This is a required tool to remove the fuel line connector from the fuel filter on E85 C/K utilities with 5.3L V8 engine (PRO L59).
Due to the limited clearance between the fuel line connector and the fuel filter, each end of the release tool must be twisted and turned before inserting it into the connector.
Suitable for Suburban, Tahoe, Yukon, Avalanche, Silverado and Sierra from 2002.
