Sounds like I'm doing the right thing then. I have noticed the underbonnet pump get a lot louder, but I guess that is just a symtom of its in tank buddy giving up....

Well, PUG pump on order (406 style), due about 3:00 pm. So will get the old one out after lunch and get ready for the change over. Heres hoping it turns up on time !!

Just a quick post to say that all was no straight forward with the Pug motor change. I actually went for the 406 pump, but I'm not sure if what was delivered was actually right.

For one thing, the diameter of the pump / motor body was at least a couple of mm less than the Rover pump - although it did end up fairly well jammed in place.

It also isnt clear in the "how to" as to what happens to the black strainer on the bottom. It reads as though you re-fit the nice black one that came with the original. But, this simply didnt fit to the bottom of the Pug pump I had, so I had to fit the plastic rubbishy thing that came with the new one. (Fortunately I didnt break it dissasembling it)

But other than that, the "how to" is very very good. I also didnt take D2 out. Instead I cut the tube away from the pump, leaving about a third of the transparent bit to use again. To re-fit, I found it was far too stiff to push onto the spigot, so I boiled a cup of water and dunked the end in for 30 secs or so - that went well, especially as I didnt spill it into the tank

, and a small jub clip is now holding it in place.

I'll attempt to post some pics I took, but will have to wait until next week as I am really busy till them. It took me about 2.75 hours to do

I am now just wondering how careful I need to be when running low on fuel, as I doubt that the pump is sucking at as a point as low as before.

I'll see what paperwork came with the new pump, but it was definitley a Bosch. Is that what others got ? - it did look from a distance identical to the how too.

So thanks to all for the help (incl getting the back seat out). I am at least now up and running with no funny noises coming from the front.

Just for completeness, and to help out anyone with similar symptoms.

Before I changed the in-tank pump, the car needed the thud on the under bonnet pump approx 1 out of three starting attempts. After the pug pump replacement it is failing about once in 12 attempts.

So I am guessing that the underbonnet one is on the blink too. So I guess that s one for the weekend. Anyone got any advice on the best source / way to do the job. (Seems straightforward from a distance, and no "how to", so it must be obvious.

I just hope that is isnt the in-tank pump failing to deliver delivering the required pressure.

Try and find Jules thread on the under bonnet pump. He ripped one to bits to see where it failed.........they basically wear out.

Frobs · 2nd April 2008, 22:41

Thanks Greeners.
I struggle with searching the forums sometimes. Perhaps there should be a "how to".

Anyway, managed to track down the thread and am currently receiving emails from partsgateway - nice one - love this site ""

Very latest is that now the car will not start at all. The underbonnet pump now makes no noise when ignition is on, so I guess it is goosed.

Good job I started looking for parts through partsgateway - although it says everyone is out of stock - other than Roverbreakers at £146-00

Yikes !!

Anyone got any better ideas

Try ECP (ECP2004 on ebay)

Frobs · 3rd April 2008, 17:38

Thanks Greeners,
Best price was £146 inc VAT and delivery. So I talked to our local parts place, and they matched the price ( List was £158+VAT) so I think I got a good deal. I jest thought they were a bit cheaper.

Looks pretty straightforward to change the pump. Any special tips from anyone ?

Also, I havent disconnected / reconnected the battery before. Is there anything that I need to know about that (ie alarms, ECU, BCU etc )

Cheers

Just make sure if you've got satnav, the red light is off before you disconnect the battery, and that you've got the radio code.

I'm pretty sure its an easy change, but no doubt someoen who's don it will give you some pointers....
