I have went through pump with orings and relief valve and new lift piston and rings...a lot of water and sludge..lift worked ok before i did it but it sure needed the cleaning..question,i installed a 5000 psi gauge to see if it checked out...with nothing hooked to 3 point hookup no pressure showed on gauge till it was at very top.had 3000 and relief bought it down to 2700..didn't leave it there long...should you adjust the top stop down so this wouldn't happen if you pulled the control all the way up..have never checked one with gauge but looks like it would be bad to have full pressue all the time in travel setting...i adjusted top cover settings and everything works to my liking but this don't seem right but i don't know
