@chris: if one of the things you didn't repair was the jet pump you should look into it: the main cause of fuel starvation if under 1/4 tank is a leak in the o-ring seal going back to the left tank from the fuel filter/FPR unit. Switching the fuel pump or the FPR may boost pressure to mask the problem but won't solve the problem that is a design flaw so every one will eventually fail. See my threads about the problem and the cost free solution.
