| Remember that how much fuel the carbs consume is relative to how much power 
the engine can make.  So, a modified engine with twin HS4s will pretty much 
consume the same amount of fuel at WOT as a modified engine with twin 40DCOEs 
assuming both modified engines make say 100bhp.  The only exception being when 
you floor the throttle at which point momentarily the DCOEs will use a bit more 
fuel.  
The other issue will be what mixture strength the engine is set to run at - a 
full race mixture - say 11:1 even on a road car will always ensure the engine 
consumes more fuel than say a more highly modified engine with mixture at say 
13:1.
I'd guess that if you have a  fuel regulator it provides an extra measure of 
fuel reserve compared to not having one.
How long will the engine run at WOT - 5 minutes or half an hour?
Probably twin 40DCOEs are too much for a modified 1500 Spridget but try and 
find a pair of 38 DCOEs and you might be looking for a long time.
I'd expect quarter inch line would be OK, without checking I think I run all 
5/16 on my car and use a non standard fitting at the tank end.
