The difference between 18-7989 and 18-7789 how many microns are each and will either fit my 1997 Larson 226 LXI Volvo Penta 5.7L GS. motor?
We would need to know full engine model number or serial number to match it up because we would have to cross reference. The difference is 18-7989 is 10 micron and the 18-7789 is 21 micron. Contact us at the number at the top of the page with that info we need to cross reference parts.
