I am looking for a rebuild kit for my 1972 Z car mechanical fuel pump. The original equipment model is a Kyosandenki. i am trying to keep the original unit and do not want to go to an electric pump. There are a number of replacement options but i want to rebuild this one. Have checked all the sources i can think of without success so far. Wondering if i'm on a fools errand. Any leads would be greatly appreciated. 

yeah, four screws were out for the photo. oops. 

Check this link to see if he still has the 'Denki kit, note he also has valves listed below the kit.

Thanks, JIm. That's a good site that I had missed. they didn't have a rebuild kit under the 240Z category so I checked the 1500, 1600 and 2000 parts.They have a kit that also works for Fairlady but only up to 1970. So, still looking. Many thanks for your post.

That kit is listed under the 240Z parts.  I used the same kit to rebuild a 240Z 'Denki.

OK Jim, thanks again. found the parts and ordered. Shipping today. Website even responded on Sunday.

additional info.

I also remember a post about using a certain Toyota pump that is still available through parts dealers, like RockAuto. Identical internals, just steal the diaphragm and valves and plunl them into yours. I ordered and used one once when that thread came up. At least 5 years ago I think. I wonder how far back my RockAuto order history goes....

 

Checking RockAuto for 72 240Z, there are a couple of pumps that look like stock ones, a GMB and a Delphi. I wonder if their diaphragms and valves are interchangable with the old stuff. For $43 CAD, might be worth a try.

 

I should cull through my old pumps, disassemble and get all the old diaphragms and valves out and see what looks usable still.

Thanks, zKars yeah I saw some GMB and Delphi items that might work as cannibalization options as well since i'm trying to keep my original unit. I my try that route if the new Datsun parts.com source doesn't work out.

Per a Carl Beck mention back in 2017 if you are replacing the whole pump the GMB 550-8040 is compatible with (and a Denki lookalike) the early Zs and runs about 30 to 35 bucks on ebay. in my case, i wanted to keep the unit and just replace the guts.
