help ID part on spool valve prior to removal

[animals45]

hey folks & a Dinoil 2 spool valve on the TnT kit on my 3301HST . I have a leak that looks like its coming the " Main Relief Valve " It's to the left of the left spool valve . Is this the proper name for this part ? If I remove the part does it come out in one piece & then I can replace o-rings/quad rings of the assembly ? It's to the right on the side pic of the " IN" marking on the body .
thanks

Thats the inlet pressure relief. Different valves use different types. It looks like its a cartridge type relief but might be anything. Have you tried tightening it up?
