Ok I replaced the fuel pump and filter but still having trouble with it.
I've noticed now that it is a little jerky through the rev range but also I went out the yesterday and trying to get up steps I was having alot of trouble. I could get my front wheels up but then the car would stall after a little bit at first it was just a matter of rolling back down and cranking it for a little sometimes having to suck fuel up to the pump.
Thats a step I was trying to get up and after a couple of tries it wouldn't start but even on much smaller ones if it stalled on an incline I had to start from the bottem. A mate dragged me up onto a bit of flat ground but there was no fuel getting to the carb. Luckily I took my old fuel pump so I quickly swapped them and it seemed to be fine although we didn't try anything like that again.
