Hi Paul, I'm glad to assist you. This fuel pump fits the Chevy Tahoe 5.3L with a FLEX engine, VIN "0", zero (from the 4th up to the 8th character of the 17-character VIN). For us to double-check and be accurate on the part you need, please provide the complete information of your vehicle (year, make, model, submodel, and engine size). The VIN would be much helpful.
