I glean from Phil's comments that the line pressure regulaator may be the problem, under this theory: if the regulator isn't holding pressure then the fuel pump won't work as hard thus will draw less amps. This may be the case in my case because the vacuum line from the manifold to the regulato was seriously leaky for a very ong time. The car would often quit at idle. So, maybe the lack of vacuum ruined the regulator. So I ordered one and will try it unless I discover anything else first. Thanks Phil, Steve, Dave and the other guys for the help!
