Beautiful, No? (Fuel system)

This is now the entire fuel supply system except for the hose that runs from the filter up under the engine to the tank:

The engine driven pump is just in out of sight in the shadows on the left.

Previously, the line from the tank ran up to the most inaccessible location in the engine room where the filter was mounted. Getting to it required unloading everything in the cockpit locker and squirming in headfirst. The line then snaked through to a hard to reach location for the fuel pump under the galley counter and the up under the deck and across the top of the engine and down. Why, why, do they build boats this way?

These are the switches for the fuel pump, now relegated to just priming, bleeding, and boost status:

The pushbutton is hot wired directly to the positive bus (with in-line fuse) so that the fuel system can be bled with the starting and master switches off. This also avoids having to listen to the engine alarms all the time the bleeding process is going on. The alarms only sound when the button is pressed. If the switch should ever short out or get pressed accidentally, I'll sure know it:)

The toggle switch turns the pump on and off permanently from a supply wire to the starting switch. These switches can be reached in a moment through the hatch that forms part of the companionway top step. If the fuel system ever needs a boost in a tight spot because of loading filters or other problem, I can have the fuel pump on line in seconds.
