As I mentioned in another thread, the PPI on my car revealed that my fuel lines are quite loose at their connectors, so I'll have to replace or rebuild them. Are there any special precautions I need to take when I remove them, other to remember to not have any open flames nearby <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" /> ? I know the system is pressurized; do I have to do anything to "de-pressurize" it, or do I just unfasten the lines, and let the gas pour into a bucket? Does it matter which one I remove first? As long as the pump isn't running, I can't see why a whole lot of gas would pour out, right? Thanks.

are you sure the lines need replacing? that is pretty rare to have them be loose and not leak - have you tried tightening them up?



make sure you use 2 wrenches on any fuel line, and twist only on the thing you want to twist - failure to do so results in breaking things you don't want to break





let the car sit for about an hour before cracking the lines loose - it should lose all pressure in that time - have a rag under the fittings you crack loose to capture any fuel - dispose of rag safely

The guy who did the inspection was adamant that they lines are loose, enough so that they will soon leak and become a fire hazard. This shop works on nothing but Porsches, and his knowledge of the car, from my discussion with him, seemed to almost rival Pete's. So I have no reason to doubt him. My problem is, without getting the hose off, I can't really tell where he says it's loose. He says the rubber hose is loose on the fitting, and since it's a crimp type fitting, there's no way to tighten it. So he's not talking about the connectors to the metal lines that are screwed on. Does that make sense?



In any event, you've answered my question about how to remove the hoses. Thanks.

Sounds like a very unusual failure mode. However, if some ham handed mechanic in the past took them off without backing up the non-turning connector that could happen. I tell you one reason some loosen them without proper backup...It takes an 18mm open end wrench!!! Who the heck has an 18 mm wrench??????????????

To be honest, I'm not completely clear on what the failure mode is. That's why I want to take one off and take a close look at it, and I'll post some pictures in hopes that it may help somebody else.
