My 2008 Ranger 700 XP has a "dead spot" when accelerating that feels like it is starving for fuel. I went by the dealer and found out no servicable fuel filter is sold, and you have to buy the whole tank assy. He also said the TPS sensor could be bad, but he did not have time to check it and you have to have a regulator to set it up. Does anyone know of any aftermarket parts that may be available to upgrade the fuel tank or filter? Also if anyone had bought or made that regulator what is the cost. I can fix this thing myself, but I have never worked on one of these and need a little advise.
