FiTech 40005 Installation Instructions Manual
Inline Frame Mount Fuel Pump Kit (#40005)
Installation Instructions
The FiTech Inline Fuel Pump Fuel Delivery Kit is an inexpensive solution for a fuel delivery system. This style
of fuel delivery when used with a FiTech Go System EFI
does require a return line to the fuel
tank. All necessary hose, hose ends,
and fittings are supplied.
The most critical aspect of this
installation is making sure that the
fuel pump and the filter between the
pump and the tank are mounted as
low as possible. Ideally the pump
should be at least as low as the bottom of the tank. These pumps are
engineered to push fuel, not draw it
in from the tank. Even though the
pickup from the tank may be higher
than the pump, once this line is primed it will function
satisfactorily. Note that mounting the pump too high will
contribute to premature failure. Please read the complete
instruction manual so you have a
good oversight of the installation.
The Inline Fuel Pump Fuel Delivery Kit is capable of providing
enough fuel for engines producing
up to 600 HP when used with either the 4-injector FiTech EFI systems or also when used with the
8-injector units. Note that these
systems are still suitable to be
used on engines that are making
as little as 200 HP.

The Inline Fuel Pump Kit can be used in conjunction with any EFI system. These
instructions are focused on pairing it with a FiTech EFI System but the instructions
can easily be adapted to suit any other EFI system that is being utilized.

Note that the FiTech EFI Throttle Body has
three fuel inlet ports that can be used. Two
additional ports are marked "A" below. Any
unused port should have a plug installed.

The installation of fuel related components should be
done in a well ventilated area free of any possible fire hazards. 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 blockoff 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 entering 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 return 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 either 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
