I've got a 02 LB7 and me and a buddy are replacing the CP3 pump and noticed that the fuel junction block had some rust/pitting inside the part with the plunger and spring. We were told it needed to be replaced and just wanted to make sure before we dropped the $1100 they wanted for it. Any help would be appreciated!!

 

Don't know anything about it but I sure wouldn't go on the advice of the guy sellin the parts

 

you talking about the block that has the fuel pressure relief valve andfuel pressure sensor in it?

 

Yessiirr. Its got the alan head plug inside one end that screws out and it's got a spring and plunger with two holes in the end of it that seats inside the valve or whatever it is. It had a bunch of trash in it and a little rust. Didn't know what purpose it served or if I needed to completely replace the entire block and regulator. Was going to get a new press reg either way. Just never heard of anyone replacing it before and it costs more than the damn CP3 pump. Thanks man
