Hi.
I need a new fuel pump, as old VDO pump died.
Found this on ebay
http://www.ebay.co.uk/itm/Fuel-Pump-for-Rover-75-1-8-1-8T-2-0-2-5-replaces-993784032-VDO-p3031-1FP-/181723805455?fits=Car+Make%3ARover%7CModel%3A75&hash=item2a4f95370f:g:01UAAOSwr81UNIEl

this pump fits to many other cars, if this site is correct:

I did all mesurements, and the dimensions is exactly the same, but what Bar pressure of fuel pump is correct for MG ZT-T 190?
Thx.

hmmm... 3.7?

If it is ok for a 2.5, it will be ok for a 190.

Aivis,

I can't see how either of the pumps you've listed will be suitable. They don't have an integral float for the fuel gauge, and they don't have the necessary internal connections with the fuel filter.

Why do you think that your current pump has failed?

How about THIS (http://www.ebay.co.uk/itm/Genuine-MG-Rover-Petrol-Fuel-Pump-for-75-ZT-2002-Onwards-1-8-2-0-2-5-WFX101471-/262125896963?hash=item3d07ebc503:g:VRAAAOSw5ZBWOJa K) not the cheapest I know, but it will work with the minimum of fuss ;)

Or, if you fancy chancing your arm with a second hand pump.......

It depends upon how much you like your car, and how reliable you'd like it to be.

If I was in Latvia with little or no specialist backup, I know what I'd be doing ;)

The 190 has the same pump as the 1.8 NASP, the 177, and 160 V6 John, the 1800 turbo has the same fuel pump as the V8 and is a higher output ;)

I'm assuming the OP has checked for FFS, or has bench tested his pump to find it has failed :shrug:

Still it's not the end of the world, what ever it happens to be, I'm sure he'll get it sorted one way or another :)

Simon, the pumps i have listed above is actual PUMP units. It comes out from that floating filter set. I have it on my desk in front of me right now and it looks exactly like those i have listed. You don't have to buy all set, if only your pump unit is dead - i suppose.
The old pump was tested outside the car, conclusion - dead!

Thx Brian, i don't need whole set, but info on pumps across the models is useful.
I think i'll go with new pump unit and will hope that it will be capable to achieve correct pressure for 190.

Interesting that the 1.8T and V8 share the same pump, yet the V6 has the lower output item!

Its about pressure, not volume. The turbo runs higher pressure to maintain a differential over the manifold pressure. Not sure about the v8, i guess the yank just needs more pressure.
At least this is how i understand it, please correct me if i'm wrong.

MG Rover fuel pump data is as follows:

K1.8: 0.65 litres/min. at 3 bar.
K1.8 Turbo: 1.23 litres/min. at 4.5 bar.
KV6: 3.5 bar, flow rate not given.

I find it strange that MGR would fit a higher rated pump to a car with an engine that produces 160 bhp, than to one that has an engine producing 190 bhp (especially under project drive) but I will bow to Brian's superior knowledge! :bowdown:

I fitted a normal 1.8 pump to Denise's 1.8T and the car performs perfectly. I don't know the reasons behind the differing pumps but, not many cars are pushed to the limit as far as pump demand goes.

Tried to resist answering this but couldnt.
He use of higher pressure for the v8 has nothing to do with 8 injectors. it's obvious the yanks designed the system for the higher pressure, so mgr had to follow suit. More injectors do not need more pressure, just more flow.
As for few turbo cars being pushed to their limits, maximum torque will correspond to maximum boost, not neccassarily at 6000 rpm, therefore at full throttle, 4500 rpm or so - ( go on, someonetell us where the k turbo peak torque is?), the fuel pressure needs to be above the manifold pressure, sufficient to deliver the required amount.
Each "squirt" will be at maximum duration. As the revs rise, these will tend to drop, actually.

2,100 rpm Huw. :drool4:

So, i have bought and car service installed, new fuel pump made by Meat & Doria (strangest part manufacturers name, whos parts i have bought :) ). This fuel pump was in exact dimensions as old one and output pressure was mentioned 3 Bar (not on the pump unit or packing). But car runs fine (been in it 5 mins now, will need testing on higher revs). Anyway, looks like it will work just fine.
Also this pump unit fits Audi A2, Seat Leon, etc. and cost 45 Euros.
