I think I may have solved it. Well, not solved it, but identified it.
I bodged the exhaust today just to stop the blow - I did another test, the cardiff to barry run, and I worked out the MPG to be 19.2 instead of about 16.5. MID was reading 26.4, which is about what I would expect to get on that run.
So that's a couple of MPG improvement. After I Filled it back to the top again, and got back... I noticed a puddle behind the back wheel. So I climbed under the car with the torch to investigate, and it was pretty clear by the smell that the puddle was petrol.
Looking under the car, I could see petrol, running ALL down the front of the tank, and dripping onto the floor at quite a hefty rate. I reckon at least 1 litre came out since it's been parked.
I'd like to sort the problem though, any ideas? And... silly question... I take it this is why I've been "using" so much petrol after filling the tank!!

If you want to replace the tank, Ive got one already removed, only needs a cap ;)

So MID is reading MPG you would expect, but petrol tank emptying quicker? I think MID is probably fairly accurate...
Dunno about leak, you just have to locate. Possible hose between tank and fuel filter?
-
In my experience, MID always reads about 2 too generous, giving me an MPG of 24.3, which is exactly what I would expect. The engine is actually running lovely, and since exhaust bodge doesn't feel rich at all, so I reckon this leak is to blame.
I could just half fill the tank ;D

Depends if its a hole in tank, or hole in pipes...
-
First off.....remove the inspection cover in the boot area (under the carpet) and check the level plate seal....
Thought the exhaust might be buggering up the mixture.....
-
Cheers matey, I'll do that in the morning....
-
Your wasting petrol by filling the tank right to the top anyway, better to half fill it, ur not carrying all that unnecceary wieght around with u then!
-
Carrying an additional 30 litres for such a powerful car would make a negligable difference and probably not noticable for fuel economy.
There is a differnent issue causing the excissive need for filling up
It's most likely the leak described in this thread.
-
As Marks says, check under the inspection cover in the boot, I had exactly the same problem, turned out to be leaking from the plate which carries the fuel level sensor etc, just appeared to be loose but a good clean up won't do it any harm.
-
Isn't there an overfill pressure release valve thingy somewhere near the top perhaps it knackered just a thought as mine does exactly the same when full up, so I tend not to fill it right to top lately.
Also noticed I loose petrol if its parked on a slant so try avoiding this aswell, not ideal but works till I can get it sorted.
-
i think i heard of this kind of leak before on the other site, only affected it when brim full.
Try another test.... get the tank level to 1/4 then give it a run and see what the mpg is and check for leaks! :y
