Andrew,
Most 1600's in Aus actually came with a sealed fuel cap but the fuel system
was vented through the floor like yours. I'm not sure of pre '69 sedans, I
think these (may be only some) had a vented cap like Holdens & Fords of that
era and I've seen both systems in a wagon so I'm not sure what's the go with
them (I never really got into the idiosyncrasies of wagons).
I've only ever seen 3 or so 1600's with a fully sealed fuel system (one was
at a wreckers here so I had a good sticky at it) which also came with the
rest of the ADR27 or was it ADR27a (I forget which one) anti-polloootion
gear and these must have been private imports from Asia. The late model 180B
was the first Datto in Aus to come with a sealed fuel system which is quite
similar to the US Bluebird 510.
The sealed fuel system was extensively used in the US (California spec)
Bluebird 510 (1600) which have an separator tank on the top of the fuel tank
with more hoses on it than you could think was useful, and a "T" piece
(which is actually a valve) bolted to the nearside strut tower that has some
hoses connected to it, one comes from the tank and the other goes to the
inlet manifold and the third hose goes to the air cleaner so the fumes from
the tank get sucked into the engine and burnt.
All cars in Aus from around '75/76 have a sealed fuel system as standard -
you no doubt have heard the pssst sound when a cap is taken off in a petrol
station. If you can get hold of a Scientific Publications Manual for a 510
(#88) there is a good diagram of the US spec sealed fuel system on page 251.
regards
Terry

Subject: fuel filler caps -TERRY?
hi list
a while ago terry mentioned that there are two different fuel filler
caps used - a sealed one and a vented one - depending on what
year your 1600 is.
I was wondering if anyone knew how each differed in appearance,
because by the info in the archives my fuel tank is of the sort that
has a breather through the boot floor and therefore needs a vented
cap. Yet it has no apparent venting mechanism and appears to be
of the sealing type!!
Thanks
Andrew
