1999 K2500 Suburban - Hydroboost leaking, replace or upgrade?

I left the lines attached.

Also, +1 on the filter, I should do that too. I'd done a full purge on the PS last year and I still found this in the HB.

Red because I dumped 2 bottles of Lucas in an attempt to kick the can on fixing the leak until I got home.

I left brake lines attached. I removed steering lines.

Id be putting a magnetic filter in a hydroboost system 100% just because it has a fluid loop from a pump which esp aftermarket ones often arent high quality and metal debris can quickly start circulating with pump failures or defects or high heat and wrong fluid choices etc etc.

what kind of pump you got? Regular saginaw with the hydrboost reservoir? is the flow control valve from your original pump or is it the one that came with it?

excess GPM and pressure do one thing when you account for time and miles.
wear the things they circulate through. especially if its got metal.

I don’t remember which style pump it is. I never did anything for flow control valve so have no idea about that.

Anyone have any updates on this issue? My new-to-us crew cab just blew a seal in the hydro boost,cause it's not leaking from the lines. It just dumped fluid in the driveway,and lost steering assist ( not fun at all on this big truck!).

Likely the same seal I esploded on the dually, start with post #718.

Yeah 125kpa at 2500' and 125kpa at 700'. Something is up. Even so it hits hard at 125. It blows the lid off of the timing table, so that boost timing puller is handy on the custom operating system. The custom OS is a must when playing with boost, thats for sure. But yeah something has to be up...
