I saw this on eBay: Nissan Hitatchi Su Float for Datsun 510 Roadster Z Car and Others | eBay

That don't look like no SU float I ever seen.....

It's for an SU but not the ones on a 240Z. Good thing there was a photo. Might fit 510's.

Those are for the Roadsters.....I need one. I opened mine up and one looks like this pic, the other is all metal (brass I think). I think the all metal float is early roadster vintage and the pictured one is late model vintage.

These are the free floating floats for the 38mm carbs (2 bolt mount to the manifold)...... Those brass floats have a nasty habit of developing tiny hair line cracks, taking on gas and sinking like a rock.....

Still nothing available for Z car floats as far as we know.....

That's too bad. I was hoping they found some lying about. If it sounds too good to be true, it probably is too good to be true.

Can't believe nobody's making floats for the 240Z's. It's not that complicated - seems like the tool-up cost would be so low you could sell them for $5 each and still make a profit, $20 a pair would seem OK. I've seen some Chinese (I know) manufacturing company's sites that say something like "send us your CAD drawings, we'll send you a quote, 200 items minimum production..."

One of you guys need to jump on this...... Small two or three stage die set for the metal piece and mold or molds for casting the floats them selves. Anyone? ANYONE?

We alone would probably buy a dozen or so a year.....

We did identify the resin used for the injection molding process if that helps......

Only if you let us know what resin it was.

Bruce, what is it about the existing floats that make them need to be replaced? Aren't they solid material? It is something to do with the metal frame? Are the float bodies deteriorated? Can't imagine ways to help unless we know the details.

If its the resin that needs replacing, I was thinking about other ways to replace just that part.

Precisely weighted ping pong balls? Styrofoam? Just need something with the same density, yes?

I'm flush with ideas once I get going!

We see all kinds during tear down but primarily it's physical damage from errant tools splitting and gouging the foam. I'm also hearing that floats are being degraded by today's gas i.e. soaking it up and getting squishy. No one has sent their squishys in for us to look at so can't testify to that but we are still waiting to see some real cases of "come over here Vern, and look at this".......
