Right, seicento sporting 2001 mpi (1242 16v engine)
To try and cut a story short, had fuel tank changed last week as a free safety change, by Research Nuneaton as it had developed a leak.
Since the tank change if the tank is full upto around a third of fuel or more the car pulls as it should for the engine and no problems.
If tank is under around a third full of fuel the car pulses under full load, like the pump is struggling to pick up fuel. It did this mildly before it went in, but not until it was nearly out of fuel (to be expected).
I whipped the fuel pump out today and had a look and a clean up all is fine, and seems to be sat nice and low in the tank.
Could the pump be on the way out? seems odd as it runs fine when it has plenty of fuel in it and pulls well at any load.
Is there anything else to check for? any thoughts much appreciated.
