Crusader Oil Line Hose 6.0L — OEM Part RA045155
Genuine Crusader / PCM OEM oil line hose for the remote oil filter system on Crusader MP6.0L marine engines. Crusader’s factory parts manual identifies RA045155 as the oil hose running from the engine oil bypass adapter to the remote oil filter assembly. This is a pressure-side lubrication hose and is one of two hoses in the remote filter circuit — see the fitment notice below to confirm the correct hose for your application.

When to Replace
- Visible oil leakage at the hose body or crimped end fittings
- Cracking, hardening, or surface deterioration of the hose
- Swelling or softness indicating internal breakdown
- Abrasion damage or chafing along the hose routing
- Damaged or corroded end fittings
- Preventative replacement during remote oil filter system service on high-hour engines
Service Interval
- Inspect annually for cracking, swelling, oil leaks, and fitting condition
- Replace immediately if leaks or deterioration are found — this hose carries pressurized engine oil and any leakage should be addressed promptly
- Replace during remote oil filter service or any service that requires disconnecting the oil filter circuit
Installation Notes
- Inspect the remote oil filter header, bypass adapter, 90° fittings, and sealing O-rings while replacing the hose — see PCM O-Ring R047245 for the related oil-line O-ring
- Ensure end fittings are fully seated and torqued to the specification in the Crusader service manual
- Run the engine and inspect all hose connections for leaks while verifying normal oil pressure after installation
Technical FAQ
What is the difference between RA045155 and RA045155A?
RA045155 connects the oil bypass adapter to the remote oil filter. RA045155A connects the oil cooler to the remote oil filter. They are different hoses in different positions in the same remote filter circuit and are not interchangeable. Matching the hose by its two connection points — not by appearance or length — is the safest way to confirm the correct part.
Does this hose fit MP5.0L and MP5.7L engines as well?
Yes. Factory documentation shows RA045155 used in MP5.0L and MP5.7L remote oil filter diagrams in addition to the MP6.0L. Confirm the hose position in the lubrication system diagram for your specific engine model before ordering.
Parts Desk Insights
Best Use Case: RA045155 is the correct OEM replacement for Crusader MP6.0L (and select MP5.0L/MP5.7L) owners replacing a leaking or deteriorated oil line hose in the remote oil filter circuit. It is particularly well-suited for preventative maintenance on high-hour engines where rubber hose assemblies are being replaced as part of a scheduled lubrication system service.
Common Customer Issue: The most frequent ordering mistake is confusing RA045155 with RA045155A. Both hoses are in the same remote filter circuit but connect different components. Identifying the hose by its two connection points — bypass adapter to remote filter (RA045155) vs. oil cooler to remote filter (RA045155A) — is the safest way to confirm the correct part before ordering.
