After 86, 000 I finally replaced my fuel filter with an aftermarket one ($14.00-Amazon). My fuel lines were still soft and supple. I DID NOT replace the bottom gasket (pump assembly to fuel tank). I did not replace the gross particle filter on the end of the pickup tube, either. Removing the fuel tank and inverting it makes it much easier to remove the bigger chunks of debris that ends up in the tank. Removal of the sender/pump assembly is made easier if you fashion a small wire hook to pull up on the float wire and help guide it through the opening. This is not a difficult job, so long as you are comfortable working on your own machine. Lay the inverted tank into a "nest" of soft material to keep it steady and to keep it from getting scratched.
