MG ZR ZS ZT Technical - ZT-T fuel leak!

I had found my car would not start, found it was the in tank pump. I sorted this and went to fill the car up. When it got to top fuel started pouring which looked like from top of fuel tank. Does anyone know for sure it is the tank before I replace. Was leaking at the back by the rear wheel. Help!

Unless it's rotted through (surely not) isn't it more likely to be a gasket leak where the pump or pipes go in?
Paul Hunt

Not sure it got down to 3/4 of a tank and leak stopped.

The in tank pump is on passenger side and leak is on drivers side. I had pump out at weekend. So should not be that. If I get tank replaced will that solve problem?
Damian

It could be the filler tube that's rotted. The other possibility is that you have not correctly reseated the module, in which case you will probably have fuel over the rear carpet.

The in-tank pump is not on the passenger side, unless you are driving a left-hand drive car.

You have not said what engine you have in the car, or what age the car is. If the problem was with the unit on the left hand side of the car (i.e. the filter unit) then I guess your car is petrol. In which case you may need the clip as specified in the MG Rover technical bulletin.

It is an 03 2.5 rh drive. The reason I said pump was om left as had aa out on Sunday and he took it out and it was a plastic thing which was White and looked like a can of Beans in size. It had came apart and he scewed back and put back saying I needed a new seal as it expanded. He opened other side and said that was the thing to measure how much fuel was in it. Now I'm not a mechanic so really need sound advice before a garage rips me off.

The fuel tank has two holes in the top of it. The fuel pump on all Rover 75s & ZTs is on the right hand side (looking from rear of the car). On petrol cars there is a fuel filter module on the left hand side, which can twist apart on some cars. There is an orange plastic clip (part number WJC000230) that can be fitted to these to stop them twisting apart. The equivalent module on the diesels do not suffer from the same problem.

We've had another 75/ZT in this week with fuel leaking from the tank. The car had been recovered by the RAC to us after it had previously been recovered for a failed fuel pump.

This is now the second diesel car that we've had in a couple of months that has had a missing seal from the passenger side module. It is our belief that this module is being removed (unnecessarily) by the emergency breakdown services and being replaced without the seal.

*Would* the RAC (or any other recovery organisation) go into things in that much detail by the roadside? Or would they as you say simply recover it to a 3rd-party workshop where *they* may be leaving this seal off? In which case the beef is with the workshop, not the emergency breakdown services. In either event you have grounds for making a claim against whoever did the work.
Paul Hunt

Yes, both the AA and RAC will attempt to fix a fuel pump problem on a Rover 75/ZT at the roadside. However, most of the recovery guys don't seem to know the difference between the petrol and diesel cars.

I now keep spare fuel pump/module seals in stock.
