Sounds like you have an air leak on the intake side of the pump.   We 
had a similar problem on our BN2; although the clicking was more 
erratic--sometimes normal, sometimes clicking like mad. We checked 
everything; finally my dad cut the outlet tube out of the used tank we'd 
installed and found a small hole in the pickup tube by where the tube 
was soldered to the top of the tank.  Dad deduced that the acid used in 
the flux used to solder the tube to the tank ate the hole in the tube.

Try running an inlet tube into a bucket of gas--obvious precautions 
required--if that helps you've found the culprit; if not, the leak is 
elsewhere on the intake side.

Inside the fuel pump are two one-way valves.  They are plastic discs (Moss, 
Key #6 in the diagram.  N/A).  One of them could be defective allowing 
gasoline to circulate through the inside of the pump.  I had the problem on 
a trip many years ago.  I solved it at the time by cutting a disc out of the 
plastic from a blister pack of something.  It worked and is probably still 
in my back-up pump that I carry.

The only thing I can think of is one of the reed valves is broken (there are two). How you could have two pumps doing the same thing is odd. Where did the replacement pump come from?  Was it removed for the same reason in the past?

Keith,
Check the suction line from tank to pump. The pump is probably sucking air. This is the reason for the fast clicking.

The noise means you are sucking air on the tank side of the fuel pump.
Could be due to a loose connection or possibly a blockage caused by debris
in the line. Is it an old tank? has it ever been re-lined?

Keith,

Which SU fuel pump are we taking about? The one way valve discs Len 
mentioned can be plastic or metal; depends on the model.

The pump will run faster than normal when there's a leak in the system. 
  It can be on the inlet, outlet, or internal.

As Bob said, if the pump stops clicking when sucking fuel from a bucket, 
then you can rule out the internal and outlet leaks.

You checked the carb throats - they're dry?

Cheers,

It does seem likely that you have an air leak on the inlet side (tank to
pump). 
A leak on the outlet side would be altogether wetter, messier and smellier.
You can do quite a simple test by:-
diverting the fuel from the carbs into a container
and sealing up your tank's filler pipe ie where you pump in the fuel. Use a
plastic bag and duct tape or similar effective bodge. If you manage to make
a good seal, you should hear the pump do its normal clickety click when you
switch on the ignition and then maintain its new/wrong rapid clicking. Once
it has done its best to create a vacuum in the tank, it would normally slow
down and stop. If there is an air leak, the clicking will continue and you
may be able to find it by, say, listening through a piece of garden hose run
around the pipework and connections.
Worked for me. Start at the most obvious which is the banjo connections.
They're brass and suffer from overzealous, ham fisted POs. May be just a
little loose or needing a little PTFE tape.....

Listers,

Once back home I restarted the car and same thing.  Then over several days I
attempted to fix the prob.  A different pump gave the same results.  I
replaced the filter and still same thing.  Oh BTW there was no fuel
underneath as is the case when a float needle is stuck and fuel comes out
the overflow.  No fuel shows up anywhere.

Why does the pump continue to click so fast?????  Why does it NOT slow to an
occasional click?????  What is the fix????  I am flustered.
