Isx high pressure fuel pump test.

[Hallmanhauling]

Raze,
On one of tour YouTube videos you checked the fuel pump head by pressing on the little pistons and them bouncing back in place. I have one that bounces back into the same spot. But the other will only come up about 3/4 of the way. And even less if I press it again. What was this a symptom of? Do I just need to replace the cylinder or the whole pump head?

check valves are toast in the pump head for that plunger. I usually change the pump head as trying to change the check valves is a gongshow.

I do not remember making a video of the pump head... Can you post a link to this video?

It was another person that made the video. Where can I order the high pressure fuel pump ? Thank y’all for helping me. Also does the new head come with the springs and items that . you are

The ReCon heads from Cummins come with the barrels, plungers, springs and actuator already fitted.

Do you know what the Cummins part number is? I have an isx 15 with the 2250

Never mind I found it on the Cummins website but they say it is no longer available

Give Cummins your engine number and they'll work out the head number you need.
