DESCRIPTION: Edelbrock Quiet-Flo Electric Fuel Pumps feature anodized aluminum housings and high quality internal construction, making them  
strong, durable, and quiet. #1790 features a -10 AN inlet/outlet, while #1794 features a -12 AN inlet/outlet. Both pumps are compatible with all  
grades of gasoline and methanol type fuels. Performance Specifications are listed below.  
CAUTION!  
Installation of this product should be performed by persons knowledgeable in the repair and modification of high pressure automotive fuel systems.  
Do not loosen fuel system connections until relieving fuel pressure as recommended in your automotive service manual. Fuel leakage  
will occur when loosening fuel system connections, eliminate potential fire hazards before loosening any fuel system connections.

INSTALLATION:  
NOTE: The use of a pre-filter (60 micron maximum) is needed before the fuel pump, and a 10 to 30 micron (maximum) is needed after the fuel  
pump. If a pre-filter is not used, early fuel pump failure can/will occur. See Figure 1.  
IMPORTANT: When choosing pump location, make sure to mount the fuel pump at or below the level of the bottom of the fuel tank. This will  
ensure that the fuel pump will have a head of fuel pressure on the inlet side to aid in priming the fuel pump. Damage to the pump will occur if  
the pump is mounted incorrectly. See Figure 1.  
1. With the ignition “off” and engine cool, relieve the fuel system pressure.  
2. Disconnect the existing fuel pump lines. Plug the open fuel lines to prevent foreign matter from entering the fuel system. Remove  
existing fuel pump.  
3. Determine the new fuel pump mounting location. Remember, the fuel pump must be mounted at or below the bottom of the fuel  
tank.  
4. Replace existing fuel lines as necessary for proper fitment. Use existing bracket holes, if possible. Otherwise, for #1790, mark and  
drill mounting bracket holes using the brackets as a template. On 1794 fuel pumps, the mounting brackets are integral to the body  
of the fuel pump. Hold the fuel pump in position and use the mounting holes as your template.  
5. Assemble the bracket and fuel pump (On 1794, bracket assembly is not required).
