Hi everyone
My 79 280 se has a new pump, filter, accumulator etc and when I put it back in I noticed a leak :)
The leak is from the connection between item 27 and the pressure line in photo attached.
I have tightened the connection as much as I can, but no joy!
What is the best solution? What is this pressure valve (27) as I do not seem to able to order replacement as I think it's jammed solid.
Any suggestions appreciated.
Thanks
I am guessing you are using new crush washers? I have found that sometimes using aluminium vs copper or vise versa does the trick, but regardless you have to use new ones on both sides of the banjo fittings.
I cannot help on valve "27" have not seen this before.

I did and no joy! I fear I will have to get a new set of metal pipe lines.
What is worse, while tightening 27 (whatever it is) it crumbled :( Now I need to find a solution to that too.
The compression hardens copper washers. However, they can be reused IF you anneal them. Hang it on a thin wire and heat it till cherry-red using a propane torch, gas stove burner, etc. Then plunge into a bowl of water. Good to go! This is pointless, of course, if the washer isn't in pretty good shape to begin with. Running it over a flat file before heating can help recondition.
That regulator gizmo is not depicted in any w/shop diagram I have or seen. I have examined early 6.9..late 450....set up. I have recently worked on a KE. not there either!?
If it's now fallen to bits you might as well by pass it.
