Installation:

Tools needed:

1/4” or 3/8” drive ratchet

Different length extensions

8mm socket / 10mm socket / 12mm socket

Needle nose pliers (small and large)

Various size flat head screwdrivers

SAE Quick Disconnect Fuel Line Removal Tool (not pictured)

***WARNING***

6th Element Engineering recommends this fuel line be installed by a seasoned mechanic or professional

automotive garage with relevant experience or auto dealership. Dealing with fuel can be dangerous,

especially if a leak occurs when the car is driving. If you happen to smell any fuel while driving or the

engine sputters and you see smoke, cut the power immediately and navigate the vehicle to a safe place.

Installing the included fittings properly will result in a leak free installation, and using items like ties and

clamps to keep the line in place will make it more secure.


1. Remove the fuel pump fuse from the fuse box. This fuse is labeled on the inside of the engine

bay fuse box cover. After it is removed, start the engine and let it idle until stalling. This

removes the majority of the fuel from the lines.

2. Raise the front of the car and the back of the car as high as possible by using either ramps or a

jack with jack stands. Consult your vehicle instruction manual on safe jack locations.

3. Remove the positive terminal from the battery using a 10mm socket.


4. Remove the battery tie-down bracket using a 12mm socket.

5. Remove the battery from the car and then remove the positive terminal wires from the battery

tray. 10mm socket for the bolt and use a small flathead to pop out the wire tabs.


6. Unplug the ECU and remove the ECU from the car. Pull up on the plastic handles to disconnect

and use 10mm socket for the bolts.

7. Remove the battery tray. There are 4 bolts. Use the 12mm socket.


8. Remove the engine cover by pulling upward to pop it off the tabs. Then take out your current

intake system.

9. Using a small flat head screwdriver, remove the plastic clip cover to the High Pressure Fuel

Pump Line.


10. Get some rags and get them under the stock fuel line as shown below. Using a small pair of

pliers or the Quick Disconnect removal tool, push the plastic retaining clip towards the driver

side to disconnect the fuel line. Be aware some gas will come out of this line. Be prepared to

soak it up with rags.


11. Below is the inlet of the High Pressure Fuel Pump. We are going to install one of the SAE Female

Fittings from your kit.

12. Unscrew the threaded cap from the fitting.

Threaded cap goes in

this section, see next

step.

Lube end with assembly

lube or fresh oil. Just a

drop or two.


13. After removing the threaded cap, install it on the inlet of the High Pressure Fuel Pump as shown.

Then slide the main fitting on to the pump and screw the two pieces together,

14. Finished install with look like this after you tighten the cap and fitting together.


15. Remove the Fuel line cover tray from the bottom of the body of the car. There are 6 or 7 nuts

holding on to the car. Use the 10mm socket.

16. Next, remove the lower rear seat. Kia Forte is referenced. Veloster will be similar. Start by

folding the rear seat forward and removing the bolt holding the lower rear seat. Use the

shortest 12mm socket or wrench you have.


17. After the two bolts are removed, get in the back of the car and pull up on the rear seat. It

should pop out.


18. After pulling the lower seat out, look for the Fuel Pump access plate. You’ll see some wiring

going through it as shown below. You’ll need something sharp to break the gasket sticking it to

the body. We used a thin flathead driver.


19. Once the sticky rubber gasket is a little loose, pry it upward.

20. You should see something like this below.


21. Remove the fuel line from the tank. Pry the sides of the orange clip outwards, then up to

remove the orange clip. Then insert some rags under the line as shown.

22. To remove the line, slowly pull towards the passenger side. Be warned, some gas will come out.

Be ready to clean with rags.


23. Now that the line is disconnected at both ends, remove it from its many mounting clips

attaching it to the car. There are two under the body just in front of the tank. You can reach

them through the hole you have been working in.

24. Follow the line out the driver side and down in front of the tank. The line is the innermost line

towards the middle of the car.

Clips are under the

sheet metal here. Have

fun!


