To start off, this is not a Ford and I apologize.I recently bought a 1986 Pontiac Trans Am to use as a daily driver, it came from the factory with a T.P.I. 305 and a 700R4.

The car sat in a barn for 8 years and then the guy pulled the T.P.I. stuff off and put on some carb stuff. I then bought it.

When I bought it, the car still had the T.P.I. wiring, computer and the in-tank pump. All he did fuel wise was throw on a Holley regulator.

I removed both the wiring & computer and now the in-tank pump no longer works. Now I have 3 options:
1)I can run some wires to have the pump come on when the ignition is on and run a return style regulator(Mallory #4309) and call it a day.
2)I can drop the tank, pull the sending unit. Replace the pump with a tube then run an in-line pump of some sort.
3)My actual question, I can just put a mechanical pump on the side of the block. The problem with that is, Can I pull fuel through the existing in-tank pump with it not on/working?

Any thoughts, opinions, help is appreciated. Thank you!

No you can not pull through the pump with it not on. Why don't you just pull the tank and put a fuel cell in and run a pump of the block?

The exhaust clamps/exhaust is rusted together and I'd need to cut it off. Just didn't want to have to replace the exhaust system to pull the pump.

If the in-tank pump is still good, I'd wire it through a separate switch .

I like having a hidden switch anyway.

I'd also wire in a ford inertia switch for safety .

Ya switches are cool and safe for the owner too.
