Slant 6 Turbo 68Dart Project
im gonna say no to the pickup and no on the timing. you are getting a lean condition. the timing isnt going to affect that that much and i have the stock pickup in my tank and i am pulling a lot of fuel through it with no problems what so ever.
something is causing your fuel to stop. either your bowls are draining and you are just running out of available fuel (pump isnt keeping up for some reason) or the boost is pushing the fuel back out of the line. do you have any filters in line? before or after the pump?
