Thanks all. I'll be checking the lines at some point today. I can see the rubber line come from the top of the tank and into a fuel filter, then into some more rubber line and into an adapter that hooks up to the steel line that ultimately goes to the fuel pump. There may be an electric fuel pump somewhere in between.
I'm a bit perplexed by what I have going on at the oil filter. There is what appears to be a pressure switch (on/off) with a single blade connector on it. There is also an oil cooler adapter where there is a 3-pronged sender installed. There is a factory oil pressure gauge. I also have 2 wires hanging there that look like they'd hook up in the general area. One runs back somewhere and is clearly not factory, the other is taped up in what appears to be a factory-type harness. It doesn't seem like I have enough loose wires to mate up with all of the potential connections.
This thing was driving down the road when the engine exploded, so I'm hoping I don't have any fuel line issues. On the other hand, it sat for about 6 years after the engine failure. Age or critters could have gotten to the lines.
More detective work required. Worst case is I'll be hacking an access door into the floor of the rear bedroom....
