First, does anyone know of an electric fuel pump
designed to pull fuel
uphill about 4 feet? That can pull fuel
up through an unprimed line like a water pump
does? If so, the next part is unnecessary since I already have the fuel system setup for that.
If there is no pull type fuel pump
and there is only the push kind, I have a mess to figure out.
I have 3x 50 gallon below decks gasoline tanks
. The fuel level in these tanks
is about 4 ft below the "pump/fuel fitting/filtering or fuel management compartment" which is a box on deck
ventilation/discharge in the event of a fuel emergency
. Picture it like a propane
locker. Holes to drain any malfunction
away from the boat
The locker on deck
contains all fuel hose junctions/fittings. It contains a Parker fuel/water separator and filter. It contains a manifold of ball valves to select which of the 3 tanks supplies the fuel filter
. After the manifold is the fuel filter
. After the fuel filter is the standard automotive electric
push fuel pump
. It kind of works, but I'd like it to work
a lot better. Loses prime badly.
On the other side of the fuel pump
are direct fuel lines to both outboards and an outside generator
. I should also mention the fuel lines from the tanks to the manifold are all direct. There are no fittings or ways for any fuel lines to leak except inside the "fuel management" compartment on deck and vented overboard
Sticking to a "push only" fuel pump, I have to get 3 of them and introduce dangerous connections down in the hull
as far as I can tell because they are supposed to push fuel from below the tank level. I want to keep all connections in the fuel management box for safety
, which is 4ft above the tanks.
How can I achieve this?
