Since it will be of some interest to you in the near future, my research (using a 94 Luxo Barge Pretender 3.9L V8 lighter version Vogue SE in heavy Brisbane traffic) has yielded the following averages.

Worst case scenario - approx 23 - 26L / 100 km's. In the morning's I sometimes never get over about 40km/h, stop - start for the 9km trip to South Bank.

On the long trips I have done down to Sydney etc this drops significantly to about 14 - 15L / 100km's

Make sure your vacuum advance is tickety boo as the city figure was worse before I got mine fixed.

The sound and feel makes it all worthwhile [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img] [img]style_emoticons/<#EMO_DIR#>/laugh.gif[/img]

The term 'ignition amplifier' threw me, I know it as an ignition module. Anyway, had mine sussed out and both the cam and ignition appear to be working properly but was advised to get it on a dyno and make sure that the ignition timing and tune is right.

Since my airflow meter is all over the shop I'm fitting a Wolf 3D computer so this should all be sorted out by that.

Just been away to Merimbula and back and got on average, while away 19.5 l/100km and the best I got was 16.9 l/100km... however normally driving to and from work everyday i get about 350km's (22/23 l/100km) out of a tank 8O

It does suck, but i do love the noise of the v8

Here is a good website for working out your full consumption figures.

Cheers, that IS a good tool [img]style_emoticons/<#EMO_DIR#>/smile.gif[/img]

no fuel should leak out from anywhere. there is no overflow on fuel systems.
sounds like a leak in the fuel filler neck. or one of the other hoses for the breathers.
you should get it fixed as it only needs a little spark.

also if its leaking out around corners it wont be helping your fuel consumption any.
