Abstract
A leak detection module (LDM) includes a housing that provides a cavity that is enclosed by a wall that has a hole. A valve is arranged within the housing and in fluid communication along a passage that extends between first and second ports on the LDM, the valve is movable between open and closed positions. A pump is arranged within the housing and in fluid communication with the passage. A fluid fitting extends through the hole and has a passageway that extends between first and second end portions. The passageway is in fluid communication with the pump, the fluid fitting provides one of the first and second ports. A fastener secures the fluid fitting to the wall.

A leak detection module (LDM) comprising:
- a housing providing a cavity enclosed by a wall having a hole;
- a valve arranged within the housing and in fluid communication along a passage that extends between first and second ports on the LDM, the valve movable between open and closed positions;
- a pump arranged within the housing and in fluid communication with the passage;
- a fluid fitting extending through the hole and having a passageway extending between first and second end portions, the passageway in fluid communication with the pump, the fluid fitting provides one of the first and second ports;
- and
- a fastener securing the fluid fitting to the wall.
A method of assembling a leak detection module (LDM), comprising:
- arranging a pump and a valve in a housing with a hole;
- orienting a fluid fitting in the hole in a desired position;
- securing the fluid fitting to the housing at the desired position to provide a port to the LDM;
- and
- enclosing the housing, wherein the fluid fitting in fluid communication with the pump and the valve.
An evaporative emissions system component comprising:
- a housing providing a cavity enclosed by a wall having a hole, the housing having first and second ports, the wall having first and second sides opposite one another;
- a fluid fitting having a passageway extending between first and second end portions, the fluid fitting providing one of the first and second ports, the first end portion has a flange against the first side;
- and
- a fastener is secured to the second end portion adjacent the second side to maintain the fluid fitting in a desired orientation relative to the wall.
