Thread: Fuel tank capacity?

Guys,
The vehicle does NOT self prime
But we have worked put that if you turn the ignition on & let runs for 5sec, then off, then on 5sec, then off, then on5sec etc. for approx 10 cycles the vehicle may actually prime itself.

But..

If you remove the engine accoustic cover & at the rear of the V in the block you will see a schraeder valve with a cap (tyre valve), this is the fuel bleed system. Push in valve & turn ignition on & when you have just fuel & no air bubbles then all should be ok. Preferably a 2 person job.

Cheers.

I can confirm that Sneigy's first method works, as long as you haven't continued to drive well after the first one or two "surges" from the car!



Cheers,

Thanks for that info re bleeding.. Is it in the FAQs? Probably should be.

Discojools.

I have noticed that the dash readouts seem very cautious in the D4. I have only got a maximum of 69L in the tank readng 60 something to go. At these readouts the gauge is showing almost nothing as well which plays with my mind and makes me refuel.

In other vehicles I have owned I have pushed it to zero and some and got into a regular habit of this and once put 55L in a 53K tank. The gauges in that car were dead on as I went about 2kms over the zero reading and ended up going for a walk!

The other thing to consider is that the tanks over time do fill up with crap/sediment and if we run the tanks to minimum then we end up picking all this up which most mechanics do not recommend. Then there is the 40 degree incline yoy try to traverse and I imagine you would need a few litres in the car to make sure you continue picking up fuel during the climb.

Just for interest on the last refill I let the fuel light come and distance to empty said 32k.. The car would only take 71ltrs leaving meaning that there was 13ltrs in the tank. Even at 13l/100k that would give me a distance to empty of 100k. Definitely different to my D3 which was alot more accurate.

This is what it looks like, on the 2.7 at least. Haven't seen the 3.0l

Very interested to read this thread - in fact, had been contemplating starting one on exactly this topic for a couple of days! This scenario has been bugging me for months. As with others, I have run my D4 down to about 30 km remaining on numerous occasions and then filled - to find that it won't take more than 67 - 70 litres! Even wobbling the car, waiting and adding more barely gets it over 70 liters - which leaves me thinking "well, where the heck is the remaining 13 litres or so??"

The other aspect that backs up this line of questioning is the "distance to empty" reading I get after I've "filled up" (but is it really full?) - usually comes up with between 630 and 660 km, which does not equate to 80 litres at somewhere between 10 and 11 litres per hundred! It's way under - at 10.5/100 that equates to just under 70 litres, so there's something weird going on here too. Given the need to squeeze maximum distance outta the beast in remote areas it seems that there's a good 100 km of extra range "lost" somewhere in all of this. Will be delighted if someone can clearly sort out what the issue is here.

Today I refilled to the brim again (liquid, not froth) with 67.8L after 670 kms, showing 9.0 L/100 kms (actual 10.1) and distance to empty 98 kms (9-10L). It doesn't add-up unless "empty" means when the low-fuel light appears with 5-8L left, although I doubt it would have gone another 100 kms before the light appeared. The gauge showed about 1/4 full but I still had over 250 kms to get home and didn't want to get too low.
