2003 Chevy Tahoe Fuel Filter Replacement (FLEX FUEL 5.3L Vortec)

Today I Swapped out the fuel filter on my 2003 Chevy Tahoe
Should be the same on 2003+ Chevy / GM Trucks and SUVs with the 5.3L Vortec as long as it has flex fuel. You can determine if your vehicle has flex fuel by the VIN. The 8th digit will be a “Z” if the vehicle flex fuel.

Fuel filter part # 86623 (Carquest brand)

Tools needed:
5/8 Flare wrench
13/16 wrench
Drain pan ( will be some minor fuel spillage)
Lisle low profile fuel line disconnect tool

Lisle 34750 Low Profile Fuel Line... https://www.amazon.com/dp/B002BI2DU4?...

I also used a standard fuel line disconnect tool.
The Low profile tool is needed for the quick connect at the filter.
The swap can be done without removing the fuel line like i did, it was just easier for me
