Hi Dhanj, welcome to the forum,
Sorry don't have a definitive answer to your question, I have a 2004 QP but have not changed the relay or f1 pump.

Geoff,
Parts usually change at a certain assembly number rather than VIN, so you would need to check yours...it will be on a plate somewhere on your car...
for non USA QPs the number is inside the door...

Regards Enzo.

I also spoke to an Alfa supplier today who is not far from me (Veloces,

Dhanj,

If you are near Veloces then Bill McGraths aren't a million miles away from you, ±20 miles.

I've never had a Maserati for them to look after but have dealt with them with a Lancia once and know they have a great reputation for the Trident.

(I've no connection to them).

Thanks TridentTested,

Yes, I know of Bill McGraths and did speak to them. They still don't have the SD3 diagnostic equipment as yet though. For this job, if you're going to change the F1 pump I understand there is a need to bleed the system (checking fluids etc) and I think it probably wise to have the SD3 perform a test on the system after the F1 pump install and fluid check. Don't quote me on this as I am no expert but I understand that one of the checks/tests the SD3 can perform is to recalibrate/refamiliarise (don't know the technical term!) the gears for the electronic clutch on your semi-automatic gearbox (named Duo-Select in my case - my car is a 2004 QP) after installation of a new F1 pump and fluid bleed /check.

Anyway, QUICK UPDATE ON MY ISSUE: I had an indie in London fit the Alpha Selespeed pump as quoted in Loz's original post at the top of this thread (part number 51736315) to my 2004 QP. The indie also checked fluids and bled the system followed by a diagnostic check on their SD3. Of course the relay was changed too. I had never used this indie before so I watched them do it personally (for my own sanity you understand!). All in it cost about £650.

Have driven the car about 40 miles so far with the new pump and all seems well - the car is performing normally so, touch wood, the job was a good un (I will of course post again if I encounter any problems). For ref: the F1 pump on the early QP5's with Duo-Select is located just to the left of the gearbox at the rear of the car just before the lower part of the boot (not above the gearbox as I had originally feared (so you can get to it and replace without dropping the gearbox - just about - it was very tight in there!).

Many thanks to Loz for his original post (what a star!) and the follow ups from Enz, Parisien, etc.

I did take some pics. I will post if I can work out how to insert images on this forum. Give me a minute...

Cheers, Dhanj


ps - Further Update July 2012 - Driven car over a thousand miles now and F1 pump is still working fine so I think we can safely say the Alfa Selespeed pump works just fine on an early QP5 DuoSelect

Pics as promised - Install of Alpha 'Selespeed' pump on early QP5

Here's some pics as promised (sorry about the quality of the pics - my camera is pretty naff):

Apologies, I couldn't work out how to nestle the pics inside the message (I know, I'm useless!) so just hover your mouse over the pic to ascertain pic number and work out which is which.

pic 1879: Before the job - The old F1 pump located to left of gearbox as viewed from underside of car (front of car is to the right).

pic 1895: My old pump (from 2004 QP) taken out

pic 1891: New pump installed!

Also pic of new Alpha Selespeed pump

ps - This is obviously not intended as a 'how to guide to F1 pump replacement' - just showing location of the F1 pump on an early QP5 and confirming it can be replaced without dropping the gearbox.

Hi Dhanj,

Which London indie did you use for this?

Thanks,

Mark

There is another verry good guide by predator (user search his name) , which is the one i used.

If you unplug the solonoid wires to get better access as i did make sure they are connected bk firmly and maybe give them a little spray with electrical cleaner. otherwise a loose conection on these and you will get a beep-beep-beep and she will put herself bk in to neutral.

Not 100% sure if it fits but;

Eurospares are currently offering Ferrari F1 pumps for £295 new - Offer ends 30/01/16.

Ok just read this thread.

Need clarification as i am about to change the pump and relay on a QP5 2004 and want to be sure im fitting the updated items

Are there any up to date part number for these if so what would they be? Alfa parts will do.

Just to veer off. I fitted a Alfa 156 Alarm siren, same as the one on QP5 lol.

They are all the same.

You do have a choice to fit the upgraded Ferrari one which is about twice the size but other than that, just make sure the Alfa pump you buy is modern and not years old and and earlier build and they were prone to fail.

I doubt very much any of these old pumps are in circulation.
