This week I finish up the Toyota big brake upgrade on the 680g.

 

 

I guess I missed something along the way.  Why do you call it the "680g"?

24 ounces = 680 grams

240Z = 680g

Isn't Australia on a different standard?  Imperial maybe?  Then metric.  I get 675.  Or 750, depending on source.  Weird.  Cleverness gone awry.

https://www.nisbets.com.au/conversioncharts  3 x 8  = 240, 3 x 225 = 675

https://www.taste.com.au/healthy/articles/weights-measurement-charts/vnepuhic#cup  3 x 8 = 240, 3 x 250 = 750

 

Looks like Jeff used the US conversion - https://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-weight

Found this while I was looking around.  Kind of funny, but not really.  https://www.nist.gov/

 

 

Imperial and US ounce are the same I think. Wiki agrees https://en.m.wikipedia.org/wiki/Ounce I think we just deviate on how many ounces are in larger units like pints and gallons.
An ounce is 28.3 g, so 24oz is 679.2g

Ok, I get it now.  It just made me scratch my head every time he called it the 680.

Could have used Troy.  I still have memories of the US attempt to go metric.

The table in your link was interesting.  Alrighty, back to building the 24 Oz.

I remember the metric alphabet. It would have made things so much easier. The decabet:

In this episode I install the electric fuel pump and tidy up some more of the engine bay in the 680g

 

 

 A word regarding electric vs mechanical fuel pumps.

There is absolutely nothing wrong with the mech pump, throw what you want at it, dcoe 45? no problemo

So why electric? there is one and only one reason,  in my particular case, I incorporated it into the security system, in other words unless you know the secret hand shake ......the perp will be stalled in 50 feet or so with no fuel.

Regadess, and as been my experience a few weeks ago I have been driving the 240 and it died about 1/4 mile from my house as if its out of gas, which it wasn't, reluctantly I have suspected the supply hose/s  at the fuel tank, both were 100% original and super brittle, both got replaced.....yet  the problem remained. finally, I replaced the hose from the fuel rail (100% original)(pass side fuel rail to the fuel pump) and that did the trick.

Moral of the story: Don't wait 45 year+ to replace  any flexible rubber fuel lines, the factory stuff may last that long (not) ..but aftermarket?

GREAT VIDEO!!!

You may wish to double check the fuel hose location against the carb linkage when it moves to its full excursions.

In this episode I have a go at repairing the dash and also modify and fit an accelerator cable to my Z.

Jeff,

Did you see any of the threads on the forum about dash repair? A number of people have had good results with filling the dash and using SEM products to recolor and texture the repairs
