16-Jun-2025 : new fuel pump. The old one was leaking. I purchased the one with the glass (I grew up with these and I like to see the gas - easy to check if you have fuel). It was $20 more than without the glass - money well spent. The rebuild kit for the fuel pump was almost as much as the fuel pump itself.
Next on my list: replace the fuel sensor.
It may be that I have the wires reversed on the instrument panel (since the wiring and instrument panel are upgraded). But I figure a new sending unit ($21) can't hurt. My first step in diagnosing would have been to connect a DMM across the old sending unit - but to properly measure I'd have to remove it anyway. Given how the gaskets on this old girl are... crispy... it seemed wise just to get a new unit.
Oh, it also could be that I don't have enough fuel to register. I've hesitated to fill her up - I'm still chasing leaks and such. I guess at this point I could do that.
