ok have typeRA witch revs fine to 7800rpm ,running around 350bhp
but when get down to quarter of tank of fuel ,when on trackday's when pushing car hard through tight turns ,
i start to get fuel serge(fuel cut) at around 6300-6500 rpm
anyway of fixing this without takeing out a bank lone

i dont say put more fuel in car quarter of tank is about 20-25 liters

 

JDM's have a 60 litre tank - so a true 1/4 is 15 litres.

Just regard 1/4 on the gauge as 'empty' - simple!

It means you'll never use that last 1/4 of a tank's worth (although it'll always be replaced by new fuel, as the pick-up is obviously at the bottom). But if you do let it go below that level, then you could end up with a melted engine when hooning round corners (even more at risk when doing track work!)...

 

take sender out of tank and bend the arm so the gauge reads empty when actually 1/4 tank.

 

Hey. I like the idea of that, as it's still tempting to carry on driving when it gets to a 1/4 anyway, through procrastination, laziness, lack of cash, etc., etc...

Top tip that.

 

Obvious answer to that is don't run a quart tank on track days.. Alternatively you could go for swirl pot setup, wouldn't cost that much, just need another pump, a swirl pot and some time etc..

I remember reading another post about this some time ago, there was a mod for it or a different type of STI pump if i remember. Do a search you may come up with something.
