I'm certain you already know this, but mechanical and electric pumps are different. Mechanical pumps are designed to suck gas to the engine and can be mounted right up front. Electric pumps are designed (all of them) to push fuel and therefore work best when they're as close to the gas tank as possible. Please tell us where your electric pump is...or please answer this: is your electric pump for some reason between the mechanical pump and the carburetor?
