How to remove/install fuel hardlines without removing subframe

[need RX7]

I see no way to do this. There's no way to snake the lines through the space between the subframe and the body. Can I possibly unbolt the subframe and associated suspension pieces to drop it down a little bit without removing it completely?

Yes, you can do that.

When I made my brake lines, I had a similar issue.

When I installed the line that goes from the brake prop. valve to the rear splitter, I found it easier to sneak the rear part through the space around the differential. It took about 10 minutes to worm it through properly but I still had the subframe bolted on when I pulled it off.

Hope that helps.

Another possibility is to try Cunifer (sp?) brake lines. These are a DOT approved copper/nickle alloy line that is rather flexible to work with. With this stuff, you may be able find a way to snake them thru the tight spots. Here's a website for a shop that sells Cunifer lines, brake line hardware in general. Disclaimer that I've never used Cunifer yet or purchased from them, but the site is a pretty good reference:

PS - If you do end up using the Cunifer lines, please let us know how it went.

^ Pete, they're easier to work with than steel, SS or otherwise. I redid all my lines in Cunifer and there have been no problems so far.

I had to re-do my gas lines on the Project car,with a 25 foot roll of hardline..Alone.
What a freakin job.
But I did it..just before I sold the car!.someone else got the luxury of my Hard work!

If your replacing the lines just cut them out of there and run your new ones from the front to the back. with the alum fuel line they sell it is real malable and easy to manipulate. You just have to be very careful how many times you bend the alum line back and forth. After a couple times the alum anneals and becomes very hard and brittle.

I certainly hope you don't mean aluminum for brake lines. The fact they become brittle like that is a reason why these things aren't suitable for brakes. Plus they don't have DOT approval so I'd like to know where you can buy them?

[rxspeed7]

Never alum for fuel lines, the op was asking how to remove the fuel lines and replace them not the brakes lines.
