Walter, Fuel pump noise issues are hard to solve. And Alfa's sold in North America in the 70's present an even bigger challenge.
But since you have stated that you have a "1974 GTV 2000 fitted with Webers", I will assume that you have some sort of low-pressure electric fuel pump. (Some earlier Alfa's had mechanical pumps fitted to the engine, but I doubt you have one of those.) My understanding is that no '74 2.0L models came to North America with carburetors, so your car is either from somewhere other than Canada/USA or it has been modified since it has arrived. I have little knowledge regarding European (Weber) models from 1974 with regard to fuel supply pumps. But I do know a thing or two about cars converted from the Spica fuel injection system to Weber carburetors. The most reliable type of supply pump is the noisy, solid-state type of pump. These are widely available and virtually identical. While very reliable, they can be noisy making a ticking type of sound. Mounting location and method can greatly affect how loud the pump seems. Its a good idea to use longer screws and place rubber grommets between the pump and the mounting surface. Even better is to mount the pump to a piece of plastic or wood and then mount the assembly using grommets. - Eric H., Marietta, GA 1976 Spider - 1991 164b - 2009 Mini Cooper S - 1984 Cadillac Coupe DeVille -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
