Serial Number Fitment Notice
Verify fitment by exact engine serial number and the correct Mercury MerCruiser electrical components / oil pressure sender / engine harness parts diagram before ordering. Fittings in this area can vary by thread, angle, sender style, harness layout, and engine package.
When This Part Needs Replacement
Replace this elbow when the original fitting is corroded, cracked, leaking, seized, damaged during sender removal, or no longer positions the connected component correctly. It should also be inspected whenever the oil pressure sender or related engine electrical component is being replaced.
Installation Notes
Install 8053281 / 22-8053281 only after confirming the correct diagram location. Inspect the sender, adjacent fittings, wiring harness clearance, and mounting area before reassembly. Use the correct sealing method where specified and avoid overtightening into small threaded ports or cast engine components.

Parts Desk Insight
The easy mistake with this elbow is assuming it is a generic 90-degree fitting. On MerCruiser engines, this part is tied to a specific sender and harness layout, so matching the exact parts diagram is the safest way to avoid thread, clearance, or sender-position issues.
