I've got a serious quantity of gas leaking from my '86 4Runner with a 22RE(430K miles). The gas is leaking from a line mounted to the top of the frame rail and it appears that the floorpan is resting on top of the line(which is what caused the line to break, I suspect), making it difficult to remove or even cut the line so I might be able to splice into it.

Here's the real question: Is there any disadvantage to routing a replacement line around the place where the floorpan is resting on the frame rail(I obviously cant put the new line on top of the rail again)? Do I need to take any further precautions to protect this fuel line since it isn't going in the same place the OEM put it? Has anyone seen this happen before?

Thanks for any feedback...
Y'all are the best.

The hard lines on my '85 run along the inside of the frame rail as I recall. Held in place with clamps that are screwed the frame.

Turns out that the floorpan hadn't actually crushed the fuel line... it was just really rusted. However, the floorpan was in the way of my getting to the line as the line runs in a very tight space between the frame and the floorpan. Time to clamp on the rubber hose... wish me luck!

You could always loosen/remove the 5 body mount bolts on the passenger side and jack up the body a few inches to get more room. Set a few blocks of wood between the frame and body to hold it up while you work on it.
