Yeah...thats a good idea. I have run into that before ,but mainly on high pressure fuel injection systems and especially with diesels. What I'd do is remove the line after the pump and attach a length of fuel line to run to a bucket or gas can...that way if the pump starts doing its pump thing it doesn't soak the engine bay in fuel...also if it seems to be pumping plenty of fuel...you might check the float levels in the carbs...if they are set too low not enough fuel will enter the bowl to keep the engine running.
Wish I could help with the wiring diagram...mines B&W also...makes it interesting tracing electrical gremlins.
