Syncro T3 Fuel Tank capacity.

G'day,
Hope this has some general interest.
My recent trip West had me filling up when empty or available. On one
occasion when the gauge was showing nearly empty the tank took 76.6
litres without taking the special time consuming efforts necessary to
squeeze in the last few litres. I was a little surprised (and
suspicious about the pump metering) as I understood the T3 had a
70lire tank.When I aired this with the service station attendant he
said he had the same feeling when he filled his own tank.In normal
motoring I'd be unaware of this but it was the only time I've put in
over 70 litres unless I was also filling the unconnected additional
tank in my car. The forecourt was flat and the temperature was around
15 degrees C.
I rang the petrol company on my return who referred me to the grocery
chain concerned and they said they would check and get back to me.
That was well over a month ago and I am wondering if a follow up is
warranted or as they remarked at the time its likely to be the built
in expansion factor.My Bentley manual shows 2 nylon? expansion tanks
in addition to the main metal one and my factory handbook states the
capacity as APPROX. 70 litres. Interesting? Does anyone authoritively
know or can point me in the right direction to avoid egg on my face if
I follow up? Had no luck with a Google search.
Thanks

Gday Roger, fantastic photos of your WA trip, thanks for sharing. I
would love to do it someday.

Two questions please.

My wife says she doesn't want to drive across the Nullabor ... too
boring, rather catch the train. How do I change her mind? Woman! Bar
humbug!

I have a straight syncro trakka with either standard 14" rims and road
tyres or 15" rims with offroad tyres, no difflocks or decouplers. VC
seems fine. In your opinion, could it fail to go where you did go in WA,
particularly in those mud, sand and water locations, seeing as you also
have a rear difflock? TIA. Cheers.

hi

Sounds like you got ripped :-(
I have never ever put more than 70l into the tank. that includes
travelling in extreme 45C to -20C.
Maybe your tank is a tad bigger?
Expansion? A guess (GUESS!!) would be less than a litre.

Anyways is it worth the trouble for $10?...yeh get the bastards.

and your right about the Syncro. Best car on earth!!

Roger,
 
The original owners handbook that came with the Australian Syncros says that the tank capacity (page 145) is approximately 70 litres. 
 
Bentleys (Technical Data, page 27) puts it as follows:
Fuel Tank
(total with reserve)        60 litres  (this refers to the 2WD vehicle)
Syncro:                        70 litres
Reserve:                       10 litres
 
Yea, very helpful !!
 
Soon after I got mine, I put more than 70 litres into it at one filling.  I posted a query about this and i think that it was Phill who explained that the total was in fact 80 litres.  Since the rate of filling above 60 litres must be measured on a calendar, not a stopwatch, I have not had the opportunity to prove this conclusively but will do so some time in the future.
 
The construction of the tank filler pipe is such that there is a considerable volume above the level of the filler pipe and filling above this level (up to a compleltly full tank) depends on the two one-way valves in the top of the tank performing as they were designed - allow a full fill but prevent leakage in the event that the vehicle (heaven forbid) is on its side. 
 
It pisses me off no end that any filling above 60 litres is at glacial rate.  This is known around the word of Syncro owners, to the extent that some owners carry 4" thick blocks on board.  When they fill, they run the two RH side wheels up onto the blocks.  This raises the relative height of the filler pipe and they are able to get most of the tank full.
 
I have not had any reason to drop the transmission, which is the only way to drop the fuel tank, and then be able to thoroughly examine the one-way valves - and also the absoluite capacity.
 
Has anyone actually done any of these things?  Phill?
 
Les

Hi everybody,

the german Handbook says 2WD 60l, syncro 70l. (10 litre of each are
reserve.)

http://vw.dnsx.de/archive/betriebsanleitungen/Transporter_und_Caravelle_89/.tmp/640x480/seite043.gif

I think the tank capacity is a little bit higher. My refilling record
with empty tank is 73,6l petrol.

Thanks Ken
I hope you do indeed get to do something similar in the forseeable future.
Regarding your questions
1. Take your wife in the wildflower season although my wife (and myself) were enchanted by the range of Banksias and other flora even in winter. Call at the Port Augusta Arid Plant Botanical Gardens; Watch whales at the Bight. Do all the things that Andy says and say hello to him in Ceduna.
Consider going 1 way by rail as most of the time the track is further inland.
Finally I should pass on that my wife remarked as we got back to the Eastern End of the Nullabor " It really didn't seem that long a distance coming back"!
2. This may be related to Qn 1 as I found my wife had a constraining effect on my desire "to go where no man had ever gone before." which probably ensured my T3 is not quietly rusting on some beach with the tides washing through it. I did have a few "moments" on the St Anne beach which had very fine sand.I kept digging in when trying to get out over the hill of the sand dune track but easily got out when I let the tyre pressures down. There were also some deep and churned up sections of sand in the Francois Peron national park which had me down in the "G" crawler gear and struggling a little even with the tyres at 24 psi. I was loathe to go to the recomended 16lbs as I didn't have a compressor with me. 99% of the time 2WD is adequate  and therefore I wouldn't think you would be very restricted ie even without a difflock you can get most reasonable places but do take a compressor and some recovery gear and remember that even a double difflocked Factory 16" can still get into trouble. (See picture of Derek Drew bogged with both diffs locked and chains on all wheels-That man makes me seem such a wimp. <http://users.rcn.com/derekdrew/Syncro_Madness_Area.htm>
On a different tack when younger and even sillier I had  a Peugeot 404 station wagon and used to take great delight in amazing 4WD vehicles where it would go with a set of chains on the rear. Perhaps chains are a cheap but less convenient alternative to a diff lock.
Final comment - The sole other camper at St Anne's beach was an elderly  bird watching lady in a  syncro camper conversion on a T4 Caravelle. She said she found it perfectly adequate to take her to all the places she had been restricted to getting to in her previous toyota high ace.I think they might have an electrically operated diff. although I had some doubts she would use it.
Thanks to you and the others for their responses.

