return line plug
 

the smell of diesel tells me the return line plug on cyl 5 is leaking. the fuel around the injector and watching it puddle just now confirms it.

anyone know if there is a homefab that can be doe for this or do i need to order this one teeny tiny part?

Unless you just don't have the proper plug, you need to replace the line instead. Replace all of it.

A piece of 1/8 hose and a golf tee might work until you can get the proper part.

A 1/4" sheet metal screw in a spare piece of return line worked pretty well for me for a couple of weeks until I could get the proper part. Looking back if I would have wrapped some teflon tape around the screw it would have been even better.

If he had the line, he wouldn't need anything else.

And wrapping teflon tape around the screw wouldn't have helped a bit, and may have made it leak more. Teflon tape only does anything for metal-to-metal contact.

I used a form nail, (one of those nails they use for putting concrete forms together that has a double head for easier removal) clipped it to length and installed it about two years ago. Cost: about 2 cents incl. spare.

Read the original post. He's not missing the plug. It's leaking.

He does not need a plug. He needs the hose.

Thanks, You are Correct!

The only way the tiny part can "leak" is if it is missing. Fastlane, "Buy Parts" at the top, carries return line hose cheap!

I was trying to answer his question instead of looking at and solving his actual problem.

thanks everyone
 

i found an inch and a half of return line i never threw away and plugged one end with a golf tee.

matt i had replaced all the line but have never done the plugs. guess i need three.

the old one was a rubber plug one piece and the side had split open.

THis happened to my mom about 10 years ago with her 300SD. I remember I ended up going to the auto parts store and getting a vaccum line cap and squeezing it on there so we could get around the rest of the weekend and then get the proper part on Monday.

Oh, I understand. Someone used a vacuum-line cap on your last injector. Not good.

You have three plugs?
