Wanting to cone my fleetmaster, my question is what is the difference between the FM, TM and SM all coned w/low water pick ups. Are the internals different between the 3 models and what speeds can you run safely with a coned FM. Its on a 3.0L optimax DFI/ Allison GS. Next question who to send it to. Would appreciate any input, Thanks , Scott.
