Abstract
A method and apparatus for testing of a portion of a fueling and fuel vapor recovery system. The apparatus is adapted to pressure test a fuel delivery hoses, break-away, and nozzle combination. The fueling and fuel vapor recovery system can be tested in parts in order to determine whether a particular portion has failed.
Claims12
An apparatus adapted for the pressure testing of a fuel delivery and vapor recovery system, said apparatus comprising:
- a hand pump portion, said hand pump portion comprising a check valve;
- a coupling, said coupling fluidically coupled to the downstream end of said check valve, said coupling adapted to directly couple said hand pump portion to vapor recovery capable fueling components, said coupling rigidly coupled to said hand pump portion;
- and
- a pressure gauge, said pressure gauge mounted to said hand pump portion, said pressure gauge adapted to measure the pressure within said apparatus downstream of said check valve.
A method for the testing of a fuel delivery and vapor recovery system, said method comprising:
- removing a short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination from a gasoline dispenser at the dispenser-short dispensing hose interface;
- attaching a manual pressure testing apparatus to the short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination at the dispenser-short dispensing hose interface;
- and
- hand pumping said testing apparatus to create a pressure in said short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination.
A method for the testing of a fuel delivery and vapor recovery system, said method comprising:
- removing a short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination from a gasoline dispenser at the dispenser-short dispensing hose interface;
- attaching a manual pressure testing apparatus to the short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination at the dispenser-short dispensing hose interface;
- hand pumping said testing apparatus to create a first pressure in said short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination;
- measuring said first pressure;
- monitoring said first pressure for a defined length of time;
- disconnecting said fuel hose breakaway from the short dispensing hose, fuel hose breakaway, fuel hose, and nozzle combination;
- attaching a manual pressure testing apparatus to a first end of said fuel hose breakaway;
- attaching a plug to the second end of said fuel hose breakaway;
- hand pumping said testing apparatus to create a second pressure in said fuel hose breakaway;
- and
- measuring said second pressure.
An apparatus adapted for the pressure testing of a fuel delivery and vapor recovery system, said apparatus comprising:
- a hand pump portion;
- a coupling, said coupling fluidically coupled to said hand pump portion, said coupling rigidly coupled to said hand pump portion;
- said coupling comprising:
- a first end, said first end rigidly coupled to said hand pump portion;
- and
- a second end, said second end adapted to couple to a vapor recovery capable fuel hose;
- and
- a pressure gauge, said pressure gauge mounted to said hand pump portion.
