If the fuel pump (s) sender assembly has not been replaced BEFORE doing ANYTHING else on a low mile, long stored ZR-1, then that would be a VERY big no-no.

I will try to get pictures of the last dozen or more fuel pump assemblies that have been removed from low mile ZR-1's at our dealership.
All are nothing but rust flakes held together by the fuel tubes.
Each one we do seems worse than the one before it.
I will soon do the assembly in my car just because of the horrific messes that we have encountered in others.

Is is not specific to ZR-1's. Most all C-4's by now should have had the unit replaced. It is one of the most common repairs we make on C-4's, having done hundreds of them.

Remove the assembly.

Pump out the fuel and dispose of it properly (pricey!!!)

The ZR-1 tank has a plastic liner, so diligent wiping with many shop towels will remove enough rust to fill a coffee can or more, all from the frame of the sender / pump assembly.

Remove the fuel Filter.

Flush the tank to filter line thoroughly.

Flush the filter to fuel rail line.

Install new filter.

Install complete new sender/ pump assembly.

Now, if it just had new injectors installed; Remove them; Send them to FIC for cleaning and testing.

Put everything back together.

Fill with fresh fuel.

Good to now start.

To the OP.
A 300 mile car in the twenties, even if it needs up to $5,000.00 in maintenance or repairs is a SPECTACULAR DEAL!

The problems are simple to correct, so do not let the fear of the unknown cause you to fail to understand the true value of that car! With all of the corrective measures taken, and given it's as-new condition, that is an NCRS / Bloomington Dream Car that I would net sell for less than $37,000.00 once the work is done and that kind of buyer is found.

Our shop would easily correct it's ailments, yes, even the dreaded airbag light. It's a shame that in your case we are closer to the opposite ocean.

Someone will step up and buy that car.

Good Luck, but I suggest once again, not to waste too much time.
