Looking at a manual I found online it says about using a slide hammer to remove the injector, is that ever right?
If so where do you get the correct fitting for the slide hammer.

Just ordered a new one from a company that supply lister parts, hopefully that’s this problem sorted.

Not gone any further yet, trying to work out if I have to remove the complete head or not to get to it.

The pipe comes up from the sump and feeds the top of the engine via 3 banjo connections.
The one I have is leaking and has been repaired very badly

I’m after the oil feed pipe for a 3cyl lister petter engine, part no 203-31671.
I’ve seen one on eBay but it doesn’t look new to me

I’ve got 2 injector pipe leaks, it appears to be coming from above the top but, ( lister petter 3 cyl engine ).
I’ve taken the top cover off and this is what you can see, ( hopefully in pic ).
How do I remove what’s here to get to where the pipe joins on.
If no pic appears please click on link above

I’ve tried Imgur and the link below but I still get them to upload in my threads.
I’ve got them into the gallery but that’s about it.
Explain to me in simple terms please

On closer inspection it appears the leak is running down the outside of the long connecting nut at the top, so I would say whatever it screws into is the culprit.
How much has to be removed before I can get to the connection

Well, the steering valve seems ok with no leaks, unfortunately the oil feed pipe repair was unsuccessful, so a new one will be ordered. Another little leak seems to have appeared, 2 of the 3 injector pipes are leaking from the top connection, I removed and cleaned them and they’re still leaking. Any...
