Installation Notes and Tips

Verify the hose routing before removal and compare the original shape, length, and end style to the new part. Clean the mating ports at the PCV valve and intake connection so the push-in ends seat fully. Confirm the hose is positioned away from sharp edges and hot components, and inspect nearby breather and vacuum lines while servicing the Toyota Tacoma emission system.
