seeking advice
Yeah, I know "not another glow plug thread" I've searched and searched, and will keep searching as my post waits your message, for the answer to my problem.
So I installed new hook type (not pencil) Glow plugs in a 1978 300D becuase my strip fuse melted and didn't have a meter to test each GP. The engine started after installation, but this morning the strip fuse melted again at startup. I noticed a little amount of smoke coming from a wire or glow plug and I noticed 2 cracks in the fifth glow plug insulator, though don't think either suggest the problem. I heard somewhere that a fuel leak from an injector hose could cause Glow plug failure, if that is the case then my last glow plug might be affected from a injector return leak, but would that cause the fuse to melt? Here are some photos. You can see the leak from the hose by the injector and another with first glow plug and its attachments. Thanks for the help.

The old loop-style plugs are not as efficient as the pencil style, so when they start heatiing up to max temp they'll smoke a little - lost heat. It sounds like a short is blowing the fuse, but then again those strip fuses aren't the most reliable. Put another one in and see what happens.

are you sure
you got the wires on correctly for the glow plugs? they are a little tricky if you arent familiar. and i think if any are loose or not making a good connection you will get wierd things happening.
