| 1. A fuel pump test apparatus, comprising:
a pressure measurement portion connectable to the fuel pump to measure pressure of fluid flow from the fuel pump,
a flow measurement portion adjacent the pressure measurement portion and connectable to the fuel pump to measure fluid flow
from the fuel pump,
an electrical diagnostic portion adjacent the flow measurement portion and connectable to the fuel pump and to monitor current
draw and operating voltage of the fuel pump, and
a fault simulation portion adjacent the pressure measurement portion, wherein the fault simulation portion allows a user to
simulate potential fuel system failures to determine the operation of the fuel pump;
wherein said fault simulation portion comprises an adjustable needle valve, said adjustable needle valve being capable of
simulating a flow obstruction of a fuel pump by restricting an output of said fuel pump.
