Advice around a leaky injection pump on 1hz (1 Viewer)

[Bcg1976]

Trying to get away with not removing the pump. Popped the top off, replaced the top seal and washers for in and outlet.

Put back together and now for the life of me i can't get this pump to prime.

Primer isn't spongy, have cracked the outlet and run diesel through it. Still no good.

In the end I gave up and took the top back off again and turned the engine over to make sure the pump was operating. Video attached.

The bubbles appearing don't fill me with confidence. Any suggestions?

I'm still learning diesels.

The outlet of the pump? Or the outlet of the filter housing?

I had a similar issue after replacing some seals and it turned out to be an air leak. Re-torqued everything I replaced and it fixed it. Some good info from some smarter folks in the thread I posted when I had the problem 1HZ Injection Pump Question - https://forum.ih8mud.com/threads/1hz-injection-pump-question.1349432/

Probably sucking air through the filter housing. Bypass it to see if that's it. New fuel filter assemblies are cheap and easy to swap out.
