Do yourself a favor and get a flare nut wrench. It will keep you from rounding the nut when tightening it.

Greetings,
Ms. D. Mr. fo makes a VERY good point. There are 2 Harbor Freights within 30 miles of Palm Coast.
Search results for: 'flare nut wrench'
IF you've got a Mercedes they might be metric. Check first.

How about a proper metric wrench?

Greetings,
Mr. BB. Well, one should always attempt to use a wrench that fits but for pipe and fitting work, as Mr. fo so correctly states, use of a flare nut wrench greatly minimizes the possibility of rounding over a nut. Rounded corners are not a big deal if you can simply throw on another nut but those babies are captive and require a flaring tool to replace.

I was simply trying to point out that she had used a 3/4" SAE wrench to remove a Mercedes (very, very, metric spec engine) part.
I am aware that 3/4" is almost interchangeable with 19mm but...
By the way, many of the Mercedes engines I have removed injection lines on did not have the room for even a very expensive, thin wall flare wrench. Then you were forced to use a proper metric open end wrench. Thankfully, the injection lines were not typically torqued beyond the ability of a good open end wrench to remove easily...

I will do all these suggestions. I did not know the washers may not reseal. I think I have a flare nut wrench. This was an estate sale and ALL TOOLS, and additional parts came with the boat. I even have additional original hardware.
Thank you all! You make my life a bit easier, even though I was hesitant to even try this job. Phew!

Greetings,
Mr. BB. Oh. Gotcha. Sorry for the misunderstanding on my part. Ms. D. Take careful note of Mr. BB's comment regarding proper application of Metric and SAE tools. Does the wrench/socket REALLY fit or does it just sorta fit?

If no one is going ask... I will. Why is there a line *under* the injector?

A return line? And if it is there shouldn't be to much pressure

It needed a weld and yes there is a return line. I have a friend that welds and lucky for me an engine guy who was able to re-install it before the boat parade.
I was just too busy with work and the Christmas season to fix it myself. Some things I would rather just pay for. Thank goodness for friends!

In general, if the copper seals they must always be replaced, or heated to a red-hot because as they get harder and tightening the connection is leaking.
