Hans,
   Good on you for 50 years on the pump.  Into my 1972 GT, tomorrow, goes it=
s third, as the second failed last week, at ten years and 25,000 miles.  I h=
ave never been successful with replacing diaphragm and points. Well, success=
ful in that the pumps did not leak, but they would not pump. =20
    Installed in my GT is an auxiliary pump, wired to an unused rocker switc=
h on the console. When the engine falters, moving the switch brings the auxi=
liary pump into service and engine runs well again. =20
   Running on the auxiliary pump, we drove in the CT Triumph Club=E2=80=99s B=
ritish Reliability Run. 906 miles were added to my odometer.  All cars trave=
lled reliably and successfully, except for one that had a Weber carb, when i=
ts throttle return spring broke.=20

You need to check the electrical connections first, right on the 12v and =

Thanks Dave. 

The temp pump was a box shaped electrical pump. Unlike the original pump it
always made a lot of clicks and indeed was pretty noisy. 

As I have plenty of old inner tubes left of my classic mopeds, it is easy to
make a sound insulation solution. 

BTW I'm located in the Netherlands, so I think I'll try to find a local
supplier of such pumps.

For what pumping capacity should I look for?

Yes, Moss is pretty expensive and the electronic pump and the conversion set
are n/a currently.

Cheers,

Hans

You will get lots of answers.  Unless you are an originality nut, there is
NO reason to go back to the old pump.  If you want to overpay, the
electronic pump from moss is the way to go.

If not, and you want rock solid reliability, go with a Facet, AND carry a
spare.  Wire it with "clips" so that you can remove it and replace it
without doing a bunch of splicing and cutting.  I've attached a receipt for
one.  I suspect you are in the UK so you probably won't want to order from
this supplier!

Also - these are a bit noisy so put a pad between it and the car

Subject: [Mgs] Fuel pump failure

Dear listers,

The GT recently had been MOT tested (the very final one, as next year the
car will be 50 years old and the MOT test is compulsory anymore).

After a visit at a nice terrace at a lake with some drinks, I tried to start
the GT again, but the starter cranked without success.

As I had no spare pump with me, I had to call the road services, who made a
temp fix by adding an extra pump in series.

Convert to electronic points? - Is in backorder @ Moss now. 

Any experiences?

Thanks in advance.

Cheers,

Hans

Bob,

Not fully true. When restoring the GT in the period of 1990 =E2=80=93 2000,=
 I took the pump apart and polished the contact points shing bright. 

I think the car made some 15,000 miles after it came onto the road again in=
 2000.

15,000 miles for me is not really reliable, certainly not compared with mod=
ern cars. I once drove an Audi A6 model 2000, which car never had a pump fa=
ilure over 343,000 kilometers =3D 214,000 miles.

Cheers,

Hans

Hans,

   Good on you for 50 years on the pump.  Into my 1972 GT, tomorrow, goes i=
ts third, as the second failed last week, at ten years and 25,000 miles.  I=
 have never been successful with replacing diaphragm and points. Well, succ=
essful in that the pumps did not leak, but they would not pump.  

    Installed in my GT is an auxiliary pump, wired to an unused rocker swit=
ch on the console. When the engine falters, moving the switch brings the au=
xiliary pump into service and engine runs well again.  

   Running on the auxiliary pump, we drove in the CT Triumph Club=E2=80=99s=
 British Reliability Run. 906 miles were added to my odometer.  All cars tr=
avelled reliably and successfully, except for one that had a Weber carb, wh=
en its throttle return spring broke. 

Bob

Dear listers,

After a visit at a nice terrace at a lake with some drinks, I tried to star=
t the GT again, but the starter cranked without success.

Any experiences?

Thanks in advance.

Cheers,

Hans

Hans, one thing to check is the ground in the back center of the boot. 
I've had those get a little loose and cause the fuel pump to become 
intermittent. It can also cause some odd light symptoms that you 
probably would not see from inside. I tend to stick with the points.

Hans,

I replaced my SU pump with a Facet, which sounds a lot like what you 
have in your car now. I tried replacing the points in the SU pump, but 
the diaphragm had gotten so stiff with age that it wouldn't pump any 
more. The facet is noisy as hell and a mount with lots of Sorbothane 
would be a very good thing, but it does work reliably. Be sure the one 
you have is a low pressure (3 lb) variety. There are higher pressure 
models that look just like the low pressure ones, and will happily 
overflow your carburetters.

I was recently wondering if some kind of gear pump would be quieter. 
Don't know if there are any suitable ones out there that wouldn't 
require a fuel pressure regulator.

Cheers,
Dave

Hi Steve,

The pump is out. 
I checked the wiring before taking it out.
The ground wire goes in the same loom as the 12V feed (White). 
I measured the ground connector, which is zero ohms, so nothing wrong there.
I'll order new points adjust these and clean everything thoroughly.
I also can test it offline of course. I have separate a battery available.

Cheers,
Hans

I realise it is out now but you have to measure voltage with the wiring 
connected and the component powered to see if you have bad connections or 
not.

Ohms is very unreliable when looking for a bad connection as by its very 
nature it is likely to be variable, and will vary with the level of current 
and voltage being applied.  An ohmmeter supplies a very low level of both. 
If you measure 12v on the component terminals then the supply is good and 
the component is faulty.  But if you see less than 12v the connections are 
bad.

Hans,

The ohmmeter doesn't draw enough current through the ground connection 
to be a reliable indication of the ground circuit's resistance.  All the 
rear end grounds are connected to one lug in the trunk.  The lug is 
connected to the body by one of the license plate mount retaining 
bolts.  It would be a good idea to clean that connection periodically.  
I do.
