Here is a link for INCA molded products- they were the OEM for tanks on the 92 Vs-- can't say if they provided tanks before or after but thought this might be useful. I was able to find the model and serial number LABEL on the the top of the tank. Had some seepage around the sending unit and was able - thankfully to repace just the unit to fix the problem. These are cross poly link tanks and are OK with ethanol. Was surprised to find that my 93 Evinrude Ocean Pro 150 was rated for E10- someone was thinking ahead!
