Review on 🛢️ Fuel Pump Assembly E3556M for 2003 Cadillac Escalade ESV, 2002-2003 Cadillac Escalade EXT, Chevrolet Avalanche 1500, Suburban 1500, GMC Yukon XL 1500 - TOPSCOPE FP3556M by Ron Collins

Used this in my 2003 Escalade EXT when my original pump died at 140,000 miles. Fits perfectly and works great. If you are doing this work yourself, you should also consider ordering replacement fuel lines. Also remember to set back and disconnect the fuel vaporizer (carbon canister) as you will need room to move the fuel tank around a bit before lowering it. Most importantly, don't forget to disconnect at least the smallest atomizer line before dropping the tank, otherwise you may (like I did) break the small atomizer fitting and replace the atomizer canister.
