thanks for all the advice guys and sorry for the late reply.

I've made sure its not a vacuum in the fueltank thats causing all the problems ( had that problem before aswell )

Anyways so I replaced the pump and fuelfilter during the weekend and bam everything is running smoothly for the entire weekend until this morning on my way to work she stalls again. So I take another look under the bonnet and the first thing I see is my fuelfilter completly full of fuel weird, I take a look at the the float level and no fuel

So tonight i'll take of the fuel line off and put a couple of bars of pressure through it and see wat gets shot out the other end.
If thats not the problem is it possible for the float to get stuck at the top?
