Trim cylinders leaking down

[cameron92]

How can I pinpoint where the pressure is not being held, drive will fall completely to the ground in about 5-10 mins.

I ordered 2 cylinder rebuild kits but now I'm wondering if those are even needed, could the leak be happening in the pump? Where do they commonly leak?

The only way is to get a pressure gauge that reads up to 3000 psi and connect it directly to the high pressure discharge port .i know it takes some creative plumbing. NAPA sells 3/16” made up steel tubing with flare nuts in short lengths. You will have to get the fittings to mate to the gauge.
