Can you elaborate on this post???
I was thinking of setting one at 5p.s.i. And putting it on the return to tank line AFTER the returns come together at the back of the block.
Still a nogo?

Only thing that is post filter is the the rear most port which has the vacuum canister for the filter light.
You don’t want to restrict the return of the injection pump, worse case scenario it won’t even start, otherwise you will be limiting the amount of fluid cools the pump and injectors.
The valves can fail, but more than likely it’s a piece of old shower head that could be sucked up into the line. You can unhook your feed line and blow back to tank to be sure it’s clear of debris.
