Here is pic of what mine looks like. Build is 12/70 RHD Aussie model.

As you can see, it must take some acceleration to get fuel out the vent. Must be hard to get it up over the loop wouldn't it? I guess a lot of slosh would help it.

So that gets me thinking, did the fuel tanks have baffles to help reduce slosh???

ok mine doesnt look like that. notice how the hose loops right up. mine is pulled tighter so the hose basically doesnt go any higher than the filler neck. you should really check this out to see if it does loop up higher as that would definitely help out, im just waaaaay to lazy to do anything about it.

Your fuel system looks just like Mark Brandyberrys (one of the first 500 Z's to reach USA, mfg'd in 1969).

As far as baffles, the USA model 240Z tanks that I've observed only have the support ribs about 2" tall along the bottom of the tank. I would think that they would only "help" a little bit in minimizing sloshing. Other than that, the tanks have been wide open (no baffles to speak of). When our tanks are full, the fuel level is already pretty far up in the fuel filler tube and some of the vent hoses have a lot of liquid fuel in them as well.

on my last post the vent line I was referring to is pictured as # 8 on bambi's picture .

...Is the plumbing the same for 70/71 and 72 build cars? or was it only introduced with the electric pump in 73 [for US bound cars]?...

the evap tank started with the 72 b/c of the new emissions requirements

Absolutely, 100% NOT true!

The evaporation tank and venting was installed on ALL but the very earliest of the 1970 model 240Z's. I have owned an early 71 model 240Z's (mfg'd in 1/71) through 1973 model 240Z's (mfg'd 3-73) and ALL of them have had evaporation tanks.

There were two different versions of the evap tank, both located in the same place. The early version of the tank was plastic, and was replaced by a metal tank. The switch in tank styles occured sometime in late 70 or early 71 from what I am told. My 3 240Z's (71,72, and 73) have all had the metal tank

Here's a picture of the early tank, I don't have a pic of the metal tank in my files yet.

^^maybe that's what i read... i just remember reading something about the 72 being the first year for the tank.. perhaps i misread it... i stand corrected

Here are a couple pictures of the metal evap. tank I sold on eBay from 1972 parts car. My Series I tank is the plastic one I guess, never looked. Gary
