Electrical connections for an integrated pressure management apparatus

A fuel system for supplying fuel to an internal combustion engine, the fuel system comprising:

• a fuel tank having a headspace;
• a fuel vapor collection canister having first and second sides, the first side being in fluid communication with the headspace;
• an intake manifold of the internal combustion engine;
• a purge valve including an inlet and an outlet, the inlet being in fluid communication with the first side of the fuel vapor collection canister and the outlet being in fluid communication with the intake manifold;
• and
• a fuel vapor pressure management apparatus including first and second ports, the first port being in fluid communication with the second side of the fuel vapor collection canister, and the second port being in fluid communication with atmosphere, a first arrangement of the fuel vapor pressure management apparatus occurs when there is a first negative pressure level in the fuel vapor collection canister relative to atmosphere, a second arrangement of the fuel vapor pressure management apparatus permits a first fluid flow from atmosphere to the fuel vapor collection canister when there is a second negative pressure level less than the first negative pressure level, and a third arrangement of the fuel vapor pressure management apparatus permits a second fluid flow from the fuel vapor collection canister to atmosphere when there is a positive pressure in the fuel vapor collection canister relative to atmosphere, the fuel vapor pressure management apparatus including:
• a housing defining an interior chamber in fluid communication with the first and second ports;
• a pressure operable device separating the chamber into a first portion and a second portion, the first portion communicating with the first port, the second portion communicating with the second port, the pressure operable device preventing fluid communication between the first and second ports in first arrangement, and the pressure operable device permitting fluid communication between the first and second ports in the second and third arrangements;
• a switch signaling displacement of the pressure operable device in response to the first negative pressure level;
• an outlet terminal fixed to the housing;
• and
• an intermediate lead member electrically coupling the switch and the outlet terminal, the intermediate lead member including a resilient element.

A method of assembling a fuel vapor pressure management apparatus, the fuel vapor pressure management apparatus including a housing having a main body piece and first and second cover pieces, an outlet terminal being fixed to the first cover piece, and a cover terminal fixed to the second cover piece and electrically coupled to the switch, the method comprising:

• attaching the first cover piece to the main body piece such that the outlet terminal projects into the main body piece;
• positioning in the main body an intermediate lead member including first and second end portions, the first end of the intermediate lead member contiguously engaging and being electrically coupled with the outlet terminal;
• and
• attaching the second cover piece to the main body piece such that the cover terminal projects into the main body piece, the cover terminal engaging the second end of the intermediate lead member and resiliently deforming the intermediate lead member.
