BHP and fuel pumps
I've got a 1991 1600cc CVH with a carburettor and as far as I know the fuel pump is mechanical. I've heard that by using an electronic
pump instead of it's mechanical counterpart, you decrease the strain on the engine and increase BHP. I don't know how true this is, and I
would imagine that any gains would be nominal, but can you use electronic pumps on engines with carbs?
Any comments welcome.
Cheers,
Chris.

Using an electric pump over a mechanical pump isnt really gonna get you any higher up the bhp stakes, it is minimal if anything at all!
However, if choosing an electric pump, dont be tempted to buy a pump designed for fuel injection as these run a much higher pressure than your carbs
are designed for and will lead to over filling by a considerable amount 
Pacet have a large range of pumps and a simple solenoid pump should do you for the power you are likely to get

Loads of cars fitted with carbs and eletric pumps. The Mini had one and you new when you was out of petrol as you could hear the pump beating like
made as you rolled to a stop.
Can't imagine the power saving would be worth the time and effort of the change unless it was because the standard pump needed changing or not
up to the job due to tuning.

Dont need a lot, around 2-4psi should suffice depending if your going to do any future mods that require more fuel
In comparison Injection pumps run at around 40-60psi
