Question Fuel lines repair or assemble

Hello fellows, the question for today is on the 924 fuel lines (all) how do you make new ones. Do you use your old connections? If not where can you find new ones? And, how do you go about attaching the ends to the line? Thanks (have bought new injector lines) want to replace all others.

post your car in your signature. I'm going to assume that you are talking about an NA 2.0L 924. I haven't seen any replacement lines out there so you would need to find your own hose and reuse the fittings. To do this you'll need high pressure line that can handle 100+ lbs of pressure. cut the sleeve off up be the top and then take the barbed ends off and put them on to the new lines and recrimp new sleeves.

Honestly I have no idea. You could probably just get away with using a piece of tubing and crimping it on there nice and tight. Just cut a piece a 1/4" long so it looks like a ring and cimp it. Are the lines leaking? If they aren't leaking I wouldn't bother trying to take them apart and rebuild them. Also if you are interested I will have a full set of non leaking lines from a '79 along with fairly new injectors in about a week or two.

We have 4 new fuel lines to the injectors and injectors ordered, but all the other lines are old and brittle, and want to replace all so we can eliminate a multitude of problems later. If you have other fuel lines or if we can use what you have else where on my son's car. (I don't know and hope you know if we can use them elsewhere) Please let me know. 1978 Porsche 924 Thanks for your replies

The flexible hose lines have to be assembled from the existing fittings. "Sleeves" are what fit over the end of the hose and are crimped to hold the hose on the existing ends. This is necessary for the high pressure side of the fuel delivery system.

You may be able to take your flexible fuel lines to a good part store or they my be able to tell you where you can have the hose part replaced. Crimping the sleeves is done with a special tool. Not something that is done with a pair of pliers.

One of the places to look is where farm tractors are repaired. These use hydraulics to actuate their implements (plows and such). They rebuild hoses all the time. If you are asking about the steel lines that run under the car then these can also be remade at a good truck or tractor repair shop.

Have you checked out www.924.org's discussion board? They should also have a list of resources.

Hello, We finally figured out Hydraulic Fittings would work. Would good stainless steel clamps work or is that a completely stupid idea? I know I can find a farm equipment place around.

You have to keep the metric ends to your lines unless you change everything over to inches (not advised). For some fuel lines you can use wide band worm screw clamps of the correct diameter range. I would still have the lines remade at a good shop where they pressure test them before giving them back. It's worth the peace of mind.

Some of the fittings on the injection have to remain metric.

Tractor or heavy truck repair shops. Or a good speed racing shop where they race sports cars. Start calling around.

You could probably find all good, used, later type all steel injection lines (early ones are braided) that go from the metering unit to the injectors from a Porsche salvage yard. You might also look at any Golf or Audi with CIS and see if the lines will work. Otherwise, the cost and time in doing the lines will be more than the car is worth.

Does this 924 acually run?

Actually, we was told it did, but needed injection work..But, even I can look at it and tell it need more than injection work. I think they took a little problem and turned it into a huge problem.

If it didn't run and doesn't now it's basically a parts car.
Yes, you can fix it, but unless you have time, tools, parts and ability to find them at good prices, knowledge and will, it's a garden ornament.
Don't like to be brutal, but having been in the automotive repair business for longer than I want to remember I've been all through this before with people. At the end of the day it's always cheaper to buy a car that is running and driven right now. Might still need work but you can drive it around while it's being cleaned up. 924 prices aren't going up.

Boy, that made me feel better. (Just kidding) The history of the car is my husband traded for it back in 1996. Put it behind the shed where it had stayed. My son which has just turned 14 wants to take auto mechanic's in school when he can. I also told him what you said that we could buy a good car instead of dumping the money in this one. So, I told him this will be his car and we will help him with it, but he has to stick with it.
I have shopped around on the internet and ebay and have found prices 1/2 or even less than some other places. We have worked on several automobiles, but nothing imported.
I really think we can get the baby off the operating table and walking again. (Man, I hope so) Thank all of you for your replies. It is really helpful.

I hope he sticks with it. Make sure you ALL look at this car very carefully and find out exactly what repairs are needed. If your son wants to take an auto-machanics course, this car could be a a good project..as long as it can be fixed and repairs aren't unrealsitic.
I would go about and find a parts car (try Craigslist.com). If your son has the skill and mechanical aptitude, there is a shortage of people in the auto repair industry.
Good luck too!!
