Installation Notes and Tips

Verify the vehicle uses a hydroboost system before ordering, since the fitment is specific to pump-to-hydroboost routing. Confirm the 16 mm male O-ring and 18 mm male O-ring end fittings match the original hose connections, and compare the 53.9 in. overall length to the removed part. On 1999-2002 Chevrolet Express and GMC Savana applications, part number 3401842 should be matched to the exact brake and steering configuration shown in the fitment data.
