Fuel Pump
I'm new here so I will make a deposit to the forums search queries, I did a pretty big Fuel System Upgrade Saturday. As seen in the Pic, I installed a Walbro 255LP Fuel Pump, NISMO FPR, and a Fuel pressure Guage.
First things first, with the car running, remove the fuel pump fuse and let the car die out.
Let’s do the Fuel Pump first. This was easier than changing the oil in my opinion. In my specific car, the Fuel pump is easy to get to, it’s in the trunk. Juts lift the cover for the spare tire well and remove the bolts that cover the Fuel Pump carrier/harness. Then disconnect the wire harness that is connected to the Fuel Pump carrier. Yeah it is a bit dirty in there:
Before you can remove the pump you have to take out the (2) fuel lines, don’t lose the clamps, on my car if I wasn’t carefull, they would be gone forever…Be carfull when removing the Pump from the gas tank as not to damage the fuel level Bobber, you gotta turn it this way and that way but eventually it will come out. Also do not let any of that dirt fall in, that would be the sucky..Make sure you cover the hole to the gas tank with a magazine or newpaper so no debris can get in there. Once you have the Fuel Pump carrier out you can ensure the new pump you have is supplied with a power wire and a ground wire..if it is then you can cut the stock wires off, leaving enough to splice in with the new pumps wire harness for power and ground. Here is a pic of them together after, the red and black wires are the ones you cut:
If your new pump does not come with fuel line, buy some..it’s best to use new line. After you cut the old wires, set the new pump in the carrier…When you put the new fuel sack on, there is a little washer that holds the sock on the pump, be carefull with this thing as it is fragile and the only thing that holds the sock on the pump. Then put the rubber grommet over the sock and it is rady for the carrier…After the pump is in the carrier try to get it in as tight asyou can, using the fuel line to move it up and down, this way you can force the pump to stay in the carrier..Some people use zipties to get it tight. I didn’t need to, it fit nice and snug.
Then splice the power and ground wires from the new pump harness to the carriers wires…
Then it should look like this:
After that, just put it back in using the reverse order.
