I need to change my fuel lines...
how thick are they?

will it be better aluminum, rubber or stainless?

Thanks

 

.. anybody?...

 

What lines are we talking about here, the flexibles connecting fuel rail to injectors, or others as well ?

 

I'm in the middle of changing my fuel lines as well. I went to change the fuel filter and the lines are so rusted that the nut to the filter will not even turn without rust breaking off. I believe the feed line that runs from the filter is around 1/2 in. and the return line appears to be around 3/8 in., my sizes might be off, but close, I ended up buying a 25' roll of aluminum fuel line from the local auto parts store, with compression fittings and plan on installing my own line. I was told that the standard fuel injection rubber hose might not be strong enough over the long run, so I was advised to use metal or jaguar factory made rubber/plastic lines. Also, I would feel that stainless would be a very good chose, but expensive. If you go to a speed shop, I believe they have coated fuel line that will also not rust, but I don't know the price. I hope this helped.

 

oh... I'm sorry, forgot about that... right now I'm working from the tank to the fuel filter (inside the drivers side front wheel well).

the lines that come from the tank are steel breaded they had some rust, but I was able to wire-brush and prime... plus they looked expensive to replace.

 

I was thinking the same... yesterday I went to the local parts store and they had the 25' roll of coated steel... I would have bought that except that I read somewhere that they are a pain to bend; you have to have special tools so that they won't kink.

Also, I was concerned about the diameter... you definitely don't want them too skinny because you won't get good supply... but I'm not sure what will happen if you get them too "fat"... maybe your pump work work correctly?

 

The sucess of DIY pipe replacment depnds on skill, tools, patience, and the complexity of the pipes in question.....and how fussy you are about the appearance of the end result :-)

I've never been very good at it so I take pipes to a place like this.....

....and have them duplicated.

Most decent sized towns will have a similar vendor, usually over on the industrial side of the tracks, so to speak. They often cater to truckers, farmers, manufacturing plants, etc. but they should have no problem at all with an ordinary fuel pipe.

The outfit above will duplicate a pipe/hose/whatever if you send it to them...providing the size makes it practical for shippping, of course.

Cupronickel pipe is best; easy to bend, although neater if you use a proper pipe bender, and no corrosion.

 

If you really want pre-bent lines, I believe you can get them from Conventry west, at about $75 dollars each plus costly shipping charges, cause they are large. As I mentioned before, from the back to the front of the car the fuel line is mostly a straight line on my 93 ragtop, so I'm going to try it myself. I my end up buying the pre-bent if it doesn't work out, so Wish me luck!
