Today I waa changing glow plugs on my 300D and I accidentally knocked out the diesel end plug the braided fuel line. Its squirts and foams fluid when I start up the car. I just orderd a replacement parts, but does anyone know a temporary solution to block fuel from coming out of the line until my part comes in

Literally anything that fits snugly? Off the top of my head: a pop rivet, a golf tee, an action figure lightsaber, a piece of sprue from a plastic model kit... Doesn't have to be fancy and there isn't a ton of pressure there.

agreed that any short piece of fuel line plugged up works.
I used to purchase official plugs then realized even a vacuum plug from local
auto parts store, or a piece of that injector line plugged up works.
If you do not have some extra fuel line around, you will eventually when you
go to replace the lines.

They typical vacuum line type plug you could get at an auto parts store won't last long as the Diesel Fuel will get to it.

A lot of people cut of about a 1 inch section of the braided return line and screw in a fine threaded screw into one of the ends. In my case I filled the threads of the screw with silicon sealant.

NAPA carries the braided fuel return line and as mentioned the VW Dealer (1980's VW Rabbit Diesels) used to carry it New VW volkswage return line part number New Part #- N-020-353-27
Since the price of fuel is high it is a good idea to carry a meter of the braided fuel return line in the trunk so you can change it on the road if you have to. Typical vacuum hose that fits does not last long. I have used Silicon Vacuum Hose for the return lines and it worked fine but got hard as rock after a 2 years of use.One of the stock parts for the end plug consisted of a metal plug that is cylindrical on one end with a ball on one end inserted into a short piece of the regular fuel return line or a formed rubber cap. Of the 2 the metal plug in the regular fuel return line lasts longer.

NAPA sells 1/8" fuel line that is diesel rated and seems to hold up better than the braided line I've bought from this site and elsewhere. I try to keep some in both of the SDs. A small, inexpensive plastic fishing tackle box holds fuel filters, line, wire cutters, pliers, shop rag and crescent wrenches.

I'm constantly amazed by the extreme over thinking that happens on this forum.
I've been using odd nails for years. Never had an issue. Current car has a machine screw (no silicon to fill threads either).

I have a few hundred 303 stainless steel plugs on hand in my shop that I had machined to accompany the green nylon braided viton line I had manufactured.

Let me know if anyone needs one.

Best. Answer. Ever.

For the entire time I owned my '84 300D it had a stainless steel bolt in the end line. Never got around to changing it, mainly because it never leaked.

In my case I always have a few tubes of silicon I keep in the frige so why not use it before it drys up.
