Hi all, this marks my 1st post here (been an avid reader for a while), and I'm hoping the experts can help me out. My 928 sat for 4+ years and I have recently become able to get her back up to scratch. I am not a seasoned mechanic by any means. I have basic knowledge, but the workshop manual is my bible and the experts on these forums my wisemen. I've had this car for 13 years since I was 16 years old, so getting her back to Grade A on my own is a matter of personal pride.

That being said, I've been in the process of redoing the fuel system (tank cleanout, new pump, filter, clean injectors, etc.) When I started replacing the fuel hoses, the feed line wasn't cooperating, I tried a little too hard and managed to twist up the hard line that comes from the rear passenger wheel well. Lesson learned. The line mounts under the car don't look like they come off easily, if at all, and feeding it through probably won't be an option due to all the bends and the fact that it's on jack stands, not a lift. I appreciate any advice you guys can lend.

I actually use the PET manual MORE than the maintenance for things like this. Take a look at your year model PET. The clips that hold the lines to the body have a cover that when you compress the clips will come right off and the lines are just compressed in the part that is permanently attached to the car. Might not be too bad to change out.

Thanks for the feedback. From what the clips looked like under the car at first glance, there looks like a tab is threaded through and bent to hold the clips on. I'll have to take another look at them. Hopefully you're right and it won't be as miserable to swap as I anticipated.

I have replaced my pressure line from rear wheel arch accumulator to engine (although mine is CIS, I dont think the line is much different). With the car on stands only there was no way in the world I could get that pipe fitted in one piece. Then there is the added complication of getting the hose lower end tight on the end of the steel pipe. In the end I cut the main pipe ~ 1ft back from the firewall corner, and used a compression joiner . This made it easier to get the hose connection done up properly as well. In pressure testing with pump relay bridged, I got a couple of drops out of the joint, nipped it up, dry, and no problems in 4 years+ now. The clips along the body didnt give me too much trouble IIRC.
I thought I would also replace the return line to the tank while I was at it, but that was even worse - it runs between the body and the rear suspension - so that pipe is gathering dust in a corner of the garage.

Well it's a relief that you were at least able to do it. So were you able to remove these clips, or did you just feed the line through? Do you have any pics of what you did?

Sorry, didnt take any pics. gently bend the visible tabs back to around vertical (pointing down), and wriggle the cover plate off, and the pipes will come out. A good wire brushing and maybe some lubricant will help ease things. Only disturb what you need to . Plug (or cover with small plastic bags) the pipe ends when you start lacing them into place, to minimise rubbish getting into them.
Can I ask why you are replacing the pipe? Mine was damaged badly in a ramp incident....

Thanks for the info, that makes me feel much better. While I was replacing the fuel hoses, I was under the car trying to disconnect the hose from the supply line. It's a tight spot as it is, and after multiple shots of PB blaster and knocking it a little bit to loosen things up, it would not budge. On the 3rd or 4th go, it finally popped and started to turn. Only it didn't actually pop, when I saw that it wasn't coming loose I realized the counterholding wrench had slipped and the whole line was twisting, wound up with this:



Only thing I'm worried about now is, with my luck, those tabs will just snap right off. It seems each repair spawns more repairs, so round and round we go...

Update: I finally got the line out, did it in one piece so I know how I'm going to maneuver the new one in. Had to loosen both the supply and return lines for the ATF cooler so I could get them out of the way, but those tabs bent very easily to pop the holders off, so I don't see them being a problem going back on. It was a great relief to finally get the line out.

Congrats!!

I always say it only takes three things to fix one of these cars: Interest, patience, and moneeeee!!!!

If you run out of one of these, the games over.

This is the description of my entire life of working on cars (and boats, and homeownership...)

Glad you got it figured out!

Thanks Mike, appreciate it. It's pretty satisfying when something goes right because, as I said, I am full-on amateur. I've never done this type of work on any car before let alone a 928 and there's certainly a bunch of 'you-are-way-in-over-your-head' moments (like when the fuel line twists up) that can sometimes be overwhelming.
