Installation Notes and Tips

Clean the injector and rail sealing surfaces before installation. Inspect the injector body and rail for scoring, corrosion, or debris that could damage new seals. Lightly lubricate O-rings with clean engine oil or an approved fuel-system lubricant before assembly to reduce tearing during installation. Verify seal size and placement against the original components before reassembly. Fits 1995-1999 Cadillac DeVille, N/A, Rail Pack Fuel Injector Seal Kit.
