Poor acceleration with less than a quarter tank of gas

[JimmyJames1]

I'm having really poor acceleration when I have less than a quarter tank of gas in the car. I'm running a Walbro fuel pump with stock turbo and fuel on a S13 SR20. Has anyone ever dealt with anything like this?

I have heard of this,dosnt happen to my 240 with a walbro,But there was a thread about it not to long ago.So your not the only one.

Can't find the thread, I searched but nothing came up. . .

Maybe look into replacing the Walbro pump with the more reliable Denso Sard one.....I remember seeing the thread about this and if I remember it correctly, the consenus was to not let your gas go below a 1/4 when running the walbro. Not sure why exactly walbro's have this problem.

Found the answer! I'm running an S13 pump kit on an S14. This places the fuel pickup sock in the wrong direction. I've found a site that offers a kit to correct this and I'm ordering it today.
