Do not check for fuel leaks with your hands. Very small leaks can result in a high velocity fuel stream that will be invisible close to the leak. This fuel can penetrate the skin and cause personal injury. Use cardboard or paper to check for fuel leaks.
Do not crank the engine continuously for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking the engine again.

Check the pressure at the fluid sampling valve and record the value. Refer to Illustration 1 for the location of the fluid sampling valve. Compare the recorded value to the minimum pressure value in Table 1. If the recorded value is greater than the minimum value, the fuel system pressure is ok.
