Walbro 255 Installation DIY (3.4 Mb)
 
I replaced my stock fuel pump with a Walbro 255 lph. I searched this site over and over to get some information on how to do this and came up with just a few scattered snippets. I thought I would document my adventure for the next guy. Here goes...

First - Remove your back seat. The pump is on the passenger side.
Remember to never force anything. All these parts are made of plastic and easy to break.

Put the assembly back in the car the same way you took it out.

That's it. It should take less than an hour to pull this off.

The Walbro pump provides three times the volume of fuel. I needed it because I installed a Greddy TT in the car.

No. The pump has the same connector as OEM.

Is transferred to the new pump, which you did do. I just didn't see mention of it.

Very nice pictorial and write up as this should help a lot of people understand how this is done.




This should be a sticky.

sliderg35 12-02-2007 06:08 PM

I added a note in the original write-up to show where the rubber adapter is moved. You'll need to click "refresh" to see it.
