I would fix the efi, the tank pump is a pusher pump, the frame pump is the high press pump. Check your fuel press, at idle and 2400rpm. Let me know what it is and by then (not at my tool box right now) I'll have the spec for you. The egr was common to plug up and this can cause pinging and some loss of power. The combination of a bad high psi pump and a clogged egr could cause that symptom.
