Yes, my buddy Peter has that same year and he tells me it is in front of the main gas tank and behind the other gas tank. Pretty much between the helm seat bases, maybe a few inches back.
If it is like the 2000, you should have this filler cap, and this pie plate, to access the FW pump and filter, on the front of the passenger seat box. The tank is under the forward deck hatch, covering the aux fuel tank space. A lot of storage space there if you don't have the aux tank.
thanks everybody.. I looked there before but I guess I didn't look good enough. my access plate is all the way forward on the cover so I guess I missed it.
