GASBOY Series 70 & 1820

Pump delivers product but won't register.

Is main totalizer recording? If yes, problem is in register assembly. Check to be sure the lever on the side of the register is returning back to the record position.

If the main totalizer is not working, the problem is a broken or jammed measuring chamber.

Pump delivery is slow.

✓Check for dirty strainer.

✓If pump has a filter, change filter.

✓An automatic nozzle will reduce flow rate about 25%. Check flow rate without nozzle or with standard nozzle. A farm type automatic nozzle (such as Husky 1GS swivel) provides the best flow.

✓Check for supply line restriction by testing the pump with a vacuum gauge. If vacuum is abnormally high, there is a restriction.

Pump loses prime.

✓Inspect check valve poppet and seat for clean mating surfaces.

✓If, after a period of non-use, a pump delivers product initially, followed by air and then full flow, there is an air leak in the suction line.

✓Install pressure gauge between hose and nozzle. Operate pump at full flow. Snap nozzle closed and turn off pump. If pressure falls to zero rapidly, replace check valve and clean and inspect valve seat.

Inaccurate delivery.

✓Calibrate the meter (See Section 4).

A clock-fast error (more on the register than is delivered) in excess of 2 1/2% is due to air in the suction line or vaporization of gasoline in the pump. Check pump for loss of prime and suction line for air leak.

A clock-slow condition may result from: any slowing of the register or measuring chamber due to excessive friction resistance or mechanical failure; inadvertent bypassing of the measuring chamber. Check register for zero setback; check reset lever return to top of slot in meter cover after setback; check for "hang-up" of number wheels in register or gears not meshing.

Pump delivers product when not turned on.

In aboveground storage tank, if fluid level is higher than pump, positive head pressure may force product through pump. Install a pressure regulating valve or a solenoid valve in the supply line to the pump.

Check for defective vacuum breaker.

Vacuum breaker spits product

✓Clean and replace. If problem persists, install return line kit.
