240Z fuel pumps - How many different OEMs?

[Arne]

Atsugi? Oh my! A fourth brand! Can you get us a picture?

FWIW, Atsugi also supplied the water pump.

Cool thread! I'll check my cars.

As one might expect, the fuel pump is missing from 27th. I spent the day oiling her yesterday. I figured that if I oil her periodically, she will come apart with a little more ease. I'll tell ya, those rust brothels in Delaware must be brutal. Next time your'e visiting a porn site, imagine what those women are going to look like in 40 years! Eauwww!

26th doesn't have a much better story in terms of fuel pumps. Her Denki fuel pump was spitting oil the last time I drove her. This was well before I came to realize the importance factor of date codes and original original correctness. So, at the time, I just drove over to International Auto Parts and bought this Nikki from Sam and Mahty. It came from Bap-Geon in a Bap-Geon box. The set screw in the center is painted white and notice the difference in the body casting between the two. The Nikki cap is different from other examples also. It is smooth with no raised castings for an A2 stamp. The ink stamp on the base is 1-6-3.

Thanks, Chris. The addition of your info now makes me think that Stephen's Nikki (see post #4) is not original, but is a later replacement. Same smooth cap, no raised bosses, no stamped numbers, and white paint on the center screw rather than the yellow of the originals. Very interesting!

Ok, I realize this post is rather old, but I found my Z's original fuel pump and I thought it might add a bit of info to this thread. My Z was built in 3/72 and has a code on top that reads "1Y01". From what I gather, no one in the club knows exactly how these Nikki codes relate to the date the pump was made. I'm guessing my pump has a late '71 code, but who knows. The pump has a part number of 271070 cast into the side, and also has a small bit of yellow paint still visible in the middle of the screw on the top cover. I got the pump in a box of parts that came with the car when I bought it from the original owner's son. I installed the pump and it will only supply fuel up to about 3,500 rpm, then the engine starves for fuel. The spring that puts pressure on the pump rod is weak...can these original pumps be rebuilt?

1101 Jan 71

even better: the dash has a date of Jan 9, 1971 (a saturday)

Awesome stuff!

Our 1971 FairladyZ-L was supposedly made in May 1971, taking a guess at the spread of production numbers for that year.

The original fuel Nikki fuel pump is stamped "1501"

That would seem to fit the scheme if it is indeed a 5/71 car.

What do you think?

Sorry for the dup post ... too early in the morning!

Confirmed the build date of May 1971 recently with other dates on the car. Just an update.

Yes. I just cobbled enough parts to rebuild my original, except for the spring. I've that on order from NISSAN PARTS. We'll see if they can get it. The aftermarket pump on it now is putting out too much pressure so I'm adding an inline regulator to hold it down to 3.5 psi until I can get my original rebuild accomplished.
