Fuel pump replacement

Post by **sowden** » Sat Dec 20, 2008 7:44 pm

Hi all,

my petrol pump points keep sticking. Every journey I now make is punctuated by at least 2 stoppages - 4 times every day in total!

Its getting a bit wearing, and I wonder if anyone has experience of these:

A Quinton Hazell item allegedly - are they OK? I've heard people running down the German ones (dont know if these are the same).

Cheers,

Russ

That looks very much like the German type which are often sold via QH. Often they pack up long before you have to worry about the points being worn out.

A set of points for the long lasting SU pump may be a better opton, but the choice is yours.

It looks lioke a Hardi pump. The Hardi pump is electronic, so has no points. They normally sell for about £65.00

the Hardi pump that failed on me had points - they are sold as 'electronic'

Just clean the points in the pump you have !

Hi all,

my pump failed alltogether on me today. I cleaned the points with emery, then gave a dry wipe over. No change. Then cleaned with Cellulose thinners. Just now, to try and get it going, I pulled folded wet and dry (1200) though the points. Still nothing unless you hit the pump and even then just one blip.

How long do electronic ones last? Is it weeks, months or years, anyone?

If you decide to get a new pump, I'd also buy a set of points and fix the old pump so you can carry it as a spare.

Fitted a Hardi 5 years ago. No problems so far.

my su pump is nearly forty years old and still working

As is mine - and my spare. The points in your pump must need adjusting now - read all about it in the Manual!

Chaps,

I remembered in the midst of this problem why I run a Minor...so you can fix them when they break, without having to plug them into a computer or throw the old part away after replacing it.

I took the pump off, and had a good look at the points. No wonder a light scrape with emery didnt work, they were as pitted as buggery.

I took the points assembly to bits and emeried the points to near flat, and reassembled. Test drive has showed no problems.

Thanks for your support!

All the best,

Russ

you really would be better off getting some new points - can be done in less than half an hour with the pump on the bench...

Well done Russ - that pump will be good for another 40 years now. If you put a radio suppressor on the electrical lead it helps to cut down arcing - and keps the points in better order.
Just a thought - had you recently changed the polarity of the car ?

I agree with Ray that it would be sensible to fit new points.

Guys,

why is it better to replace the points rather than just file them down? Can I ask, will it help prevent the pump from working intermittently?

Cheers,

Russ

Because if they've been filed down there might not be much life left in them, whereas a new set should last for tens of thousands of miles.

Hi all, it's also a good idea to install a new diaphragm as unleaded seems to degrade rubber parts more quickly.If you put in diaphragm and points you basically have a new pump.

I would also say that the pump is a Hardi pump branded as QH. I installed one over a year ago and never had a problem since. The only thing I find is that they are noisy and in my case, the bulkhead and battery box act as an amplifier.
The solution is to use industrial M6 anti-vibration mounts-see photo. We use these all the time to mount engines on large model aircraft to reduce vibration in the fuselage-it works a treat. The Hardi pump is quite a common replacement here in Germany.

Hiya guys

just an update on this thread:
ended up fitting a new pump, as I didnt have the time to faff with the old one. I've had it on about a couple of weeks now. Its peachy, and the peace of mind is nice. It is a bit noiser than the old one, but to me this is a benefit as you know its working (always liked that feature of the fuel pump, ever since I got my first mog)! Adds a dash of colour under the bonnet too (whether this is a good or a bad thing is down to taste eh)

You can pay up to £70 for these, but mine was £40.

I have taken posted advice and bought some new points and in due course, I will repair my old pump and keep it as a spare.
