I'd not stop there.
The hoses over the rear axle, and at the engine.
The hard lines need to be looked at for rust.
The rails need a look for rust.
The injectors need to be cleaned.
Ok, thanks Chuck. The injectors are out and I have new lines going to the fuel rail. The fuel rail is okay but I do need to look at the lines under the car. I plan to get 42.5# ers and fire it up after I fix a couple wiring problems and get the new tank in.
