Inline Frame Mount Fuel Pump Kit (#40005)

Installation Instructions

The FiTech Inline Fuel Pump Fuel Delivery Kit is an in-

expensive 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 bot-

tom 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 De-

livery Kit is capable of providing

enough fuel for engines producing

up to 600 HP when used with ei-

ther the 4-injector FiTech EFI sys-

tems 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.

Fuel Injection

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. ther 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 ine

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

sending unit with a larger fuel line. Vehicles originally

equipped with small block engines typically have 5/16"

lines while big block engines have a 3/8" fuel line. If your

model car was available with both small and big block

engines there should be a 3/8" sending unit available.

Note that some of these sending units have both an outlet

and a return fuel line provision.

If you cannot source a sending unit with a 3/8" fuel

line you will need to have one custom installed in your

tank. This should be accomplished by an experienced

professional who can modify your fuel tank.

Since the line from the tank to the pump is low pres-

sure you can secure the -08 hose to the tank with a sup-

plied hose clamp. The rest of the connections are made

with the supplied push lock hose ends.

Mounting and Plumbing the Fuel Pump and Pre-Filter

Select a location for mounting the pump. Be sure to pro-

vide enough space between the tank and the pump to

allow for the pre-filter. The pump and filter should be

mounted as low as the lowest portion of the fuel tank.

They should also be mounted within three feet of the

tank. This is important to avoid premature pump failure.

This kit includes a billet mounting bracket for the

pump. Using the bracket as a template, mark two mount-

ing holes on the frame (if that's where the pump will be

mounted) and drill 4 MM holes for #10 self tapping metal

screws. Mount the bracket to the frame with the sup-

plied#10 self tapping metal screws.

Note that the pump is directional and must be posi-

tioned with the wire terminals facing the front of the ve-

hicle. Slip the pump into the bracket and clamp it

securely. See Figure 5.

Find a suitable location for the filter positioned be-

tween the tank and the pump. Mount the filter to the

frame using the supplied Adel clamp. Again, drill a 4MM

hole and use a #10 self tapping screw to hold the clamp.

Measure out the necessary lengths of the -08 hose to

run from tank to the filter and from the filter to the pump.

Cut the hose cleanly using a sharp blade. Make sure the

ends are cut square. Install the push lock hose ends by

securing the hose end in a vise, making sure you provide

some protection to avoid damaging the hose end. Do not

clamp too tightly. Push the hose onto the hose end mak-

ing sure it is seated all the way. It will ease installation by

using some WD-40 or similar lubricant.

Connect the hose from the tank to the filter and a sec-

ond hose from the filter to the pump.

Plumbing from the Pump to the EFI

The next step is to determine the lengths of the -06 hose

which will run from the pump to the post-filter and then

a second hose from the filter to the inlet port of the FiTech

EFI system throttle body.

Note that the post-filter can be located anywhere be-

tween the pump and the throttle body. This filter is very

light and can be supported by the fuel hose. No mounting

clamp is required but you will need to provide some type

of support for the fuel line at several points between the

pump and the engine compartment. It can be tie-wrapped

or held in place with small Adel clamps. (Not supplied)

The FiTech EFI Throttle Body has three inlet ports and

one outlet port. The outlet port is marked "Return." Select

one of the three inlet ports and install a supplied -06 AN

inlet fitting. The return port requires a special fitting

which is already installed in the throttle body. Install the

supplied plugs in the two unused ports. You will have one

plug left over. This is required when using the Fuel Com-

mand Center which is returnless and the return port is

also plugged. See Figure 6.

Connect the -06 fuel hose from the filter to the inlet fit-

ting on the throttle body.

Wiring the Fuel Pump

The FiTech ECU mounted on the throttle body has a small

sub harness that is connected to it. In this sub harness

is a large orange wire. Extend that wire and connect it to

the positive (+) terminal on the fuel pump. Connect one

end of a ground wire to the (-) terminal of the fuel pump

and attach the other end to one of the screws holding the

pump to the frame. Make sure the wire makes contact

with bare metal.

Where is the Fuel Pressure Regulator?

You may wonder why no fuel pressure regulator is used.

That's because the FiTech System throttle body contains

an internal fuel pressure regulator that maintains fuel

pressure into the system at a constant 58 PSI.

Fuel Injection

Note: If you are using this #40005 FiTech Fuel Delivery

Kit with a fuel injection system other than FiTech, you will

need to incorporate a fuel pressure regulator between the

post filter and the inlet port on the throttle body, or fuel

rail if it is a port injection system.

What are the two straps in the Fuel Pump Box?

These are mounting straps supplied by the fuel pump

manufacturer. However FiTech supplies a special billet

aluminum Pump Mounting Clamp. The two straps that

are supplied in the box are not needed and may be dis-

carded.

Completing the installation:

nce the entire installation is completed, turn on the main

ignition switch which will activate the fuel pump. Imme-

diately examine every connection checking for fuel

leaks.If any leaks are detected, turn off the ignition switch

and repair all leaks. It is critical that no fuel leaks exist

which could lead to a fire.
