Get a 30 MM socket and change the delivery nozzle. It's that easy. I would get a new copper seal/washer to put on it.

Any idea where to get those parts?

Also, is there a possibility the hard delivery line could be the problem?

It appears to me that the nozzle itself is leaking. I do not see any fuel leaking at the hard line or the nut. I have a 30 mm Snap-On nozzle socket. It is special for the return line fittings. I could send you a used nozzle if you need one. Let me know.

I used a deep impact socket since I had one. Worked fine.

When it is running, it seems to be coming out around the fuel line in the center of the nut. I'll get a video soon

Then tighten the nut. 19MM flare nut wrench. But I think it is the body of the nozzle leaking or the return line cap. The nut looks dry in the pictures.

//uploads.tapatalk-cdn.com/201...dde2336d71.jpg The last picture you show the cap is missing on the return line. That will do it for sure. You need to get a set or a cap. Or make a cap. You need the PITA clamps also.

Do you have a picture of what it's supposed to look like? Thanks

Look on the other side of the engine. The rear nozzle has the one side plugged off. The picture I sent with the lines has the 2 small caps in the center bottom. That is what you are missing. Easy. Get the caps. Maybe GM dealer. Put the clamp on the cap and lube it a bit and push it on the return fitting done. Man my eyes would be burning with that fuel on the exhaust. No tools needed but maybe a needle nose pliers. Good Luck.

There is what you need. These are the rubber caps for the delivery nozzles. I hope you have the issue resolved. Good Luck.

I have looked all over and cannot find these. Can you give me a part number or a place I could find a pack like that?

Look on eBay under 6.2L diesel injectors.
There are hose kits using the high quality German made hose. Does not require the use of clamps.
Two end caps are included.

Maybe end caps available separately.

Easy find and fix

GM part # 14055301. I will check on availability, price and report back.

Rick,
We do not list anything through NAPA or even our AC DelcoSupplier

Looks like an after market item at this point. Go with Tinstar's idea. Or make some. Capping a small hose seems easy.

They will work.

Thank you. Found a ton of listings.

The German, cloth coated return lines are good. Any place that sells parts for old Mercedes will have them too. For an end cap, you can take a short section of return line and use a sheet metal screw or similar to plug the open end, maybe add some gasket goop to the thread.

Got it running again leak free. Headed home and started to lose throttle response. Put more fuel in it and still no crank. With the 6.2, is there a manual way to prime the fuel system?
