Query: Fuel pressure Guage

Gauge was and still is 1.5 lbs off (low), checking with manual pressure pump, and two other gauges. But allowing for that diffence, it will be okay. At five psi, it reads 3.5 psi, and reads 1.5 psi low all across the scale. For the low price paid for it, along with the cost of return shipping, returning it would be a waste. I will be using it only ocassionally, to check fuel pressure temporarily, so it isn't like I will have it working all the time.
