Troubleshooting & FAQ

Q: How do I confirm this pump fits my Volvo Penta engine?
A: Cross-reference your engine model (3.0GLP-J, 3.0GLP-N, 3.0GXi-J, 3.0GXiC-J, or 4.3L/5.0L/5.7L/8.1L GXi-series) and original part number (3887373) against the compatibility table above. If your current pump displays OEM# 3887373, this replacement is a direct match.
