Buying Guide: LB7 Fuel Filter Head Upgrades
What to consider when choosing a fuel filter head:
- Compatibility: Confirm LB7 engine year (2001–2004), Silverado/Sierra model, and whether the vehicle uses the 97780061/98017680 or 904-558 configurations.
- Complete kits vs. heads: If you want fewer install steps, choose complete assemblies that include the filter, water sensor, and primer.
- Material and durability: Metal housings tend to offer sturdier construction and longer life in harsh environments.
- Primer option: Decide between hand-primer pump or no-primer designs based on maintenance preference and service accessibility.
- Sensor integration: Water-in-fuel sensors help monitor fuel quality; ensure the sensor is included if needed for your setup.
