Fuel Return Line #23-Rubber Replacement
How do you replace the 6 inch piece of rubber return fuel line on #23? The removal isn't a big deal, but with what type of connection do you replace it with?

It's not that tough to get the rear steel section out. You can take it to a hydraulic-hose shop and have them put a new piece of rubber fuel hose there with the proper swaged fitting. The connection where the hose fits onto the steel line is a low-pressure connection, and in fact the other end of the hose is secured with a common hose clamp. I'm not in a great position to judge the reasons why the front end of the hose is a permanent connection. It might be for ease of original car assembly, or it might be because there's no way to verify that the connection doesn't leak until the tank is in place and the hose is connected again. Then you can't see if it's leaking.... So I'd look hard at duplicating the factory connection, were it mine. You might also inquire the current cost of a new piece already done up right. Sometimes we assume that it will be off the deep end, and it comes in at a much more reasonable number.

Here's my experience with that. I also had the tank out, and that short hose was a bit ratty. I gave it a tug and it slid off the pipe VERY easily, much to my surprise. Replaced with new fuel rated hose, and a jubilee clip. As for the 'not that tough to get out' remark, last time I looked the return pipe runs between the body and the rear suspension cross member. With all the bends in that pipe, and the PITA of disconnecting it from the engine bay hose and the the clips down the body, you will need to have a hoist to wangle that sucker out past the cross member. I intended to replace the whole return pipe before I saw how hard it would be to remove, so the brand new pipe still sits in the garage. The pressure pipe is much easier, as it comes from the wheel arch area back under the car, so you just have to disconnect the front end and the support clips.

a new piece of the correct Fuel injection hose and a FI screw clamp will work just fine here,
this is a return line so its not running at 55PSI,
dont remove the hard line from the car to replace the hose,
cut the swage then replace the hose .
Orient the clamp so the scew wont touch the tank when its installed
NOTE if this is an original hose replace this hose if you drop the tank..
