Cycle the tank pump? Like 40 times with a vacuum on the exit? Crank, crank, crank.

Did the tandem pump fail because the lift pump failed? The tandem pump is not particularly good at lifting fuel from the tank through the filter. It's designed to provide pressure, not suction.

Thanks everyone for the replies. I got it primed and running. It had been leaking for awhile at the gasket. I changed it because I was starting to get diesel in the fuel and since it was leaking quite badly on the external side, I thought it may be the cause of my diesel in fuel.
After checking the oil level today, I think I am still getting diesel in the oil
the only thing I can think of is injectors are leaking into the crankcase past the o-rings. Mileage went from 38-39 to 32-31 mpg.
Any thoughts of something I may be overlooking? This may be the final blow that gets the car parked for good. I cannot afford injectors or the labor required to replace them ATM.
186k miles and as far as I know it has the same injectors installed that it rolled out of the factory with.
