Gq td42 injector pump leak

[Deano2506]

G'day all.
My pumps developed a leak at the back
It's either the delivery valves or the big round bit in the middle of them.
My question is does the pump need to come out to fix this? or is it something i can do with the pump still in place?
Cheers!

Sure it's the back and not the top ? Best way to know for sure is start it up and get an air duster hose onto it , mine was leaking from the big o ring under the top plate .
From memory there are only three o rings in the thing that are upper and can be replaced without removing the pump just depends on how (in my case stupid) brave you are .
There's a thread on here somewhere where I took photos and did my best to explain how I went about it but I'm no mechanic and stuff something up you'll have to get it done at the mechanics anyway .

I replaced the top one a couple years ago,it's definitely at the back.
Hoping someone has some info on it for me.
Cheers for the reply though mate.