25. Going along the line as you work your way to the front of the car, remove it from the clips

holding to the car. You’ll come to this small plastic cover that will be removed by popping it off

its tabs.

26. Next, go back into the engine bay and unclip the brackets holding the stock fuel line to the

engine.


27. There is another line that pairs with the stock fuel line. This will be removed but put back later.

Using the pliers, disconnect this line as shown.

28. After the clips for the lines in the bay have been removed and lines disconnected you should

have something like this.


29. The last thing stopping you is this bracket holding the two lines to the firewall. Use the 10mm

socket to remove the single bolt. It is a real pain to get but manageable.

30. Once this bracket is gone, you can pull the lines out. Watch out for gas!


31. Here are the two lines removed together. Once you separate the OEM Fuel line from the other,

go ahead and re-run the 2nd line back so you don’t have to mess with it later.

32. Using the same procedure on the fuel pump, install the female SAE fitting on to the tank outlet.


33. Starting with the 180 degree end on your new line, snake it up over the fuel tank from the

bottom of the car.

34. Now it’s time to remove the low pressure fuel pump assembly. Start by removing the 8 bolts

holding it to the tank with the 8mm socket or Philips screwdriver.

35. Grab the plastic and slowly pull upwards. See the next 3 pictures. Be careful of the Fuel Level

buoy and lever (3rd pic).


36. Stand the pump assembly up as shown. We have to dis-assemble it.

37. Push the top portion down. You will see a small C-Clip attached to the rod shown. Remove that

C-Clip with pliers.


38. Before you slide the top portion away from the bottom part, unplug the pump wiring from the

top piece.

39. Looking inside the bottom part, you will see a black plastic hose that needs to be undone to

separate the bottom and top parts of the assembly. You’ll need a long skinny screwdriver to get

these tabs.


40. Now you can slide the top part up and off the bottom part as shown.

41. There are 3 clips that hold the pump portion in the bottom part. Pry those up to remove as

shown in the next two pictures.


42. Turn the filter housing upside down on a flat surface as shown. Now we pop off the fuel filter

sock. There are a couple tabs for this.


43. Now you can slide the OEM pump out of the housing. It might need some pressure from the

other side.

44. Take this o-ring off the stock pump and replace it with the 2 new o-rings in your kit,


45. Put the new pump in just like you removed the old one. Make sure you can easily install the

electrical plug!

46. Now, put everything back together. Then it’s time to finish installing the Fuel Line!

47. Find that 180 degree fitting and screw it on to the SAE fitting. This is where you use the 11/16”

and 5/8” wrenches. You don’t have to turn too tight now, as the –AN fittings will seal fairly

easily.


48. Work your way to the front of the car, keeping the line hugged up against the body. You can

even squeeze it into some of the body clips. See next 3 pictures.


49. Snake the 90 degree end up into the bay and attach it to the SAE fitting at the pump. There

should be a little slack at this end of the line. You can arc it through the bay. Make sure to get

this end tight and secure. Once you have reached this step, use the supplied zip ties to secure

the line. Use more if you want to! The more the better!


50. Get your rags ready at the line connections. Plug your electrical connectors back up and put

fuses and the battery back in. It’s time to check for leaks.

51. First we must prime the fuel line. Do this by pressing the Engine Start button twice to get to the

“ACC” display on the button. You will hear the electronics fire up and a humming sound. This is

the priming of the fuel system. After you hear this noise, wait a few seconds until it stops, then

press the button again to turn it all off. Repeat this process 5 times, then start the car.

52. Once the car starts, it may run fine or it may stumble and hesitate for about a minute. Check for

leaks if running fine, or if it’s stumbling, wait about 10 seconds and turn the engine off. Start it

again and it should idle smoothly. This should only take 2 or 3 times to get a good idle. While

this is going on, check for leaks. If you don’t see any leaks, you can re-install all of your parts.

53. If you have an OBD-II reader, check for any pending codes that might come up. This is normal

when getting fuel through an empty line. Clear those codes once you’re up and running and

you’re good to go! Enjoy your new fuel line that won’t give you any hesitation issues like stock!
