Wanted: Nikki 271070 Fuel Pump

Hello 

i am looking to buy a Nikki fuel pump for my 1972 240z. Part No 271070 (as seen on pump housing.) See photo. Just about any condition is acceptable.

My rebuild, as discussed in my previous post, was going great. Prior to final assembly I decided to give it a good degreasing. The degreasing bath I used was much to harsh and destroyed the finish. So back to the drawing board. Now instead of the nice aluminum finish, the housing is a dull dark grey…a costly mistake.

Thanks.

Jim

Glass beads will work, as will a wire brush. Brass or SS. Cleans up aluminum very nicely. Then an oil based sealer like Gibbs to preserve the finish. I’ve even used the cast aluminum caliper paint from VHT.

That is good scoop. I do not have ready access to a blaster…how about a Tumbler? Will that work? The VHT paint is a good fall back…in stock at my local Autozone.

Thanks

I'd stay away from tumblers because aggressive media can round off screw threads and sharp edges of the component.

I really like my ultrasonic cleaner.  The one I purchased is large enough to easily clean the body of an SU carburetor and make quick work of years of grease and crud build-up.  I'll make a solution of 1 part Simple Green to 4 parts water and put it in a clear plastic zipper loc bag, along with my parts.  Next I'll put it in the cleaner and fill the of the tank with plain water.  It also works great to keep jewelry nice and shiny. 

It has paid for itself is time saved in labor.

I own, and use, both a soda blaster and a larger version of the ultrasonic cleaner pictured above (both inexpensive Harbor Freight products), on Z aluminum castings (carb bodies and fuel pumps). Both work well, but one thing I learned is there are two versions of Simple Green, one green and one purple (both available at Home Depot). The green one will etch/dull the castings, with soda blasting the best way to counteract the effects. The purple Simple Green product says right on the container it will not etch aluminum, and I've found it works quite well when diluted 5 parts water to 1 part Simple Green/Purple.

Just had my Nikki fuel pump Media blasted. It looks much better, perhaps a bit dull. I will take the advice in the previous post and use some Gibbs oil based sealer. Thank You all for your help.

Getting ready to reassemble my original Nikki fuel pump using the rebuild kit I acquired. The rocker arm assembly needs to be lubricated and when I first disassembled it there appeared to be some lubricating oil present in the lower body of the pump. Does anybody know what type oil is used…regular motor oil, gear oil…???

The service manual does not say anything about this, although the Haynes manual says to grease the rocker arm assembly.

Thoughts? Comments? Definitive guidance?

Thanks

Jim

that is awesome looking. Mine is almost reassembled, but does not look as nice. Looks like you zinc plated some of the parts and screws. Is that the original finish or did you paint?

Add a dab of white paint over the center screw on the cap.

Ha! This is sitting in a box.

Yes, I have been sending parts off to zinc for years. Cheap and easy.  The finish is vapor blasted.

A couple more quick questions about the Nikki 271070 Fuel Pump.

What type screws secured the body halves and cover? I have seen two versions…standard Phillips head and a slotted screw with a cross slot similar to a Phillips but definitely different. (Sorry I do not know the name of this type screw head.)

I have also seen two different type covers. One is plain other than the Nikki brand name. The other has two small rectangular raised areas. 
 

Are there different versions of the Nikki 271070 pump that might account for these differences.

I have attached a couple photos showing the differences.

Thanks

Jim

I'd guess that the bottom one has JIS screws, which require a JIS driver to avoid ruining the head.  Top one may have been disassembled at some point in its history, the PO used a Phillips screwdriver, trashed the heads, and replaced them with Phillips screws.  All just guesses on my part - possible someone else on the forum has more definitive information.

26th…

I read that article before making my post. Was able to confirm the likelihood that my 2/72 Z was equipped with a NIkki. The article mentions some differences in the screws and cover but does not really give any definitive guidance.

most of the Nikki pumps I have seen have the screws the same as the second (bottom) photo in my original post. While many I have seen have the two raised rectangular areas.

Hoping somebody can provide some definitive answer.

Thanks

Jim

Jim, curious about that battery terminal.  Looks like a British one that I would like to find a source.  Where'd you get that?  🤔

Ha!  Never mind, I figured it out!

I had those on my boat. Heavy duty crimp on battery terminals. They have some that have screw down instead of crimp.
