Just go to the parts store and buy the set, very cheap, and all you do is put the right size one on the line and push it into the fitting. relive the fuel pressure before you do it. You can remove the fuel pump relay under the hood in the power distribution box, start the truck run it till it stops, leave relay out until filter is done. If the lines are rusted, they sell kits to replace them.
