Saddle tank siphon primer

A fuel delivery system comprising:

• (a) a fuel tank having at least two sections;
• (b) a fuel pump disposed in one of the sections, the fuel pump having an inlet disposed adjacent a bottom of the fuel tank;
• (c) a pick-up disposed in another of the sections remote from the fuel pump, the pick-up disposed adjacent a bottom of the fuel tank, the pick-up including a check valve;
• (d) a fuel supply line connected at one end to the fuel pump and at another end to the pick-up, the fuel pump supplying liquid fuel via the supply line from the section containing the fuel pump to the section containing the pick-up;
• (e) a siphon line connected to the pick-up at one end and terminating in the section containing the fuel pump at another end;
• and
• (f) the fuel pump providing a continuous flow of liquid fuel to the pick-up, to purge and prime the siphon line, the check valve opening to allow transfer of liquid fuel from the second section to the first section and closing to prevent reverse flow from the first section to the second section.

A method of delivering fuel to an engine from a fuel tank having two sections, a first section including a fuel pump and the second section including a pick-up, the pick-up having a housing, the fuel pump and pick-up connected via a fuel supply line and the pick-up connected to a siphon line at one end and terminating in the first section at another end, the method comprising the steps of:

• (a) transferring liquid fuel from the fuel pump in the first section via the supply line to the pick-up in the second section and to an engine via an engine supply line;
• (b) priming the siphon line with the transferred liquid fuel purging any fuel vapor and air from the siphon line;
• and
• (c) transferring liquid fuel from the second section to the first section such that a substantially equal level is maintained in the first and second sections.

A fuel delivery system comprising:

• (a) a fuel tank having two sections;
• (b) a fuel pump disposed in a first section, the fuel pump having an inlet for drawing liquid fuel from the fuel tank and an outlet for transferring the liquid fuel through a filter, to a pressure regulator and then to an engine and to a pick-up;
• (c) a pick-up disposed in the second section;
• (d) a fuel supply line connected to a tee at the exhaust of the regulator at one end, and to the pick-up at another end;
• (e) one portion of the tee ports the exhaust fuel to the supply line for the pick-up, the other portion of the tee ports fuel into the first section;
• (f) a siphon line connected to the pick-up at one end and terminating in the first section at another end;
• and
• (g) the fuel pump providing a flow of liquid fuel to the engine as well as to the pick-up, whereby the siphon line is primed with liquid fuel to normally provide a substantially equal liquid fuel level in the first and second sections.
