Since running out of fuel is usually not a pleasant experience and can be a big inconvenience, especially on diesels, we recommend keeping the fuel level above the 1/4 mark on your gauge. The gauge registers approximately how much fuel is in the tank, but due to the design of fuel pickup tubes, all fuel in the tank may not be able to be used. Sometimes on diesel models, when low on fuel, foaming may occur in the tank and cause air to get in the lines. This may cause erratic engine performance which would alert you to a low fuel situation. AGAIN: We recommend keeping the fuel level above the 1/4 mark. (For use when changing fuel filters) 3116 CAT (U240) Fuel Filter Replacement: Engine should not require priming for normal fuel filter replacement.

Both the primary (Racor 'frame mounted') and the secondary should be filled with fresh, clean fuel before installation. After new filters are installed, start engine, hold RPM at approximately 1200, for 1 to 2 minutes to clear any entrapped air. Primary fuel filter is located on the frame on the driver's side of engine. The secondary fuel filter is located on the engine at rear of coach. Priming Engine: In the event the engine has run out of fuel, priming will be necessary, due to air in filters, lines, lift pump, injector pump, injector lines, and injectors. The following procedure should be followed: 1. Add a minimum of 10 - 20 gallons of fuel to tank.

Fill fuel filters. The pump is located on the base of the secondary filter at rear of coach. The pump will be hard to pump at first and then get softer. This is a sign that air is in the system. Continue pumping until it gets hard again. If engine doesn't start in 10-15 seconds, loosen all six fuel injector line nuts, one to two turns. Crank engine for 30 seconds to expel air from pump and lines.

Tighten the six injector line nuts previously loosened. Start engine. National priority list. If engine runs 'rough' or 'clacks' (louder than normal), loosen injector nuts, one at a time, with engine running, until air is expelled from lines.

Never operate starter for longer than 30 seconds. Allow 2-5 minutes cool down between starter activations of 30 seconds. Cummins C8.3 (U280/U295C) 1. Change filters (making sure to fill new filters with diesel ). Push knob on, pump in and out. The knob will be hard to pump at first and then get softer.

This is a sign that air is in the system. Continue pumping until it gets hard again. Crank engine and 'rev' to about 1500 RPM.

If engine does not start after 5-10 seconds, pump again, then crank engine. Cat 3176 (U300) Use same procedure as Cummins C8.3 except: 1. Pump unlocks and locks by pushing in on knob and turning it 1/4 turn before pumping. Change primary filter first.(located next to pump). Crank engine with throttle all the way to the floor and let back off to 1500 RPM when engine starts and hold for 1-2 minutes. Change secondary filter (located next to engine). Repeat pumping and cranking procedures.

Cat 3176 or Cummins M11 (U320C) 1. Change filters (It is not necessary to fill new filters with diesel ). Press air purge button on Winn control panel at rear of coach 3. Wait 80 seconds (until the unit shuts off). The engine can be restarted.

SELF-PRIMING CENTRIFUGAL PUMPS RECORDING MODEL AND SERIAL NUMBERS Please record the pump model and serial number in the spaces provided below.

Your Gorman-Rupp distributor needs this information when you require parts or service. Pump Model: Serial Number: The following are used to alert personnel to procedures which require special attention, to those which.

This information applies to G-R Self- Priming Centrifugal pumps. These pumps are available as basic, pedestal- mounted models or as close-coupled models driven by either an electric mo- tor, gasoline or diesel engine.

Refer to the manual accompanying the power source before attempting to begin oper- ation. to a boil, build pressure, and cause the pump casing to rupture or explode. Do not remove plates, covers, gauges, pipe plugs, or fittings from an over- heated pump. Vapor pressure within the pump can cause parts being disen- gaged to be ejected with great force. Al- low the pump to cool before servicing. Fuel used by internal combustion en- gines presents an extreme explosion and fire hazard. Make certain that all fuel lines are securely connected and free of leaks.

Never refuel a hot or run- ning engine. Avoid overfilling the fuel tank.

Always use the correct type of fuel. Never tamper with the engine governor to gain more power. INSTALLATION - SECTION B Review all SAFETY information in Section A. Since pump installations are seldom identical, this section offers only general recommendations and practices required to inspect, position, and ar- range the pump and piping. Most of the information pertains to a standard static lift application where the pump is positioned above the free level of liquid to be pumped. List manual to be sure your overall application al- lows the pump to operate within the safe operation range. PAGE B - 2 SELF-PRIMING CENTRIFUGAL PUMPS Materials Either pipe or hose maybe used for suction and discharge lines; however, the materials must be compatible with the liquid being pumped.

slopes down to the pump at any point along the suction run, air pockets will be created. Fittings Suction lines should be the same size as the pump inlet. If reducers are used in suction lines, they should be the eccentric type, and should be in- stalled with the flat part of the reducers uppermost to avoid creating air pockets.

In low discharge head applications (less than 30 feet or 9 meters), it is recommended that the by- pass line be run back to the wet well, and located 6 inches below the water level or cut-off point of the low level pump. Valve in Open Position During the priming cycle, air from the pump casing flows through the bypass line, and passes through the Air Release Valve to the wet well (Figure 2). Valve in Closed Position When the pump is fully primed, pressure resulting from flow against the valve diaphragm com- presses the spring and closes the valve (Figure 3).

Adjusting the alignment in one direction may alter the alignment in another direc- tion. Check each procedure after altering alignment.

Coupled Drives When using couplings, the axis of the power source must be aligned to the axis of the pump shaft in both the horizontal and vertical planes. Select pulleys that will match the proper speed ra- tio; overspeeding the pump may damage both pump and power source. Do not operate the pump without the guard in place over the rotating parts exposed rotating parts can catch cloth- ing, fingers, or tools, causing severe in- jury to personnel. SELF-PRIMING CENTRIFUGAL PUMPS OPERATION - SECTION C Review all SAFETY information in Section A. Follow the instructions on all tags, labels and de- cals attached to the pump.

If overheating does occur, stop the pump immedi- ately and allow it to cool before servicing it. Con- tinued operation should bring the temperatures down to normal levels.
