Anything with an access hole = cake.
W/O access hole = hard.
The fun part comes when you have to rewire the whole shindig because the factory wires have decieded to degrade and crap out. Lemme know when your fuel pump dies due to the extra voltage draw on the factory wires so I can go ahead and tell you how to wire it once so it won't do it ever again. Wiring a 255lph pump to stock wires is just waiting for eventual failure.
