I have noticed slight fuel leaks around some of my injectors recently. Do these leaks usually come from the braided fuel hose on the leak-off connections or from the injectors themselves needing tightened up. If so do they need to be torqued?

Or is there something else around that general area that needs attention???

Is the braided fuel line common at auto parts stores or should I order it from fastlane and wait.

Thanks from a humble neophyte!

So far the leaks in that area on my 300D have been from the braided hose, particularly the end one with a plug or ball bearing inserted to seal it off. The braided hose is pretty inexpensive from most of the MB sources. I would order and wait if you can.

Yes, you've been introduced to the ole braided hose trick. Get 'em from Benz.

If the leaks are slight, wait for the parts. If worse, and you need the car, I have done a fix by cutting last inch off and reattaching the hose..

There are two common leaks from injectors, three if you don't tighten the steel lines properly.

The braided lines last a few years, and when one starts leaking, just replace them all along with the end plug.

Also there will occasionally be leaking oozing up from underneath the base of the injectors. If you see this, the injectors may have been put in place without the seals underneath. What happens is that they stick to the bottom of the injectors, when removed, just enough that they come out of the bore then fall off. The engine will run if put back in without them, but fuel will seep and I have to believe that there is a small pressure loss as a result. They are cheap and easy to replace so keep them in place.

Good luck,
