Hey...Again

I might start a thread of "My mini problems"!!!

Broke down on M4 last night!!!! was out with my housemate at the time, just split with his mrs, came home and said "take me out for a spin in the beast,cheer me up", "sure" says I. 3 Hours later on slip road of J12 were singing classics at the topofour voices, ankle deep in mud. "This has been the worst day of my life"...

Anyway turns out its the fuel pump,I have been on minispeed looking at new pumps. The RAC man was on about electrical and mechanical pumps,and you can tell by the tick???? Anyway, mine ticks... so i think its electrical?

Which pump do I buy? Im looking for reliable and thats my main concern. Its a 1275cc Cooper S, it has twin tanks, I dont know if that makes a difference.

Personally I wouldn't buy anything from the source you mention, but that's just my personal opinion.
For normal fast road use the optimum pump, I've found is the Facet SS501 which retails at about £25-00 from Mini Spares. You also need the FPA906 pre-filter and rthe FPA903 Straight 1/4" union. Filter and Union should be around £5-00.
For a real 'fail-safe' installation install 2 off, separately wired in parallel under the rear seat with good quality 1/4" fuel hose. Then have one wired through the ignition and the other through a completely separate switch and fuse. You will also need 2 off 3-way 1/4" 'T' pieces.
That's what I have on my 1964 Cooper 'S' Rally Car and in over 12 years of competition I'm still on the same pumps and have never had a failure. You really don't need the expensive and fancy high-pressure pumps and with too much pressure the SU's can give trouble. The only other thing I use is an in-line adjustable pressure control valve.
This entire set-up could be done for about £60 +VAT and will last a very long time and be super-reliable.
I hope this helps.

Just a little tip, if I may.
When wiring, or re-wiring, for fuel pump(s), it's a good idea to wire the pumps through a couple of small and well hidden switches. Then if someone tries to steal the car, it may start and run for a few seconds on the residual petrol in the carbs, but after 10 seconds or so it'll just stop and the would-be thief won't know why. You can choose where to hide these switches, e.g, in the right-hand rear glove box under the ash tray, under the front shelf behind the small switch panel, in the front glove box, but around the back of it, behind the heater control panel, etc, etc. (other suggestions in a plain brown envelope, please!).
Anything to make the car a bit more secure can only be a good thing, and this is a no-cost measure, just a couple of switches and a bit of wire - the correct colour code, of course.

Thats what i`ve done,put the pump on a switch.Just remember to turn it off when you turn your car off,and turn it on when you drive off!
I made a right TIT off myself last summer there was a Ferrari at the house opposite and went out in the mini forgeting to turn the pump on and you guessed it i stalled in front of a croud and a Ferrari!weeping
Also the Sackless Moron who used to mot the mini,forgot to turn the pump off at the mot centre and knackered the pump!

What you should do it to run the wire to the 'secret' switch from the 'ignition-on' circuit then when you turn the ign off the pump will go off even if you forget the switch. The switch is really just an additional security device. Of course, if you have 2 secret switches for 2 pumps, you can still run from the ignition circuit, but via a different wire to make it all 'fail-safe'. After all, if the ignition circuit fails you just ain't going anywhere real soon!
