Hello, my name is***** you for allowing me to assist you today.
How long was the engine siting?
How old is the fuel?
Customer: replied 1 year ago.
I just bought the motor, but it has been sitting for at least a year. The gas is also one year, it was about 2 gallons in the tank. To make it better i filled it uo with 2 gallons of new gas.
Expert:  Charles replied 1 year ago.
Can you test the running fuel pressure on the engine. It should read over 30 PSI when the engine is running.
Customer: replied 1 year ago.
I guess I can if I buy a meter and install it on the hose. Is that the first thing you want me to test?
Expert:  Charles replied 1 year ago.
With the motor sitting for as long as it did. I need to know of the fuel pressure is correct before going further.

How do i do that the easiest way?
Expert:  Charles replied 1 year ago.
There is a fitting on the fuel pump that looks like a tire valve. Screw a gauge onto that, and then start the engine. You will then see the fuel pressure.
