I have seen perennial probllems with the floats in the carbs leaking.  When
this happens they fill with petrol and sink causing the phenomenon described
here with petroll pouing onto the floor and the fuel pump ticking furiously. 
The solution is to replace the float, but beware I have had one of the new
ones suffer the same problem.  I had the same problem with the fuel sender on
an old F350 truck.  In that case we were able to find the leak and drill the
hole out so we could re-solder it.  

One of the carb floats is sitting on a
shelf in my garage and after 2 years is still full of petrol so these pinholes
are very small and the problem can take years to occur.
I hope this helps.
Jeff

Assuming things
were running well before and the aftermarket pump isn't 
pushing too much
pressure?
Most likely caise is crap under a float needle keeping the fuel
flowing and 
overflowing the rear carb. May be lucky by simply tapping the
rear float lid 
to dislodge the dirt and allow the needle to seat fully and
shut off the 
fuel flow as intended. If that doesn't do the trick, unscrew
float lid and 
clean the needle and seat area. Check float level adjustment
while there and 
make sure the brass seat is screwed down tight.
Might need to
consider cleaning the fuel lines and installing an inline fuel 
filter before
the carbs.
