Installation of the Fuel Delivery System
The installation of fuel related components should be
done in a well ventilated area free of any possible fire haz-
ards. Gasoline fumes are toxic and highly inflammable.
1. Disconnect the negative (-) terminal of the battery.
2. Release the pressure in the fuel system by removing
the gas cap.
3. Remove the stock fuel lines from the factory fuel pump
and remove the pump from the engine. Clean off the
block's mounting surface and install a fuel pump block-
off plate (not supplied). Make sure you acquire a block
off plate for your specific engine.
4. If a low pressure electric pump is being used you may
already have a pump block-off plate. Remove all of the
electric pump components.
5. Disconnect the factory hard line (or hose) from the
tank's sending unit assembly. Note that the factory hard
lines can be completely removed if not used for the return
line. If not removing or using as a return line, cap the
ends of the factory hard line to avoid contamination en-
tering the tank.
6. For proper operation of the EFI system, a return line
provision must be installed onto the fuel tank sending
unit. You have several options for doing this.
Note: Some vehicles already have a return line which
may be used. Other methods require welding on the tank.
It is recommended that any welding be performed by a
qualified professional. Here are your various options:
A. Using the supplied rubber -06 hose:
A1. Weld in a 5/16" hard line inlet onto the
sending unit cover plate (see Figure 2), or...
A2. Install a -06 AN bulkhead fitting onto the
sending unit cover plate (see Figure 3), or...
A3. Install a Moroso #65385 Return Kit in
your filler neck. See Figure 4.
B. Use the vehicle's existing fuel hard line as the fuel re-
turn line with modification to the sending unit and pickup.
C. Use the vehicle's existing fuel return line (if equipped)
as the fuel return line.
Note: Regardless of which of the above systems you use
for a return line, it is important to locate the in-tank return
line as far as possible from the fuel pickup line. This will
avoid drawing aerated return fuel into the inlet line fuel
pickup.
Fuel Inlet Line
Fitech recommends using a -08 inlet line from the tank
to the pump. From the pump to the engine a -06 line is
suitable. The -08 line is necessary to avoid fuel starvation
to the pump which can damage the pump. The hose and
hose ends supplied in this kit are configured for a -08 line

from the tank to the pump. If you elect to use -06 line
(not recommended) you will not have enough hose ends.
Using a -08 line from the tank may require installing
a larger pickup in the tank. Some stock tanks have a 5/16"
diameter fuel tube. This is too small. The outlet line from
the tank should be a minimum of 3/8" in diameter and
1/2" is better. The -08 supplied fuel hose will work on ei-
ther a 3/8" or 1/2" tube. If your current tank has a 5/16"
fuel line coming from the sending unit, do some online
searching (search "fuel sending units") for a replacement
