Injector pump leak.

[Mass Ownage]

My pump is leaking out of the top where two of my injector lines connect to the pump. First I though it was old lines so I replaced them all with a new set. Still leaking from the same two lines. One did get better but still seeps above idle. Is there an easy fix or am I basically stuck changing the pump?

Have you tried a 12 point line wrench crowsfoot?

What did you torque the injector line nuts to?

Yeah I used I line wrench crows foot.

A typical place for the HH to crack is between the line ports.
Clean it real good, push the water caps up, dust it with baby powder and run it.
See if the leak is not between the ports and not at the threaded connection.

Replacing the hydraulic head isn't too terribly difficult. If you can get the injector lines reinstalled correctly . Look up how to time the quill gear correctly, remembering the centrifugal advance will bump the timing and the quill has a window which allows for only one installation position.

Took all the lines back off, recleaned all the ports, reconnected lines and was able to get #5 to stop leaking and #4 stopped at idle but still leaks a little under load.

Also, how tight is the middle bolt on top of the IP? I had a breaker-bar on it and couldn't loosen it. I didn't want to break anything so I stopped.

Seems to be an epidemic of leaks on these IPs here lately. Hope you can post some pictures of where yours is leaking.

Took the lines back off and recleaned all the ports, even ran a small magnet on a stick in all the ports and flushed them out with carb cleaner, and reinstalled. Haven't seen a leak from the lines, but now I can see I have a leak where the HH mates with IP. Project for this weekend.....

Half the time I don't know if it's a new post or an old one that's been resolved. Seems to be a couple a week now.
