Hi guys

My 1967 Deluxe decided to break down at Erina Fair on the Central Coast on Friday evening.... (For those of you who don't know this place, there are better places to spend your Friday evening e.g. at home, with a beer in hand).

I noticed when I left work that after getting the car up to 3rd and 4th gear it would lose power and feel as if it were engine braking even with my foot down.

I managed to crawl it into a car park, do my grocery shopping and when I started the car again it cut out after about 30 seconds. I then tried starting it again and again only for it to last a few seconds at a time before cutting out. After that it just would not start at all.

I noticed that the noise of the fuel pump had completely gone by this point (the noise when ignition is turned). This and my technically minded friend on the phone led me to believe the fuel pump had done one.

If it is indeed the fuel pump, how easy a job am I to expect replacing it? Is there anything in particular I should be aware of? I have recently moved and haven't pulled out my Haynes manual from a box amongst many yet. Minisport seem to have fuel pumps from about $100 - $250, is there anything specific I should be looking for?

Thanks guys, any help would be greatly appreciated.

First thing to do is to bench test it. Take the pump off and run it with a battery - if it starts up, it may be a connection somewhere.

I had an issue with my fuel pump, and I dismantled it and found a loose solder job inside. Re-soldered it and it's been running fine since. So just because it's stopped working doesn't necessarily mean a new pump - they can be fixed.

For an average mini I'm not aware of any special requirements. You should just need a standard pressure pump (SU carbs only need a few PSI), like the SU's fuel pumps you can find at minisport etc.

If it's got the old ticker pump in the back you could do one of a few thengs. By a crap electronic replacement one from Supercheap, get a genuine SU one from maybe Midel or the like, about $225. Or, after checking back of engine for plate, fit mechanical one on engine.

Just to confirm...we are talking about a electric pump not the mechanical one on the back of the engine?
If it's the electric option (after market?) where is it mounted? in the boot or under the boot on the subframe?
The only real things I'd check are all the rubber hoses and clamps making sure they're all in good condition. Is the pump rubber mounted? if not maybe upgrade time, it'll reduce operation noise. Finally make sure their is a (new) filter between the fuel tank and pump, if sh!t gets in the pump it'll die again much sooner.

Hi Guys

Thanks for your responses. In theory the removal of the fuel pump was easy, however whoever installed it (previous owner) did so in the strangest place.... got there in the end though.

It was an after market pump that was bolted to the subframe in a way which wouldn't allow me to reach the nut to hold whilst I undid the bolt.

Lucklity I have a friend with abnormally long fingers who was able to assist.

I bought a genuine SU pump which works (tested prior to use) and it will be installed this week. I'll let you know how the first run goes.

Thanks

When u test it make sure u test it buy pumping fuel thru it not just turning it on

Success!

Fitted the new pump early on Saturday morning and all is working nicely.

There were holes already on the subframe that were exactly the same size, and distance apart as the bracket for the new pump required. I am guessing that it used to have an SU pump once upon a time but the cheap one that broke on me replaced it.

The only unforeseen issue I faced was that the wires used for the old pump were way to short for the new one, this was rectified with pliers and plenty of electrical tape easily

As well as changing the pump, I also changed the hoses and fitted a new fuel filter. The old one looked horrible so rather than pumping a load of crap into the new pump, I thought squeaky clean everything would be the trick.

One thing I will advise any novice mechanics (like me) is that the pump I removed ticked all the time when the ignition was turned and ticked less often when the engine was started (this indicated to me that the thing was working, and as per my original post, indicated to me that it was in fact the pump that was broken when it stopped ticking), anyway, this new pump only ticks every 5 - 8 seconds (sometimes less). After a bit of research, I discovered that this is normal for this type of fuel pump (SU) and it will tick more frequently when it needs more fuel.

I'm sure most people will have known this already but for mechanical noobs like me, this information could prove useful.

Anyway, I have driven the car everyday since and it is awesome. I missed the old girl.

Thanks for everyone's help on this.

Andy
