Stage II Fuel System Parts List & Instructions

1) Install Pick up Tube. Fuel Pick Up Tube Instructions For Fuel Injected 5.0 Mustangs 86 to 95

A. Drain gas tank. Jack rear of car up and place jack stands on the rear frame rails so that
the rear axle will hang with no load. Drop the tank by removing the bolts at the end of the
straps between the rear axle and the tank. Remove the small screw at filter neck. Use a
jack or have someone help you when lowering the tank to avoid injury. Use caution when
removing the tank, not to tear the rubber seal around the filter neck.

B. Once the tank is down, disconnect the fuel level sending wires located in the middle of
the tank. Then, remove the fuel lines at the tank. (CONTENTS MAY BE UNDER
PRESSURE - TAKE PRECAUTIONS) Once fuel lines are disconnected from the tank,
you can remove the retaining ring that holds the factory pump assembly in. Be careful with
this ring and seal, you will reuse them later.

C. Remove the Pump Assembly and the screen from the tank. Again USE CAUTION
when removing, this is a vital part and needs to be re-used. We suggest a screw driver
between the pump and screen to gently pry off.

D. Prepare the CarTech pick up tube by installing the fittings you are using using Teflon
tape on the threads. Hold pick up tube with a vise grip to install fittings.
(DO NOT over tighten)

E. With fittings installed, take the original pick up screen, clean, and snap onto the Cartech
pick up tube. It will only go on the outlet tube, by simply snapping it to the end. The
groove machined into the boss keeps the screen from coming off. Once it's on, it will not
come off without destroying it. Rotate the screen so that it extends out with the natural
curve of the pick up tube.

F. Check the factory rubber seal ring for tears or cuts. If seal ring looks good, you can
reuse it. If it has tears or shows signs of wear, replace it. After you've decided about the
seal ring, put it back in it's original location. Install the pick up tube by sliding the screen
into the slots on each side of the hole. Rotate the assembly towards the front of the car.
The pick up tube will only fit in the tank the one way as described above.

G. Re-install the retaining ring. Now you need to run your fuel lines to the tank for the
pump and return lines. Once lines are run, attach wires for the fuel level sensor and mount
the fuel tank. We suggest using silicone spray or WD-40 around the filter neck
grommet for easier installation.

H. Hook up your fuel lines to your pump and the rest of your car. It is critical to mount
the pump at the midway point of the tank or lower. If you don't do this it can cause
premature pump failure. We recommend using our pump mounting plate for exact
placement.

2. Remove Stock Filter bracket and cut off the small tab that protrudes from near the stock filter.
Place CarTech filter into the output side of the fuel pump as pictured.

3. Run -10 Steel line from the Fuel Pick Up Tube to inlet side of the fuel pump using -10 Hose ends
at both ends. Run feed lines and return lines along frame rail and secure with supplied adel clamps.

4. Install Fuel Rails
A. Remove factory chrome feed, return lines, and fuel rails. (Contents may be under
pressure, Take Caution) Remove injectors from original rails. Clean and cover to keep dirt
and dust out.

B. Take CarTech Fuel Rails and install desired fittings. Use loctite pst, liquid teflon or
teflon tape. When using teflon tape do not run tape over the hole in the end, as pieces of
teflon can get into an injector and clog it. (See diagrams 1 & 4 on following pages for
proper fitting use. We recommend using diagram 1 with a CarTech fuel pressure
regulator) Do NOT over tighten fittings into fuel rails, it can cause the rails to leak if done
improperly.

C. Take injectors and install them into the CarTech rails by using silicon spray or WD-40.
Be careful not to pinch the injector o-rings and take your time. Once in, rotate clips to the
outside of the rails.

D. Set rails on the intake. The rail that is capped off goes to the front on the driver's side.
Use the spacers provided between the intake and the brackets if needed. (Stock distributor
will need spacers on driver's side only and MSD requires no spacers)

E. Run -8 Braided Line in the back as a crossover. Then run the fuel inlet on passenger
side and -6 return out of the driver's side to the fuel regulator.

F. When cutting braided line - mark it from the middle of the fitting, then wrap duct tape
(or suitable tape) over the hose, center the mark on the hose to the center of the tape. Cut
it with a saw, wheel, band saw or hack saw. De-burr and install into receiver part of the
fitting (red part) and turn counter clock wise until hose is positioned just below the
threads in the receiver fitting. Spray silicone or WD-40 into this hose and fitting. Then
install the other part of the fitting. Be careful not to strip the threads. Tighten until both
parts of the fitting are flush. Some adjustments may be required to ensure all fittings line
up w/ no bind in the hose.

G. When running your fuel line, do not run any lines through the drive shaft tunnel, not do
you want to mount the fuel regulator to the firewall. Fuel lines must be on the outside of
the frame rails and/or frame connectors. ANY deviation from these specific instructions
could cause your vehicle to fail technical inspection or be disquilified from any N.H.R.A.
owned or operated track, or any track following the N.H.R.A rules. For further rules and
regulations on fuel systems, please refer to page 140, section 1:5 of the N.H.R.A.
Rule Book

H. Tighten all of the fittings at all of the joints and prime the fuel system. DO NOT start
your engine! Just prime to check for leaks at the injectors, rail fittings, regulator, and fuel
inlet. To properly set and check pressures, it is recommended that you use a fuel pressure
check gauge at the regulator or an -8 to -8 fitting supplied in the fuel systems. An under
the hood gauge as well as a cowl or inside your car gauge will help in tuning your engine
to it's peak performance. Note: Do NOT run fuel inside the car; An isolator kit will be
needed for cockpit mounted fuel pressure gauges.

I. Once you have checked for leaks, start engine and check again. Periodically check
fittings and hoses for leaks as well.

5. Mount the Regulator.
A. See diagram 4 for fuel rails.

6. Remove the inlet fitting to the rails and bleed the system to remove any debris from the lines.

A. See diagram. The diagram is your instructions.

8. Check the System for leaks and set fuel pressure.
