HPOP Pressure Test

Where can I connect a gauge to test the pressure of the HPOP and how high does the gauge have to read to?

Hydraulics shop should have a gauge for what you need. At least 3000 psi. You have AE correct? Are you suspecting ICP?

You can connect a gauge in each head via the ports in the heads. Just remove the plugs and use #5 ORB adapters to what ever your gauge is. These are the same plugs that get removed to install the HPx cross-over tubes.

Can also disconnect the HPOP hoses off the heads and use adapters (Eaton STC type) to connect a gauge directly to the pump. You can crank the engine and read pressure. You should make sure the gauge is capable of 5,000 PSI. The system can easily hit 3,000 psi.

HPOP Port

How about the port just inside valley from the #1 and #2 injector. Isn't that the HPO galley?

I want to make sure my HPOP is good because I suspect everything.

Yes I have AE and am just learning to use it. Will it show HPOP pressure?

Yes, AE will show HPOP Pressure. Use the live data meter to show Injectior Control Pressure.

Here is a article to help. HPOP Health Check

If you decide to use hoses and fittings, be careful. All of the parts must be rated to 3000psi or above. My truck has 300,000 miles, and the hpop gets around 2500psi.......Have a great Turkey Day....:-)

Ken's right. IIRC, the relief pressure of a good hpop is ~3650 psi when it is deadheaded. When working with hydraulics, there's no overkill when it comes to safety.

HPOP

I will take a shot at using the AE to check the pressure before I mess with hoses and gauges.

thanks for the concern
