Congratulations on your purchase of your new Sniper EFI Conversion Fuel Tank.
Let me take you step by step through the installation process now.
The first thing you find when you open the box is a fuel tank, specific to your application.
We also include a set of straps, fuel level sending unit, fuel level float, mounting gaskets
and hardware for the pump and sending unit, complete detailed instructions, the fuel pump
module hanger, an in-tank fuel pump, filter sock, a roll over valve, and clamp and zip
ties to mount the pump.
The first step in installation is to measure the depth of your tank.
Using the tape measure, measure the total depth of the fuel tank at the larger, 2 and
a quarter inch opening.
Take your reading at the top of the fuel tank surface.
This tank has a depth of 6 and a quarter inches, write this measurement down.
Next you need to get a measurement of the pump height with the filter sock installed.
Do this by firmly pressing down on the pump, in to the filter sock, then take your tape
measure, and from a flat surface, measure to the top of the pump or the base of the
nipple, we're right at 4 and a quarter inches.
That will be your pump height.
Now subtract the pump height, which was 4 and a quarter inches from the total depth
of your fuel tank, 6 and a quarter inches, in our case we come up with a 2 inch measurement.
This 2 inches is measured from the base of the fuel sending unit onto the fuel sending
tube, place your mark at 2 inches, that's where we're going to make our cut.
Make a clean cut using a pair of sharp hose cutters at the mark that you placed on the
pick up tube.
Using the heat gun will help you soften up the material so you can slide the fuel pump
on easier.
Install the included hose clamp, remove the protective cap from the fuel pump and firmly
press the pump onto the supply line until it is fully seated.
Rotate the fuel pump now until it makes contact with your return line, make a mark at the
base of the fuel pump on your return line, and cut a 45 degree angle on the return line
itself.
Now you can tighten the hose clamp on the supply tube and zip tie the return tube directly
to the fuel pump housing itself.
Go ahead and cut the excess off now.
Don't forget to connect the power wires to your fuel pump before installation.
Before you install your fuel pump module, make sure that the filter sock is indexed
with any recesses that may be in the bottom of your fuel tank, make sure to install the
rubber gasket.
Now your ready to install the complete fuel module into the fuel tank.
You'll have to line up the pump hanger with the gasket and the holes in the tank.
Now go ahead and mount the fuel pump module to the fuel tank using the supplied hardware.
Your fuel pump module installation is now complete.
Now lets move on to installing our fuel level sending unit.
When using a fuel tank with depths between 6 inches and 15 and a half inches, the lower
bracket is not needed, you'll have to remove the assembly, remove the lower bracket, and
reinstall onto the upper bracket.
Begin by removing the 2 Phillips head screws that are holding the housing onto the lower
mounting bracket.
Retain these for later, you'll need them to remount it.
Remove the other 2 Phillips screw heads that hold the 2 mounting brackets together.
Slide the lower bracket off, reinstall the housing onto the upper bracket, and reinstall
the mounting screws but do not tighten.
Now using the 6 and a quarter inch measurement that we determined earlier by measuring the
depth of the tank, divide that by 2 and you come up with 3 and an eighth inches, add another
eighth of an inch for the gasket thickness, and measure form the base of the fuel sending
unit to the center line of the pivot to 3 and a quarter inches.
Secure it and tighten your screw, and you've established your height.
It may be necessary to remove a portion of the bracket below if it interferes with the
bottom of your tank.
You have to remove the temporary shaft installed in the assembly and install the new float
arm assembly.
Lightly tighten the float arm retaining screw for now.
Using the adjuster screw, slide the shaft up and down until your float level is approximately
one eighth of an inch below the tank level.
Once you've gotten your correct height, make sure it swings through the motion completely,
and mark the excess rod to show where you need to make your cut.
Now go ahead and install the rubber gasket and install the fuel level sender into your
fuel tank.
Line up the holes in your tank with your gasket and sending unit.
Now install the included hardware and tighten, and your complete.
Now that we've got the fuel pump and the fuel level sending unit installed, all you need
to do now is install the correct fittings that match up to your fuel supply and fuel
return lines on your car.
You also need to connect the wires for your fuel sending unit as well as the positive
and negative power for your fuel pump module.
If your kit came with a roll over valve like ours did, you'll need to connect it to the
tank vent and the fuel pump module vent using a length of hose and a T connector.
Remember the rollover valve needs to be higher than the fuel filler level.
All that's left now to do is install our new tank straps as well as the coupler for our
filler neck and your ready to install.
Pay special attention as you raise the tank into position that you don't pinch any of
your wires or collapse the vent hose as your raising it up.
Finish by tightening the tank straps to the manufactures recommended torque specs.
Your installation of the Sniper conversion fuel tank is now complete.
