240SX Ka24DE S13 - Fuel problem

[Gogach]

Fuel problem - when gas is less than 1/4 Full, car wont go above 4000rpm on full throtle, or go uphill, or do hard turns - because it takes off power. Car sounds loud - air is pumping obviusly, but there is no power, more to be precise, car is deacelerating.

Changed fuel pump, going to change fuel filter but, if all those things were problem, why is this happening only when there is less than 20 liter of gas left only?

When you changed the fuel pump, was the sock in good condition? And yes, change your fuel filter. Get the one meant for the Z32, it supposedly fits and will be less restrictive. Do a search on fuel filters to be sure thats the one first, but I'm pretty sure. If all that doesn't work, I dunno...good luck.

Fuel pump was brand new Walbro, 255 LPH. I have a feeling like fuel pump isnt reaching a bottom of gas storage, so, in hard turning or uphill, it can't reach fuel.. This week I'm changing fuel filter.

So, few days ago, I have changed fuel filter, the same thing is happening. After changing fuel pump, fuel pump filter, fuel filter under the hood, stil the same thing... What to check next?

I have almost the same symptom with my ca18det this weekend with 1/4 tank Left . This was the first time the car was doing that and now it run nice.
