Posted December 30, 20213 yr comment_633671 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.

December 30, 20213 yr comment_633675 Purple power will do that to aluminum. You should be able to glass bead blast it, or possibly scotch brite it to remove the oxidation... and still use your old one.

December 30, 20213 yr comment_633679 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.

December 30, 20213 yr Author comment_633684 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.

December 30, 20213 yr comment_633685 I've had good luck with one of these on small stuff. Baking soda is cheap but you need an air compressor and spray gun.

The VHT paint is a good fall back…in stock at my local Autozone. Thanks Jim 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.

December 31, 20213 yr comment_633697 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.

January 23, 20223 yr Author comment_634786 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.

January 23, 20223 yr comment_634787 I used this on my last SU rebuild and they look great. It's a polishing wad, whatever that means, wipe it on then buff it off.

January 31, 20223 yr Author comment_635123 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?

January 31, 20223 yr comment_635132 Grease it lightly with regular axle grease and the lubricating oil comes from the engine. Link to comment https://www.classiczcars.com/forums/topic/66196-wanted-nikki-271070-fuel-pump/#findComment-635132 Share on other sites More sharing options...
