I changed the impellers a couple weeks ago. Not too bad if you don't mind standing on your head for an afternoon! The whole job is about a 12-packer. The second engine definitely went faster than the first. Here are the basic steps I took:
1 - Pull blue plugs and drain system.
2 - Remove serpentine belt
3 - Remove idler pulley/bracket
4 - Remove two rear hose clamps and hoses
5 - Loosen Cool Fuel module (makes it easier to wiggle sea pump out)
6 - Remove the three bolts/nuts that secure sea pump bracket
7 - Remove sea pump/bracket assembly
8 - Swap out the impeller

Use liquid dishsoap as a lubricant. Getting the new impeller installed can be a b!tch. I used a large zip tie to collapse the fins on one end enough to get it started in the housing.

Changing the fuel filter is a piece of cake. Just three small bolts and the cartridge comes right out. Have fun!
