Fitment
This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.
What it does
Thread type and size must match on both sides; AN, NPT and metric threads do not mix. The right fitting, thread and size keeps a connection sealed and secure, which matters most on fuel, oil, coolant and brake lines.
Installation & tips
- Confirm thread type and size on both sides, and use the right sealant or none as the fitting type requires.
- Hose: Match hose size to the fitting.
- Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
