Installation Tip
Do not pre-fill the filter through the center hole (clean side). Install the filter dry and cycle the key switch on 3–4 times to allow the priming pump to fill the filter. If pre-filling is necessary, pour fuel into the smaller outside holes (dirty side) so it passes through the media before reaching the clean side.
Verify your engine serial number and configuration before ordering to confirm fitment.
