interesting question.I think this is not a bad idea. I now have a problem with the Duramax engine, and more specifically with the fuel system.I decided to check the fuel filter with a pressure gauge. To do this, take a pressure gauge, connect it to the fitting located on the fuel injector. Start the engine. Measure the pressure of the combustible mixture. If the value is lower than the parameter specified by the manufacturer, then the filter does not work correctly. So it was on my Dodge.
