Abstract
A fuel vapor leak detection assembly (10) having a pressure sensor (20) which is adapted to be selectively and operatively positioned within a fuel fill vent hose (22) in a non-on-board refueling vapor recovery system and which detects fuel vapor leaks. The pressure sensor (20) includes a generally rectangular housing portion (44) and a terminal portion (42) which communicatively connects the sensor (20) to a controller. A conventional pressure sensing device (56) is contained within housing portion (44). Sensor (20) further includes two opposed, generally hollow vent line connection ends or portions (46), (48) which connect to vent hose (22). Portions (44), (46), and (48) cooperatively form a generally cylindrical pressure sensing passageway (54) in which pressure sensing device (56) resides, thereby allowing the device (56) to accurately sense and measure the value or amount of fuel vapor pressure traveling through passageway (54).
