What is the purpose of the cloth?

I believe it is to protect the rubber. Plain rubber hose may not last as long as cloth covered hose.

Usually a cloth or weave layer is to strengthen the hose, not really protect it. Look at cross sections of a variety of hoses. Note that plain old hose has no thread. As hose is rated for more pressure, there is also more thread. Older hoses had weave on outside, modern hose has less thead, but it is integrated into the carcass.
Some what addressed in previous posts, but clearly the best answer is always, "Identify where the leak is coming from". I say this only to address the same issue in any other system on the vehicle. The process is the same although the solutions may be different. This usually starts with cleaning the area and observing for leaks. No one seemed to mention that you could also have a valve cover leak if it is oil that is pooled and not fuel. Injectors rarely ever leak, if so it could be the hard line connection to the top of the injector. 99% of the time it is the bypass hoses that are in failure. If you are planning to use biodiesel in in the future, consider buying 1/8" viton hose. It will hold up better than the stock hose.

I had this same problem, on cylinders 4 and 5. I had recently replaced the injectors (torqued them myself) and soft return lines I didnt think that was the issue. Went thru two sets of soft lines cutting new jumpers and spraying everything down with brake cleaner, trying to find the leak. Asked the company that rebuilt the injectors they said that I could seal it with loctite or take it apart and lapp it, even showed me their lapping kit...
In the end, I cranked down the hard line where it attaches to the injector and on both cylinders that solved the problem.

Sleepstar said "well, i did that, but i dont need 5 meters of hose, and i;m not sure if the other hose is for the return lines.. sorry anyway"
I for one am waiting for an answer I need to replace those hoses too but different widths lengths is confusing. Please be specific IE.. you need 3 ft of 5/8" (diameter) hose listed on this site at the following link (at this point you copy and paste the location. |

For just return lines you need about a meter of 3.2 mm hose. Viton is best but just about anything will work for a while.
