Not sure when Andy (trikey) will be back today as he was staying over in Hull last night after the meet but no doubt he will see this soon.

Ahh, say no more. The recovery mechanic was, no doubt, basing his diagnosis on the diesel engined Rover 75 where fuel pump failure is well known. However this particular fault does not afflict the petrol engined models.

We've all had to swallow that bitter pill at some time in our lives Saul so I sympathise.

Trikey has just broken a V6 so you might be in luck.

Once you've got back to square one, take Roverbarmy's advice on checking that the filter canister is tightly assembled. Do not dismantle it or you'll land yourself in more trouble. Simply ensure that the two parts are screwed together firmly and fit the preventative clip.

Saul, your car is on the cusp of being unaffected by fuel filter module separation.

A simple check to save any further dismantling is easy, the filter module is located in the opposite side of the tank to the pump.

When you look at the top of the module, if there is a loop on the top, it is the earlier type, and wont be affected.



The later type which has a "lattice" type casting to the top is the type that has a filter module which can unscrew, allowing the fuel to be discharged into the nearside of the tank saddle, allowing the offside where the suction side of the pump is to run dry.



In the first picture, the tank neck seal can be clearly seen as being located on the filter module, this diablo shaped seal must be fitted to the tank neck orifice,, and not be left in place on the pump body, or it will prove impossible to refit the pump module to the tank.

You should be able to cannibalise the sender unit from your original pump module in order that the replacement can be repaired.

Best of luck

I have the earlier type filter and the filter is removable and has 3 o rings. I am having problems with the fuel going back to the pump side. I think

any advice is appreciated, Thanks

I had same problem, although a couple of times during past weeks i noticed a slight hesitation. Whilst parked on my drive after a 10 mile drive i went to it 6 hours later only to find it wouldnt start.RAC arrived says"There are 2 tanks on the car so he put in £30 of fuel rocked the car side to side still no good.Took to a RAC garage.Problem need a new fuel pump.

Terry,

KV6 fuel pumps rarely fail. I urge you to check the following, which will present similar symptoms, before parting with a lot of money.

• Fuel filter separation, if you have the later design.
• Crankshaft sensor signal missing.
• Camshaft sensor failure.

Note that the OP renewed his fuel pump without success.
