Review on Fuel Filter Chevy Duramax Engines by Chris Brazington

Add me to the list of Duramax owners who suddenly have a problem that won't start. My pickup in 2003 surpassed 200,000. A week later, during a severe cold snap, I encountered this problem. I watched some online videos and checked my truck. When I pumped the primer, fuel leaked out of the heater terminal. Removing and reinstalling the filter base took much longer than installing new o-rings. I agree with other reviewers who mentioned two-lipped seals. They fit just like the ones you're replacing with separate tabs. Use a few drops of oil and take your time. Check your work by squeezing the inlet tube with your finger and pumping the primer. If the vacuum cleaner pulls a finger, you're done.
