Default Which pump?

Hello!
I'm looking for a new fuel pump (75 V6 2.5 1st July 1999) just in case, to get it on the shelf.

BUT I'm puzzled at Rimmers because they give two different genuine Rover ones!

WFX100922KIT To SN-To 2D225075, CP Type-VIN at £218.40 inc UK VAT
WFX101471 From SN-From 2D225076, CP Type-VIN £354.00 inc UK VAT

I guess the former isn't complete: am I wrong?
Would it be a good move not to take the whole lot which is unfortunately far more expensive, it's a hassle to go there but the car is 23 year old ...


Thanks a lot for your help.

That's a whole lot of money for a "just in case" pump. DMGRS have the actual pumps at considerably less: https://www.dmgrs.co.uk/products/rov...d93fe6da&_ss=r

Keep well

Just had a similar dilemma. P.M. Trikey with your requirements and he can help too.

Hello Mike!
It's not actually 'just in case': as the engine is fed with full E85 (you know that well in Sweden) the pump is working longer than usual since 4 years (25% more fuel to send). I guess it has never been changed and it'll be 23 years on the 1st of July next...

Regarding Mat & Scott, I'd love to order from DMGRS but I've got a £50 voucher at Rimmers...
BTW my good mechanic (I can't rely on myself for such a job) is fussy & finicky and is never keen on swapping some bits without getting right all the used (or worned) ones which go together like washers and the like. Hence a full brand new item will do better than swapping a minima: IMHO it looks like swapping the belts without the pump and the pulley for example, am I wrong?

Hi Arnaud,

I know that I will fail but I urge you to stop worrying unnecessarily. Just because a component is 23 years old doesn't automatically make it unreliable, nor does a change in petrol specification. When my SD1 was built there was no such thing as unleaded in the UK or ethanol additives. The in-tank electric fuel pump gave no trouble whatsoever over 35 years.

Save your money for when something really fails.

Simon

Hello Simon man of good counsel,
It's not in my good nature to worry unnecessarily and I share your point of view according to the well known saying: if it ain't broken, don't fix it!

But a failing fuel pump is not uncommon at those ages, my E85 system is very demanding since 4 years and my £50 voucher is only worth until next november...

Indeed I'll not be that silly so that hoping a breakdown somewhere in the next 6 months!
But... I'm a cautious lad and don't want to be caught by surprise...
So what would be your best short list of likely failures?
Mind that i've already got on the shelf a reinforced thermostat housing from DMGRS (mine is very very slightly oozing since years...) and that my pride and joy is very cared for & serviced and in very good condition without any rust. Lots of different jobs have been already done (endless list!)...
Thanks.

It's impossible to say really, every car is different. I believe that the safest and most cost-effective approach is to buy what's necessary when a failure occurs. You can be sure that if you buy something "just in case" that it will stay on your garage shelf for fifteen years and you'll end up selling it on.

What you need there Arnaud is nothing more than a pack of 'O' rings (CDU 3858) and to set the serrated clips correctly on the straight pipe. Your reinforced housing is the result of a historic misdiagnosis that the seam splits because antifreeze residue collects on it. What actually happens is that the coolant sprays upwards from a flattened 'O' ring and hits the seam. Keep your existing housing because it's probably got the correct 88˚ thermostat inside which the current replacements don't seem to have.

All the best.

Simon

Hello Arnaud,

I think you remember that I ran my Vitesse on E85 for a while, or at least until the government raised the fuel tax. One of the modifications was adding a little two stroke oil to help the fuel pump, but perhaps the Rover pumps can handle ethanol better than my old Bosch one which was running at +20% pressure, uncertain as to the volume increase.

I’m a bit confused (happens often) as to what the Rimmer’s kit includes as it doesn’t seem to the 100% plug & play option you require.

At the end of the day, it’s your money and choice. Another consideration in your favour would be having a brand new rheostat, if that is included in the kit.

Keep well,

Mike

A mega thank to both of you for your wise advice.

I'll keep in mind that pair of "O rings" CDU 3858 Simon. I remember there was a controversy about it on the forum a while ago. I should admit it's a lot cheaper by a long chalk!
BTW my aim isn't to save money at any price but maintain my pride & joy in the best possible condition, you may have guessed so I bet!

BTW my voucher wasn't properly speaking a gift from Rimmers but a compensation because of a biased sketch (modified since) on their website with the consequence that some essential pieces (NLA everywhere) were missing in my parcel for my 214 cabby hood. Thanks to the well respected John Batchelor chairman of Rover 200 & 400 OC who intervened to twist the arm of Rimmers and a kind seller member of the club, the problem was solved.

I bought a UBP for my diesel as a spare from Rimmers , just in case job. Bad move by me. When I came to fit it at a one of our Nano Meets a couple of years ago, after having the pump for around 8/9 years in-the boot wrapped up in rag, fitted it and could not work out where the diesel leak was coming from. It was looked at by one of our experts at the Nano, and it was decided that it was leaking from the bottom of the pump because the metal at the bottom of the pump was to thin, or was porous Luckily another member had another spare ubp which was fitted and is still working. My advice, although it is a boring job to do, fit it when you get it, and save the one that you know is working ok...
