Where is fuel filter for 2012 Buick enclave
Thank you for writing in. There are many newer models that do not have a serviceable fuel filter. I believe the 2012 Buick Enclaves are one of them. They instead install a smaller filter on the pump inlet that requires servicing the entire pump, but are designed to last longer. Double check your owner's manual to see if it gives you any more information about the fuel filter for your specific model.
If the model was equipped with an in-line serviceable filter, you would be able to trace the fuel lines from the tank to the engine and locate it that way as well. Good luck!
