It would be worth changing the fuel filter first, p/n - WJN101190
if it is the pump, the p/n is WFX100670

Dieters EPC has most part numbers - http://www.mgfcar.de/epc/2.htm

Brown & Gammons or Rimmer Bros will be your best bet for supply

 

Another alternative would be a second hand one as the fuel pumps rarely fail..

I would suggest trying Victoria at the MGF Centre if you want to go down this route. It could save you a lot of money..

Mike Satur has an 'uprated' version... although I am not sure if you really need that one.

First of all I would check the electrical connection on top of the pump (easy DIY), as there could be a malfunction in the connector (sparks making the contacts dirty and have part of the connector melted/destroyed).

In that case you don't need a fuel pump, but you'll need (a part of) the ciring loom.

 

Fuel Pump problems seeking help

Hi Guys! Decided to take your advise and DIY( Need your constant guidance though!). Got the car towed back from the service station and with the turn of the key the car started.

Eng RPM fluctuating btwn 600 - 1000 and settling to abt 800 and jerky. Still suspect the fuel pump?? Could it be the fuel tank with dirt in it as the last owner had it tucked away for quite some time???

Wl check the electric as sugg by ErikB.

Pls advise if I need to change any more parts to get it running good! I plan to order the parts at one go in order to save on freight charges.

Pls feel freee to suggest anything as I am in dire straits to get this beauty running again.

Coolant, eng oil, sparks are all new.

Planning to change :-
1) Fuel pump, filter and any suggs ??

Tks ErikB, My old flame-Stu/MGOT and Petevick for your help. Greatly appreciated and hope you give me more suggestions!

Tks and Bong Anoite( good night in this part of the world)

Change the fuel filter first, its cheap to buy and very easy to change yourself, simply unbolts from the fuel pipes. I think there is a guide on here if you do a little search.

If that doesn't resolve it also check the air filter is ok.

If neither of these do the trick I would suggest some fuel injector cleaner in the tank and run it for a whilst see how it goes.

From there you could start considering the fuel pump as a potential cause.

 

Good news about the DIY desission

Have you had a look at the tips of the spark plugs ? They could tell you more about the mixture the engine is using.

The fuel pump feeds the fuel rail, which needs aprox. 3 bar, with a feed of aprox. 2 litres per minute. The amount of fuel that isn't used by the injectors or by the pressure regulator to maintain the 3bar, is returned to the fuel tank. It could be an idea to have a look at:
a) the amount delivered by the pump (2 litres per minute is quite a lot), so how much could the pump deliver after 30s ? (disconnect the fuel filter, have the fuel captured in a container during the first 30s with key in position 2)
b) the amount that returns to the tank

After all this, you must be able to tell if the pump is in a good working condition or not.

Please only do these things if you're feeling comfortable with it. Afterall it is fuel !!

 

Heres how easy it is to change fuel filter, and it could cost you 10 pounds instead fo 500!!

Worth doing first
