Fuel surge

[philo]

Experienced this through fast right hand bends when tank reached half,I popped to petrol station and filled up,my sport Evo used to do this...I would have thought bmw would have sorted this by now....

Anyone else experienced this? Not too bothered as wont be on track too much... I think

Yep typically below 1/4 tank, long right handers like Coppice at Donny, Stavelot at Spa, Old Sears at Snetterton.


Can fix it with dual pick ups or twin pumps apparently.

Thanks shimmy,I thought half tank was a bit bad?? Both corners were not flowing quite aggressive turn in for both,if its not a fix with original parts its just going to have to stay like that,pity as I didn't expect that to happen in the greatest m3 ever lol

I experienced this the other month on the National circuit at Silverstone (after Woodcotes - the fast sweeper before the pit straight). Like Shimmy it was only ever when it dropped below a quarter of a tank.

Obviously having read about it on here, I instantly new what it was, so just now make sure it doesn't drop below that level.

I've heard of some guys with probs at half a tank just depends where your pick up is lying I guess.
