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).
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
