Not sure what you have going on but it sounds like a restriction or blocked hose.
Did you plumb it exactly how it was? Cause it sounds like you tried to dead head the pump. Which would happen if you mixed up the inlet of the valve and a work port.
Those other two hex plugs....one is a check valve and the other is the unload valve. They have to do with how the pump operates in two stages. And don't want to bore you with the details.
Also....it looks like you used Teflon tape. In general ...avoid that for hydraulics.
But for starters ...take a step back and post a picture of all the hoses you replaced....and where they are going to.

I think the hose from the pump should go into the side of the valve and the long hose going to end of cylinder should go to top of the valve . Ie. Those two hoses should switch positions on the valve.
hopefully someone else will confirm or deny this.

Yes, your hoses are mixed up.
The two on the top should go to the cylinder.
You are deadheading the pump with no return path.
The sides of the valve should be the supply and return.
Hopefully you didn't damage the pump and it's just the seals that blew out due to hose mix up

You can tell the story however you want, but the hoses are wrong

Look at the longer hose going to the cylinder.
What are the letters in the casting?.....sure looks like "IN" to me.
Which would need to be the hose coming from the pump. Which is also the side that has the adjustable pressure relief on it.
The side you currently have coming from the pump is the tank. Since you have the pump feeding the tank port. The pressure relief activate which is why you damaged the pump.
And again....the top two ports go to the cylinder.

I took a second look. The pump I thought looked like the tank.
Didn't see the hose clamp on the return.
Still same principal....pump feeding a work port is a dead head with no relief.
Looks like you only gotta swap the two hoses. Put the pump hose on the side and move that long hose going to the cylinder up top
And try to avoid the Teflon tape. Either use paste, or even better is loctite 545

change the hoses and see if it pukes oil, if it doesn't just move on, you have nothing to loose, unless there is metal in the fluid.
