#135131 This is an overview. Carefully read the instructions that are included with your fuel pump. It's also important to disconnect the battery. Any spark around an open gas tank & fumes inside your car = :death:

After disconnecting the battery, remove the lower part of the rear seat to get to the access cover.

Image
remove the 4 phillips screws holding the cover on.

Image
Disconnect the wiring harnesses.

Image
Remove the clamp on the return fuel line.

Image
Remove the banjo bolt from the fuel line. Notice the order goes Washer - Banjo Bolt - Washer. Don't lose the bottom washer.

Image
After you loosened the banjo bolt, loosen the 6 outer bolts in a criss cross pattern. These hold the top on to the tank. One of mine was really rusty so I had to use a slightly smaller socket and tap it on with a hammer.

Image
Have some towels handy when you pull the pump out.

Image
Old pump is on the left, Walbro 255 LPH and install kit is on the right.
You reuse some of the oem parts for the install.

Image
This clip is a double clip. You need to remove the green one first to remove the black one.

Image
I unscrewed the ground screw and it broke off. I wanted to move it out of the way but it turns out it would have been fine if I left it alone. So don't do what I did!

Image
I removed the green clip with a small flat head, then the black plug.

Image
Pull the rubber insulator out of the bottom clip. It's a tight fit.

Image
The only thing left is the rubber hose.

Image
I removed the clamp with pliers and the pump is now separate from the assembly.

Image
The rubber isolator is reused on the new installation. With a pair of needle nose pliers, I removed the metal lock thingy?

Image
Stick the new isolator on the new pickup bag thingy.

Image
And that will go on the new pump just like it was on the old pump. There's a new lock in the install kit.

Image

Image

Image
It went on easy with a small socket, applying even pressure to all sides.

Image
Measure twice and cut the new fuel hose once.

Image
Put the clamps on loosely.

Image
Put the pump on. Get it snug in the insulator and tighten the clamps.

Image
Plug in the harness & clip

Image
All done!

Image
Now get back to the car and install it in the reverse order that you removed the stock one.

Image
One thing I had to change was the position of the screw on the clamp to make the pump go in. I rotated the clamp on the hose 180° and it went in the tank fine.

Once everything is back together, connect the battery and turn your key in the accessory position a few times to get pressure back in your line and you should hear the pump whine. The 255 LPH actually makes more of a growl compared to the stock pump whine :twisted:

If you are observant, you may have noticed that my new pump is upside down with the plug on the bottom and hose on top. I believe I was shipped an EF pump, but with an EG install kit. I found a way to make it work, it was just a little tighter fitting the hose and harness. An EG pump should have been exactly the same.

#135556 Nice write-up Teal, good to see all the steps laid out. As you know, there's a good chance I'll be doing mine soon so this will definitely be a help.

Out of curiosity, did you also relieve the fuel pressure at the fuel filter? Or did you just undo the battery, pull the fuel lines and go at it?

#135599 you definitely have to bleed the pressure off, the best way is just to kill the fuel pump (i have a cutoff switch) and run the motor until it dies, then you get <5psi of pressure and then your good :thumb:

but you can also relieve the pressure at the service bolt on the fuel filter...if you let it sit overnight it usually drops some pressure as well

#310109 I have a 1994 Civic EG8 (4-door sedan) with D15B3 engine which has carburetor and I think the fuel pump is mechanical. I'm going to swap the engine with a K20A and I'm going to need an electrical fuel pump installed. Please help me in this! What parts I need to purchase and what modifications should be done?

#335186 Installed mines yesterday, thanks for the info. :thumb:
the metal lock washer thing for the pickup bag was the hardest thing to install, i ended up reusing the old one because the one in the kit was impossible to fit..
