Abstract

A connection member for a fuel system comprising a body having an inlet configured to receive fuel, a first outlet fluidly coupled to the inlet and configured to release fuel from the body, a second outlet fluidly coupled to the inlet and configured to be fluidly coupled to a fuel injector, and a fuel path fluidly coupling the inlet, the first outlet, and the second outlet, the fuel path including an accumulator volume.

Claims (20)

WHAT IS CLAIMED IS:
1. A connection member for a fuel system including a fuel injector comprising: a body having an inlet configured to receive fuel; a first outlet fluidly coupled to the inlet and configured to release fuel from the body; a second outlet fluidly coupled to the inlet and configured to be fluidly coupled to the fuel injector; and a fuel path fluidly coupling the inlet, the first outlet, and the second outlet, the fuel path including an accumulator volume.
2. The connection member of claim 1 , wherein the inlet is positioned between the first outlet and the second outlet.
3. The connection member of claim 1 , wherein the first outlet is positioned between the inlet and the second outlet.
4. The connection member of claim 1 , further comprising: a fuel leak path having at least one fuel leak channel fluidly coupled to at least one of the inlet, the first outlet, and the second outlet.
5. The connection member of claim 4, wherein the at least one fuel leak channel of the fuel leak path includes a main leak channel, an inlet leak channel, a first outlet leak channel, and a second outlet leak channel, at least one of the inlet leak channel, the first outlet leak channel, and the second outlet leak channel being fluidly coupled to the main leak channel.
6. The connection member of claim 5 , wherein each of the inlet leak channel, the first outlet leak channel, and the second outlet leak channel are fluidly coupled to the main leak channel.
7. The connection member of claim 1 , wherein the fuel path includes a first portion having a first diameter and a second portion having a second diameter, the second diameter being greater than the first diameter.
8. The connection member of claim 7, wherein the first portion extends from adjacent a first end of the connection member past the second outlet.
9. The connection member of claim 7, wherein the first portion extends past the inlet and the first outlet and ends prior to reaching the second outlet.
10. The connection member of claim 1, further comprising a clamping plate positioned between the inlet and the second outlet, and at least one channel positioned between the clamping plate and the second outlet.
11. The connection member of claim 1 , further comprising a groove adjacent the second outlet, the groove configured for retaining a wiring harness clip.
12. A fuel distribution system comprising: at least one connection member having an inlet, a first outlet, and a second outlet; a first outer fuel line fluidly coupled to the inlet of the at least one connection member; a second outer fuel line fluidly coupled to the first outlet of the at least one connection member; and an inner fuel line fluidly coupled to the second outlet of the connection member.
13. The fuel distribution system of claim 12, wherein at least one of the first outer fuel line, the second outer fuel line, and the inner fuel line include a first wall defining a main channel of the line and a second wall defining a passage extending between the first wall and the second wall.
14. The fuel distribution system of claim 12, wherein the inlet and the first outlet are configured to be positioned outside of a cylinder of an engine.
15. The fuel distribution system of claim 12 further comprising a high-pressure fuel pump fluidly coupled to the at least one connection member and a pressure limiting valve fluidly coupled to the at least one connection member.
16. The fuel distribution system of claim 15, wherein the high-pressure fuel pump is coupled to the first outer fuel line and the pressure limiting valve is coupled to the second outer fuel line.
17. The fuel distribution system of claim 15, wherein the at least one connection member includes a first connection member and a second connection member, the second outer fuel line fluidly coupled to an inlet of the second connection member, a third outer fuel line fluidly coupled to a first outlet of the second connection member, the high-pressure fuel pump coupled to the first connection member via the first outer fuel line and the first outlet of the second connection member coupled to the pressure limiting valve via the third outer fuel line.
18. The fuel distribution system of claim 15, wherein the at least one connection member includes a first connection member and a second connection member, the high-pressure fuel pump fluidly coupled to the first connection member via the first outer fuel line and the high- pressure fuel pump fluidly coupled to an inlet of the second connection member via a third outer fuel line.
19. The fuel distribution system of claim 18, wherein the pressure limiting valve is coupled to the first connection member and the second connection member through the high-pressure fuel pump.
20. The fuel distribution system of claim 15, wherein the at least one connection member includes a first connection member and a second connection member, and the pressure limiting valve is positioned between the first connection member and the second connection member.
