What is the size of mounting holes??
Sierra (who bought out Mallory) does not have that info. You will need to make sure it cross references with your OEM number. If you need some assistance cross referencing call us at 1-800-914-1123.
My fule lines are 3/8 id, will this filter work for me ?
Sierra cannot match it up by measurements. They can only match it up by engine application. Contact us at the number at the top of the page for more assistance.
I have an older boat, it has a water fuel separator filter (probably original). On the front of the filter, clearly states Sierra 18-7848, on the back, states "replaces OMC (174144). Is this the right filter? On the front, there is only 18-7848, there is no -1 at the end. Thanks?
The "-1" indicates packaging only. It is the same part.
Can youbuy just the filter or does it only come in a kit?
Filter is 18-7844.
