Fuel Pump write up with pictures

I found a few write ups but none with pics so here it is



Disconnect your battery. Then the fuel pump access door is behind the Driver on a USDM spec FD. Lift up the carpet and you'll see it. If you have a Bose stereo system you'll probably have to remove it. There should be 4 screws holding the door down.


Lift up the fuel door and unclip the wiring harness


You can either unclip the ground or unscrew it i went with unscrewing it.


Set the door off to the side and unscrew the fuel line connectors


Clean off the area for obvious reasons


Take all the screws out of the fuel hatch


You'll need to push the 2 fuel lines out of the way. The line on the right hooks into a clip i found it easier to pull the line of the clip so you get more play in the line


Lift out SLOWLY as to not hook the float on anything


Remove the screw on the back of the rack, mine was extremely tight


The + and - wires are different sizes so you can't really screw that up but hey maybe you can. I left 1 wire on just to make sure i didn't


With the new fuel pump make sure and hook up the fuel bag thing
by pressing on the washer


Put the spacer and O-ring in the fuel neck

Put the fuel pump space and cover on the fuel pump




Tadaaa


Put it all back in the car and start her up. I let my car idle for quite a while to make sure there was no air in the fuel lines.

Please add in anything i might have forgotten.

Great write-up. Thanks for going to the trouble. Good point on cleaning the area around the hoses and hatch before removal.

My only comment would be to make sure you also get a new screen ("fuel bag thing"). I assume the FD is like a couple of other cars I've had this experience with, where the screen is purchased separately. Personaly I wouldn't install a new pump without a new screen...especially since they're usually less than $10.

You can replace the stock FP with another stock FP but I put in a Supra pump same size as the stock pump, this would also work for a walbro.

i went with a cooling mist unit, i think if i could go again i would go with aquamist, they seem to make the unit alot smaller, so you can hide it lol.. i got the one with the gauge, its good to have i guess, tells me either boost/what % the pump is pushing/volt/ or flow rate if i had that thing for it.
