Helping a friend with a 2003. 280 sundancer. Engine sputtering. Changed the spin on filter. What is this one ( see picture ) ? Anyone have a part number?


Thanks

The marine version will be built to different standards (stainless steel and thicker gauge) but it essentially the same GM fuel filter that can be had at most auto parts store. I did have the internals break on my 280 and it took me a few weeks to diagnose as there was no leak, and the sputtering only occurred at higher speed (fuel flow). IMO it's a good item to change every couple hundred hours.
Mercruiser/Sierra makes the marine version which I would recommend over the auto version.

EDIT

This is the lowest price I could find...
