200$ shipped. Nikki 2.4, 2.6 and 2.8 fuel pumps. Most of the parts are Nos. All internals are new. Only issue is the zinc on the hose barbs don’t perfectly match the screws. Base that attaches to the block and hose barbs are the only parts not NOS. PM me.

Rather than clutter up prior threads on rebuilding the Nikki fuel pump, let me raise this question: can a Kyosan Denki rebuild kit be used for a Nikki fuel pump? We have two great articles on the rebuild process, one from Arne in 2009: http://www.classiczcars.com/articles/fuel-system/rebuild-a-240z-mechanical-fuel-pump-r70/ and one from motivealloy in 2014 that is currently active: http://www.classiczcars.com/topic/50679-rebuilding-the-nikki-fuel-pump/ At least one of these articles stated the Denki diaphragm is "different" and will not work. The Nissan P/N for the diaphragm is discontinued and NLA and in motivealloy's thread I recently asked where to locate the Nikki rebuild kit but got no answers. In that thread, Darrel provided a link to rebuild kits from New Datsun Parts - that kit is for the Denki fuel pump and one that I purchased. Checking the pictures below I pose this question: I know the Denki diaphragm and oil seal look different but are they different in a manner that makes them functionally unusable? The primary difference on the diaphragm is in the fitting that locks in to the pump arm - doughnut vs. T. The tab on the edge of the diaphragm has a different orientation but that is external, all other dimensions are identical. The Denki oil seal is a boot that is a perfect fit for the Nikki body and is held in place by the diaphragm spring. I've searched extensively for a Nikki rebuild kit but no joy. So... here's the challenge to the experts: point me to Nikki rebuild kits or tell me exactly why the Denki kit will not work. Thanks!
