Quick Help Regarding Fuel Pump!

[blk94r33]

Hi all, will try to be as brief as possible.

Original problem:

-Fuel pump has been noisy in car since purchase, never gave trouble, just noticeable when priming or with the back seat out.

-In the process of re-doing my boot install for more "oomph" and boot room using a custom box, I need to seal over the pump access hatch with seam sealer.

-After this, changing the pump if it dies will require 2-3 hours work to access and re seal the hatch.

Solution:

-Bought a Walbro GSS-341, which will support any future needs power wise, and prevent the current pump dying down the track.

New problem:

-Went to fit the pump tonight, after removing the assembly the pump is at least 2 times bigger than the Walbro:

And has these markings:

Jecs A42-T02 12v

* 000 4222

Made in Japan

The * denoting the Nissan branding with the rectangle and circle.

From a quick search on google and here, I established that Jecs is like Bosch and makes OEM electronics, but the numbers don't match anything?

Is this pump the original, 160,000 km old item, a genuine replacement, or an upgrade?

Should I still replace it with the Walbro item?

Any help appreciated as I'm trying to get the car back together now.

Looks like the standard fuel pump

The Tomei pump i put in was smaller then the standard pump, not by as much as the walbro but it was slightly smaller I remember that much

I assumed it was the original with the Nissan/Jecs brandings. Walbro's in now, much quieter and is doing the job thus far. I guess 17 years on things don't need to be as bulky anymore...
