Steel fuel lines, could these be original Options

[swl]

OK folks I've had a blonde moment here and got myself in a situation where I may have to replace the return fuel line. I've been staring at it scratching my head when I realized that the lines in the engine bay are the normal nylon but by the time we get to the front trunk they are steel. If the joint between the two of them is accessible I may be able to fix our blunder. Everything I've read and seen here says the plastic goes all the way to the front. I've had a look with an inspection mirror but can't see where the joint might be.

#1. Is this a stock config? I've owned this car since 74 and can assure you that I haven't replaced the lines. Perhap the original owner did but it seem a little far fetched to do it on a new car.

#2. If this is a familiar setup can you tell me where to look for the joint. I would suspect the firewall but don't see anything there.

#3. Just in case. The front rubber grommet - how does it come out. It looks like it wants to push out from the inside. Any hints on how to do this without buggering up the grommet.

My line was plugged with stuff over several inches.

What I did is completely remove the whole line assembly (it is impossible to remove the plastic line from the metal part without cutting, note that I didn't cut anything).

Now you have good access, I used a combination of a coat hanger and compressed air at over 100 PSI to start.

See I used a sturdy coat hanger, inserted and started twisting followed by compressed air both ways.

Eventually I managed to get some air through; at that point I used a simple flushing device to flush the whole line in both directions with thinner.

If you have time, you can try and figure out some hydraulic method of popping the obstruction out or got to a hydraulic shop that may have some solution.

And BTW I'm not a pro and never did anything like it before my project, all the skills and info are available here, you just need patience and thought. If you put your mind to it you can do it also. And the only person you can trust to do the best work IS yourself, that's why it's called labor of love.

Good luck!
