Its hard to do - you should remove fuel tank. I was looking for a more detailed answer, Hard to do doesn't really tell me much, Just saying it's hard doesn't really work for me. I am a good mechanic whats hard to most prolly doesn't apply to me. Does anyone actually know whats involved? OK.First ,you should stand gator on hoist,then remove 4 nuts and tank skid plate and all pipe across(you need special tools 310-D005 and 310-123,try search on e-bay).Second,use suitable jack for support the tank(be careful,dont stend jack directly beneath fuel pump mounting area - middle of tank) and remove 2 bolts and front and rear support stripes.Lower front tank side appr 1 in. and dissconnect vent tube from fuel pump module.Then,disconnect the fuel pump module and electrical connectors,remove tank from the gator.Last,use special tool 310-123 to remove fuel pump module. P.S. If you have any technical qestion write dyrectly rufnack1975 dog Yahoo dot com.
