There is a vent valve that is closed when you have the fuel cap off. This is an artifact from the gasser design where it is needed because gasoline expands greatly when external temps heat up. Diesel does not need this safety feature.Please explain venting. Is it possible to vent a 2001 Jetta? I don't see any valve as mentioned on other posts. Maybe a PO removed mine.
i don't vent. except i'm about to if this thread is hijacked any further.If you really only get 12.5 gal while venting after the low fuel warning goes off, then it is set to trip at around 4.5 gal. It's supposed to be around 1.9 gal.
hijacked?i don't vent. except i'm about to if this thread is hijacked any further.
not a measurable amount...
Does glow plug issue reduce fuel mileage
The glow plugs can misfire, I would check your coils, wires and distributor also....and make sure the Carb is clean.How many gallons does your mk4 golf take to fill when fuel buzzer sounds. Mine is 12.5.
Does glow plug issue reduce fuel mileage
I think he's joking since a) it's a pun, and b) it obviously is relevant to his thread. Although it can be hard to tell over the net.hijacked?

I have gone 58 miles once the light came on during a highway trip. Once the light came on I lowered my speed to 60mph. I can look t my fueling log, but if I recall correctly I put in 15.45 gallons of fuel!You could probably do another 50 or 60 miles before running out (but it's impossible to know without finding out the hard way, which is really not a good idea at all).
You mention brimming, but do you vent as well?
Is the inlet in the same position? For example, if it is higher in the estate then that may be where the extra volume is coming from.Same part number in ETKA. Who knows? It does seem that people get more fuel in the wagons.
^^^^^^^^Without venting it's difficult to get consistent fill-ups. Search for ventectomy here, or simply look in your car's filler neck: You'll see a little black nub on the left side of the neck. Push it towards the center of the car using the wire wrap on the fuel nozzle and you'll get additional fuel in the car. Fill it until you see solid fuel (not foam) in the neck. This can take some time depending on the station. If you do this consistently you'll get much better data on fuel economy per tank.
I've put 16.9 gallons in my wagon at times. 15.5 right when the light comes on is normal.
I've done 17.26 gallons I wouldn't do it againThe most I ever pumped in my 01 Golf was just over 17 gal, and this was without running out of fuel.
