This filter says it is a water separator and it is under the front just aft of the steps. The photo is taken from between the steps. I can't tell for sure what it's for.
That is a Generator filter RT-12. The Same one as your Aquahot Filter in the drivers side 1st compartment.
Thank you Barry. Is that the only fuel filter for the generator?
Yes it is and think the R12T is a good number for the Racor filter and price is in the $15.00 area for the replacement element
There is a second fuel filter
