The only reason to install an electric pump is if you have a bad cam lobe for
the fuel pump (which is supposedly the problem this fellow has). I have a 1
1/2-2 lb pump which seems to do the job OK although I have reverted back to
the mechanical pump because I had too many problems with the fittings leaking.
I originally used the electric pump to solve my gas overflow problem.... I
have a switch under the dash (the old dashboard light switch) hooked to the
pump. To shut the car down I simply turned off the pump and waited until the
car ran out of gas!! No more overflowing gas!
Only problem was that every week or two I had to tighten the fittings on the
pump because they would start to leak. Rather then continue fighting with
that problem, I disconnected it and put the mechinal pump back in service.

Jan,
I haven't found a reason do use an electric pump and have never had a stock AC
pump fail to provide plenty of fuel, even at over 7500 rpm, autocrossing. I
have seen many cars with electric pumps that have had problems aside from
electro-mechanical failures. Craig Burlingame's Hillman Californian is a
prime example: it continually quit running, and following a hunch (because I
had seen it twice before) I determined it had 11 pounds of fuel pressure at
the carburetor needle valve, jamming it closed. There were two remedies for
this: add a pressure regulator or install a stock pump. I installed the
correct pump.
