Serial Number Fitment Notice

Verify fitment by engine serial number and parts diagram before ordering. This fitting appears across multiple systems and engine families, so the correct application depends on the specific plumbing location, thread configuration, and original part number.

When This Part Needs Replacement

Replace this brass tee fitting if it is cracked, corroded, stripped, leaking, blocked, or damaged during hose, drain, fuel, or plumbing system service.

Installation Notes

Confirm the fitting location and thread type before installation. Use the correct thread sealant only where approved for the system being serviced, and avoid over-tightening brass fittings, as threads can distort or crack under excessive torque.

Parts Desk Insight

Small brass fittings are easy to match incorrectly by appearance alone. Thread size, male/female layout, and system location all matter, so matching the original part number and engine diagram is the safest way to avoid leaks or installation issues.
