Use a water level to determine elevation of tank outlet

- I can test the line to see if it leaks. The line looks like crap, and it's really a bad idea to leave it in there. But the thought did cross my mind for a brief moment. I thought that maybe this fuel hose was some metal hose that was just rubber coated, but it's not. This is a bad idea.

- I thought about some how running a new line from somewhere more accessible, but then I would have to plug the old line (which is old and seems damaged), so that defeats the whole purpose too.

- I could simply not use one tank if one line is leaking and the other is fine. That is also a poor plan.


These ideas are better:

- Cut / disconnect the fuel hose on each side and then thread some pipe cleaner in there to see if I can feel where the line goes. Perhaps I can make it stick out into the tank so that i can confirm the location of the outlet hole. This would be done prior to poking any holes in the chassis.

- I can poke an exploratory hole in the fender well. Somewhere in this area:




I think that this is going to have to be the best option, and I will have to make a *ton* of measurements (like a surveyor) in order to figure out exactly where my hole should be drilled. It's too bad I don't have an ultrasound machine or some type of x-ray machine that could see through wood. I do have a "stud finder" for walls, but I don't see how that could possible be useful. I also have a stud finder magnet that is ultra powerful and can find metal through walls - maybe I will grab that from work and try that out - there might be a hose clamp that is right on the other side of the wood that the magnet will hang on to.

I suppose that if I make an "access panel" to get to the bottom of the tank, I can then reinforce it with steel. My big concern is cutting a hole in the wood chassis and weakening it a bit.

- I can try to cut the fuel line very close to where it enters the "bulkhead", then shove it in there and then stick my camera in there to see if I can see anything. This would screw me in case I needed to somehow thread that line back again, but I don't really see that happening.

I'm so glad that the tanks have already been replaced. At least we don't have to cut the entire car apart. I will send this post to the son of the guy who replaced these tanks - he's like 87 or so years old now, and may or may not remember this from 40 years ago. That's like me remembering what I got for Christmas when I was 8 - probably not going to happen. I'll also send this to the guys in the UK for advice.

Okay, I'm ready for some help and advice on this - I'm stuck. Thanks in advance!!!

Wayne,
Since the outlet of the tank shown in the video is on the vertical wall of the tank, use a water level to determine the exact elevation of the tank outlet at the area you circled in red on your photo. The one tank shown in the video shows that the line from the tank to the pump comes from below the tank. One of your photos appears to show the other tank feed comes to a pump in the engine bay. Is that correct? If so this would not work on that tank. Either way consider using a water level. Very simple but is accurate and handy. To get the centerline elevation of the tank, fill the tank to the center line of the tank outlet.
