Fuel pump

[Taximan]

Can anyone tell me if they have had an issue with there fuel pump in the tank like mine.

My car seems to struggle to drive like all 4 brake calipers are stuck on when a have more than a 1/4 of a tank of deisel in but anything under a 1/4 of a tank she flys along like there's no stopping her.

So am wondering could it be the fuel pump in the tank struggling to provide enough fuel if it's got to much in for the pump to send it out to supply the engine thanks.

You've probably already told us this somewhere else but can you tell us whether your car does actually have an in-tank pump or it's one of the ones with a squeezy bulb in the engine bay?

I must admit that, even so, I'm struggling to come up with an explanation for this.

Front disks grabbing ?? a well know @fault@ with the calipers on the C5 _01-08 cars

If there was a fuel system fault the engine management light would come on. Just wondering if the rear load sensor is somehow applying the rear brakes with a heavier fuel load?

Thanks for the reply

It has got a pump in the tank.

You could be right about the front calipers but need descent weather to remove and clean.

As for as the rear sensor goes a don't have a clue about would a need diagnostics to tell me about the over wait sensor.

Thanks
