I claim: 1. 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. 2. The apparatus of claim 1 wherein said hand pump portion further comprises: a pump cylinder; a pump piston, said pump piston adapted to travel within said pump cylinder; a pump shaft attached on a first end to said pump piston, said pump shaft adapted move said pump piston axially within said pump cylinder; and a pump handle, said pump handle attached on a second end to said pump shaft. 3. The apparatus of claim 2 further comprising a pressure relief valve, said pressure relief valve attached to said hand pump portion, said relief valve adapted to relieve pressure from within a volume downstream from said check valve. 4. The apparatus of claim 2 further comprising a pressure relief valve, said pressure relief valve attached to said hand pump portion, said relief valve adapted to relieve pressure from within a volume upstream from said check valve. 5. 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. 6. The method of claim 5 further comprising: measuring said pressure; and monitoring said pressure for a defined length of time. 7. 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. 8. The method of claim 6 further comprising: disconnecting said nozzle 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 nozzle; hand pumping said testing apparatus to create a pressure in said nozzle; and measuring said pressure. 9. The method of claim 6 further comprising: disconnecting said short dispensing hose 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 short dispensing hose; attaching a plug to the second end of said short dispensing hose; hand pumping said testing apparatus to create a pressure in said short dispensing hose; and measuring said pressure. 10. The method of claim 6 further comprising: disconnecting said fuel hose 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; attaching a plug to the second end of said fuel hose; hand pumping said testing apparatus to create a pressure in said fuel hose; and measuring said pressure. 11. 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. 12. The apparatus of claim 11 wherein said hand pump portion comprises a pump axis, and wherein said coupling further comprises a central axis, wherein said pump axis ans said central axis are substantially coaxial.
