20 Most Recent 2007 GMC Envoy Denali Questions & Answers

Hello f poll: My name is Roger and I will help you. There is no fuel filter that you can easily get to. GM did not install a replaceable filter. The only filter for your GMC is located inside the fuel tank. To replace it would require removal of the fuel tank. What that means is this. When you replace the fuel pump you will replace the filter at the same time. The pump and the filter are a module unit. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger

Usually Kurt there will be a bracket on the tube that secures it to the engine block. Undo the fastener that secures the tube and gently pull upwards while rotating the tube out of it's press fitting. To install a new tube or when replacing the old one...select a box wrench that is just a little bigger than the tube diameter and slide it down to the bottom of the tube until it is pressing against the seating flange. Make sure the alignment of the bracket is close to where you want it to be and then gently tap on the edge of the box wrench to seat the tube. A long handled screw driver helps in tight quarters. Secure with fastener.
