    Does anyone have a suggestion on how to replace the fuel vent lines that are located behind the heat shield? It doesn't look to me as if the shield can come out with the engine in place, and I don't see a way to reach in there from the top to disconnect the hoses. Any sage advice?

    Can you be a little more specific b/c I replaced mine, but I can't figure out what fuel lines you're refering too?

    Thanks, I'll try:

    The lines that run the width of the car between the fuel tanks and the heat shield facing the engine. I believe they are all evaporative or vapor lines. I'll attach two images from Ricambi--on the first it is line #2, on the second it is line numbers 19 and 20. It seems that there is a second line running parallel to #2 that goes to the nipple on the upper left side of the drivers side fuel tank visible just above the filler neck, but I don't see it on the tables.

    I'm really wondering if there is some easy way to move the heat shield out a little bit that I can't find. Since line #2 is underneath lines 19 and 20, I don't know that I can pull it through without removing them. Also, I just can't get my hand into the slot that access the nipple next to the filler neck.

    I hate to just skip it, but I'm wondering if the engine has to be out to do these ones.

    Thanks,

    Peter

    I ran into the same problem on my 87 Mondi. Those lines are still coiled up and in a bag. They will come out when I pull the engine in 5 years or 30K miles. They are evap so I'm not worried about them rupturing and creating problems. The evap may never be an issue except for a vaccuum leak maybe?

    I looked and looked for a long time. At least one of the lines I couldn't follow to it's end, it just disappeared into the heat shield like you said. After too much time looking and thinking, that is when I coiled them up and put them away. I checked the ones I did off my list so I'll know when the time comes.

    Being that they would only see fuel vapor, they would theoretically last a little longer than supply lines. However, the stuff in liquid fuel that eats the rubber exists in fuel vapor as well. Still, having a failure in an evap line will most likely not result in a catastrophic event like a supply line failure.

    Guys,

    I don't have a Mondi so take what I say with a grain of 308 ......

    1) Disconnect one end of the old hose, attach the new hose to that old hose via a hole in each and a zip tie and just pull & push C A R E F U L L Y. This has worked for every piece of equipment I have ever used it on.

    2) PM DaveHelms. http://www.scuderiarampanteinnovations.com/solutions.htm

    If you did not get your hoses from him JUST STOP WASTING YOUR TIME RIGHT NOW. Do it RIGHT the first time or JUST DON'T DO IT.

    Remove the rear deck. Borrow 2 stages of scaffolding and an expandable painters plank. Set the scaffold stages on each side of the car and span them with the painters plank. You will have complete and easy access to everything behind the plenem.

    I have replaced all the lines in 2 cars, but in both cases, I first pulled the engine. This may seem a bit extreme, but if you're intent is to someday do a complete engine / engine compartment service, in the long run, this is the easiest (and least bloodiest) way. At the same time you can easily replace all fuel and water lines, do a major (and complete) service on the engine, repack the CV joints, and detail the engine compartment. And I will bet you will discover other issues that will need addressing. When finished, you're good to go with a safe, dependable car. Think about it.
