Go Fuel In-Tank Retrofit Kit

NOTE: This In-Tank Fuel Pump Kit can be used with any EFI or carbureted

application when the proper bypass regulator is used.

Warning: Caution must be observed when

installing any product involving fuel system parts

or gas tank modifications. Work in a well-

ventilated area with an approved fire extinguisher

readily available. Eye protection and other safety

apparel should be worn to protect against debris

and sprayed gasoline. We recommend having

this installation performed by an experienced,

qualified, and FiTech approved automotive

technician. The finished installation must be

thoroughly checked for any fuel system leaks.

The fuel system is under pressure, so be sure to

relieve the pressure before opening the fuel

system. All safety precautions must be observed

when working with fuel.

Caution: Before starting this installation be sure

the negative terminal is disconnected from the

battery, you have proper eye protection, a fire

extinguisher handy, and that you are working with

a clean and free of combustible fumes fuel tank.

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 flammable. Drilling and grinding can

be a potential ignition source. Smoking is

prohibited and extinguish any open flames. Start

with a new fuel tank or have the fuel tank

professionally cleaned for the safest install.

Failure to comply with these warnings could result

in injury or death.

Recommended Tools

•Slow Speed Drill Motor

•4 1/4"DiameterHole Saw

•Round fine file

•Shop Vacuum

•3/16 Allen Wrench

•Screwdriver: Flat Head

•Hack Saw

•3/8 and 5/16 Wrench

•9/32"Diameter Drill Bit

IMPORTANT Special Instructions

•For extended fuel pump life never let car go below 1/8th tank of gas.

•If using hard fuel lines make sure to use high pressure EFI rated lines and flared

fittings.

•Make sure that you remove ALL low-pressure flex joints on factory fuel lines and

replace them with EFI rated fuel hose and use proper flared connections and

clamps. Be careful not to mix 45° SAE fitting and 37° AN fittings, they look similar

but will not work together. 45° SAE fittings usually come from a hardware store or

auto parts store while 37° AN fittings are the ones supplied by FiTech and most

speed shops.

• Use at least a 3/8" ID hose for a return line.

•FiTech does not recommend aluminum fuel lines EVER! Use EFI high pressure

fuel hose on any plumbing in your system where high pressure is present.

•If using Push-Lok style hose and fittings in your fuel system, make sure all parts

come from the same manufacturer. Mixing brands of hose ends and hose could

cause leaks.

•FiTech's EFI systems are designed for use with unleaded pump gasoline. Leaded

gasoline is not recommended for safe operation.

•Relieve the pressure from within the system before opening the fuel system.

•Very important note: Your fuel tank must have a vent or use a vented cap to

prevent pressure building up inside the tank!

Features

The FiTech Go-Fuel In-Tank Pump Module isdesigned for almost any fuel tank

depending on depth. By mounting the fuel pump in the appropriate position on the

return tube, itcan be installed in tanks ranging from 7to 15 inches in depth. Note that

these instructions and this kit address installation in baffled fuel tanks (Sock Version

#1) as well as stock fuel tanks (Sock Version #2).The system comes with a high flow

fuel pump or pumps.These pump flow 340 LPH which is good for up to 800 HP in

naturally aspirated applications. Properly mount fuel pump with proper fuel tank sock to

ensure clean fuel, extended fuel pump life, and a steady pickup to the pump. If

necessary, replacement parts are available from: www.FiTechEFI.com

Caution: Wear eye protection and ensure tank is free of

combustible fumes!! Have a radiator shop boil out the

tank.

If installing into Fuel Cell with 12 Bolt Flange already drilled

skip to Installing the C-Ring on next page.

Drilling the hole:

1. The In-Tankassembly must be installed into the top side of the fuel tank.

2. Before beginning to cut the 4 1/4"diameter hole, determine a location to drill the

hole in a central position on the fuel tank. Use the C-ring to help choose the

location. Try tofind a flat area of the tank. If this isnot possible due to ribs in the

tank, the supplied thick foam gasket will be required for the installation.

3. In selecting your hole location, be

sure to avoid the stock fuel level

sending unit assembly and stock

fuel pump pickup.

4. With the C-ring in position, mark a

spot in the center of the ring.

Using a scribe, you can scribe a

circle around the inside of the C-

ring and then measure from the

scribed line to find the center

point.

5. Now, you are ready to begin your

cut, drill a 1⁄4" pilot hole in the

center of the X spot. (Figure 1)

6. Then using a slow speed drill with

a 4 1/4"hole saw, cut a hole in the

tank. (Figure 2) Caution edges will

be sharp once hole iscut through

the fuel tank.

7. Remove the cut piece and use a

file to deburr the sharp edges.

Figure 2

Installing C Ring

1. Place and center C-Ring on top

of recently cut hole. Use the C-

ring as a template, to mark the

(12) 9/32" holes in the tank. Set

C-ring aside, drill and deburr the

holes. (Figure 3)

2. Thoroughly clean the tank to

remove all ofthe metal chips and

debris inside and outside of the

tank. Prior to final installation, it is

important that the inside of the

tank istotally clean.

3. Screw the 2 threaded rods into

two holes opposite of each other

on the C-ring. Slide the C-Ring

into the 4 1/2" diameter hole

(Figure 4 & 5) inserting the

threaded rods back up through

the drilled holes. Then install the

Foam Gasket

(Item 3) as shown in Figure 6.

See Figure 20 on page 9 for

proper assembly ofthese parts.

5. Snap the Filter Sock (Item #14) onto the end of the Fuel Pump.

Figure 3

Figure 4

Figure 6

Figure 5

6. Measure depth of tank and

determine where pump needs to

be positioned vertically (Figure 7.)

Once you have determined proper

pump location so that filter sock

will be within an 1/8" of the bottom

of the tank when installed, cut the

opaque hose and metal support

rod to the desired length (Figure 8

& 9.) Using a heat gun, heat the

end of the hose that will go onto

the fuel pump (Figure 14). Push

the heated hose onto the outlet

nipple of the pump. Note: Be sure

to push straight and evenly. Do

not force as pump nipple can

break. If hose is not fully on pump

nipple, reheat hose prior to

pushing further.(Figure 17)

Secure with a hose clamp. (Item

10)

7. Determine the correct length of

the black return hose. It should be

long enough to be about 1/4" off

the bottom of the tank. Cut hose

at a 45-degree angle.

8. Locate the pump against the

support bracket and secure into

position with two Tie Wraps (Items

15). Make sure Tie Wraps are

pulled tight. See Figure 16. Plug

the electrical connector onto the

fuel pump.

9. Insert Pump Assembly into tank. Lower down

over the threaded rods and use 1/4-20 nuts to hold

module into place.(Figure 10)

10. Install allen bolts with sealing washers into the

open 10 holes. Remove the two threaded rods and

install the last two allen bolts. Tighten securely

using a crisscross pattern to tighten module down

evenly.
