Well I fited a new fuel pump yesterday and having similar issues to what i had with the old fuel pump.
When you open the throttle to mor than half the car pitches and the engie splutters as though it is not getting enough fuel. If you lift off and then put your foot back down it goes again for a little while but then the problem comes back. I have fitted a new fuel filter before the pump as well. I have also noticed that the fuel pipe goes to a thinner pipe after the fuel pump to just before the second fuel filter prior to the carb, could this cause it?
Anyone got any ideas????
