so gonna take deep look in to my car this coming weekend to see why its not getting the right melt of fuel guessing there's some kind of blockish in the lines or the pumps falling I took a look in the engine bay to have a look at the fuel filter and its not as clean as it could be and not a lot of fuel sat it so guessing there's a blockish in the lines somewhere or pumps not working probably if anyone has had this similar issue be grateful if you could help thanks Dan

I've had to change an M10 pump before - mine was struggling at high speeds to supply enough fuel. The rubber diaphragm inside them wears out. Change the inline filter too, they cost like a quid.

There is also a filter in the bottom of the fuel level sender unit in the tank.
