My 64 corvair monza is bogging down at about 45 mph. I have electronic ignition and everything from the fuel filter to pump and gas lines are new. The mechanic and I are stumped. Could the fuel pump being hooked to the starter instead of the oil pressure switch have anything to do with this?

When mine did this, it was a partially obstructed fuel line, between the tank and engine.

After I blew it out with compressed air, no more problems.

You need to give us a bit more information.

Is your '64 a 110 hp with PG, etc.?
Did you install an electric fuel pump?
If so:
a. how did you connect the electrical?
b. did you install a fuel return line to the tank?
c. do you have a fuel pressure regulator on the fuel line?
d. Where did you install the electric pump?

If you give us more info, maybe someone can help.

Yes it's a 110 hp with PG
A. To the starter it's how the one I removed was wired
B. No I cleaned lines and Just replaced fuel pump and filter that someone added before I bought below gas tank.
C. No regulator puts out same fuel psi as mechanical pump, bought from Clark's
D. Behind drivers side rear tire on wheel well.

Electric fuel pumps are good "pushers", but bad "pullers". The first thing I'd do is move the pump closer to the fuel tank and see if that solves your problem.

Joel is correct.Mount pump as close to the tank as you can.Had similar problem with my last 64 vert.PO had installed the pump at the rear and car ran fine until put under a load then starved.

I have also seen the fuel pickup screen in the tank and on the sending unit pickup... all gunked and glazed up, restricting fuel flow.
Had one rare one...
The sending unit was replaced, and it ran fine for a week or so then suddenly would quit. No fuel. Problem turned out to be a flake of solder about half the size of a dime. This was moving around in the tank and because no new sock filter was put on the new sending unit, the flake would stop up the fuel line tube on the sender. Never would have found it if that flake had not finally lodged in there. I am guessing the solder flake was from when the fuel tank was made!

I'd check the filter stones in both carbs first. If you find any junk in there, some probably got into the carbs too.

Ok bought adjustable fuel regulator today and an in line gauge put on the car before the T junction going to dual carbs. Tomorrow morning I am switching the fuel filter by the gas tank with the fuel pump by the wheel well. 2 questions
A. The fuel regulator is a mr gasket adjustable. It goes up to 5 with hash marks at the half way points in-between each number. What do I need to set it at?
B. Should I wire the fuel pump to the starter, the oil pressure switch, or directly into the fuse panel?

from running electric pumps on "other" cars I'd run a fuel filter between the tank and electric pump and mount both as close to the tank as you can I'd also wire an inertia switch into the power wire to the pump this will shut the pump down If you are involved in an accident.

Running it off the oil pressure switch is the poor man's inertia switch, and probably the best way to do it.

Here's a diagram that might help with a way to do it.