Gday Les and all

Thanks for this Les, very informative. Space and extra weight is such a
big issue when tripping around in a trakka. I weighed it the other day
on a weighbridge and it was just over 2 tonne. And that's with it
unladen with what has to go onboard for a trip .... hell! So carrying
extra blocks on board would be a no no for me. I don't see a problem
when on those occasions when you do want a full tank, simply jack the
car up at the petrol bowser at the rear jackpoint on the fuelcap side.
Sounds too easy to me. Any problems with that solution Les? Cheers.

Hi Les

 

I have recently explored this “slow fill syndrome” when converting my engine to Subaru 2.5 L. The transmission was out and it was opportune to pull the fuel tank out and investigate the venting of the tank. Incidentally it was quite a challenge as I discovered that the plastic tank over time had expanded and deformed its shape so it was a “tight fit” requiring much leverage with long tyre levers.

 

The mail function of the two float valves is to vent the fuel fumes due to pressure build up, to the charcoal canister and to prevent any liquid fuel entering the canister when “over filling” (a thing most difficult to do!) It is a closed system as the output from the charcoal filter goes to the intake port via a vacuum valve. Hence there would be no spillage to the out side in case of a roll over even if the vent float valves were open – this has to be a design criterion. If the syncro was indeed on its side or up side down (heaven forbid) the valves would not operate as they are float valves – on its side the float valve could be open until hydraulic lock closed it – upside down the float valves would be open until again hydraulic lock would close them.

 

The tank has a main breather tube (13mm Φ) that vents the tank into the fuel filler neck when filling. It is located on the filler side of the tank and slightly below the level of the float valves. That is why the last 15L to 20L is difficult to fill. Hence by lifting the vehicle on that side (by 4” block or jack etc) the remaining vapour pocket is vented and a full fill is achieved!

 

The two hoses (10mm Φ) from the float valves do partially vent the tank when filling but this is restricted eventually by the 2mm Φ purple plastic line coming out of the charcoal filter valve – in effect the last part of the tank is vented by a 2mm Φ pipe! Hence Les the need of you to “measured on a calendar, not a stopwatch “ the time to fill the last bit of the tank.

 

Now after all this I have a solution that would interest most Syncro owners. To overcome the restricted venting of the last 15L – 20L is to introduce a bypass hose. Tee into the 10mm Φ fuel tank vent line just above the charcoal canister and run this bypass hose over the transmission into the engine bay and into rear RHS cavity where the main 13mm Φ tank vent hose is located. Tee the bypass hose into this as close as possible to the fuel filler neck – it must be higher than the tank. Removing the tail light assembly will give access to this vent hose. This bypass hose will vent when filling otherwise when the fuel cap is on pressure build up is handled through the charcoal filter in the normal way.

 

The capacity of the tank is 80L - though mine is about 82L due to tank expansion.

How about a vent with a cap or a tap on it?

Yurik,
 
Thanks for the excellent posting on the slow fill and venting problem.  On the face of it, your solution looks very sound and I will look into it as soon as I can.  I was most interested to read about the tank distortion; that had never crossed my mind.  A report on the 2.5 Subaru installation would be of interest to many list members.
 
Ken,
 
 Your solution certainly works - people in the US do this - but the only time I would jack up the Syncro on a petrol station driveway would be at 2AM - and even then, they would probably call the police.  Seriously, a couple of 4" wooden blocks (preferably with a ramp on one end) is not a silly solution.  It would only take 30 seconds to stop, pop a block under each RH wheel and drive onto them.  Overseas postings indicate that you can get it nearly full at normal pump flow.

Hi Les

I have recently explored this “slow fill syndrome” when converting my engine to Subaru 2.5 L. The transmission was out and it was opportune to pull the fuel tank out and investigate the venting of the tank. Incidentally it was quite a challenge as I discovered that the plastic tank over time had expanded and deformed its shape so it was a “tight fit” requiring much leverage with long tyre levers.

All,
I take the easy way by filling at service stations that have a
driveway that leans to the left and forward (as well as cheaper fuel
prices). I have a few around my area, It works well.
Regards
Rick.
