Car has been sitting for 10 years

I work at a garage part time with about 40+ B bodies that we’re slowly making drivers again. So far we’re almost at 100 percentage for Mopars needing a new Carter mechanical fuel pump. The fuel pumps just crap up and stop working. Next we replace all of the rubber fuel lines (the ones near the fuel pump, carb inlets, and on the back end near the sending unit). Next we replace spark plugs (spray some marvel mystery oil in there while you’re at it). Oil change and then we will prime the motor and see if we can get it to start. You would be amazed at how many of these Mopars will fire right up; after sitting for XX years.

Edit: We bottle feed when trying to first start the car and gradually will try to pull from the fuel tank (after we’ve ascertained that the fuel pump can pull fuel). We have run into several tanks filled with varnish (Red wine colored liquid that used to be gas). In the extreme cases... the tank gets replaced along with the sending unit).
