Help!...feels like my car is starving for fuel

I'm not doubting that it may be surge issues, but I'm just surprised as no one I know personally has had such issues, even on the track.
Having said that though, I was reading an old Motor mag, and the early 2000, bug-eyed, Imprezas (WRX included) has surging issues on spririted cornering in one direction even with half a tank. :roll:

Common on NA's even my Sunday only shopping trolley I've found at 7500rpm on the main straight at Lakeside
Coming up to the Start/Finish line, BIG surge if under 1/4 tank of fuel. Cal has the same problem!!!!

SandraD: try Penisula Sports Cars,Revolution Race Gear and speak to Brett, they actually raced one for a while.

Oh... ok then. There you go.
That confirms that I'm rubbish at the track. :mrgreen:

1. When fuel tank is 1/4 full
2. Making a left hand turn
3. The car faulters and looses power.
4. I have owned my mx5 for about 4 years and it has had this complaint since I purchased it
5. Has anyone come across this problem before?
6. Would anyone have a diagnosis?
Any advise is welcome
Kind regards

A common problem when the fuel pump is replaced
The new intake filter is different to the STD mazda one
1st pic shows the std mazda filter
imagine the table edge is the bottom of the tank

this one shows the filter supplyed with the walbro pump

Now the pump sits in a little sump in the tank
and this causes this to happen if you can get it in
And most of the time is wont.

also the filter faces the wrong way from the one that was pulled out
so the pump goes in the other way

also the filter faces the wrong way from the one that was pulled out
so the pump goes in the other way

when this happens the inlet to the pump via the filter can now suck air
when you go around a left hand corner (even at road speed)and causes
the fuel pressure to drop and the car starves for fuel.
