I think the leaks are fixed now. One of the main coolant hoses from the engine to the radiators had a hole that leaked under pressure. The fuel filter is tucked in where the coolant hoses go forward, so it was easy to replace while I was there. I drained some fuel into a jar to see how dirty it was. Glad I replaced it.
I drove it around town and took it to work tonight. No sign of leaks; oil or coolant. Looking down from my office... That's a lot of red.
There's plenty of things to take care of next. Too much to list to make the car 'right', but for now the only thing I feel urgency about is replacing the rear tires. I kind of like the 16" wheels on it and will probably keep them. Most likely I'll find some inexpensive daily-driver tires to make it safe and swap a set of 17s on if I ever feel the need to 'drive beyond' the cheap 16s.
