ive never been able to get anywhere near 17 or 19 gallons into my tank, even when I ran it out of gas...Last fill up I had the gas light on and only got 14.91 gallons into it...


Got me.... this is what I've been going by:

Fuel Pump Pressure: (22R) 2.8-4.3 psi; (22R-E) 36-38 psi

Maybe somebody stuck a pickup tank in it?
