My fuel injection pump got very noisy so i fitted a new one, new pump is still noisy and top of fuel map is running lean. Any ideas please ( i have changed filter as well)

Try to insulate from vibrations..this maybe the cause of the noise and also fuel foaming making it lean...but to be honest your pump should not be at its limits in your car and should be capable of more fuel than required.

I had a similar,fault with my dohc inj engine.

On removal of the pick up and pump unit from the tank I found the pipe joint on the inlet side on the pump.

This still worked on a full tank as the inlet pipe was then under the fuel level.

I have also had a week mixture caused by a blocked inlet filter in the past.

As the level went down the pump started to cavitate.

As Nigel says the pump pick up system on yours is the most likely fault and is where I would start looking.

Think i have found it, i fitted a pump with a 12mm inlet but my filter is only 8mm. I have ordered a 12mm filter so this should sort the problem. Will let you all know after fitted
