True but just because it holds pressure doesn't mean the spray pattern or volume is correct, does it?

Thanks. Figured I didn't have to, just wanted to be sure. It leaked both ways.

But lets say it does or doesn't, why do you want to keep the junk? Why waste time diagnosing bad junk? If I am worried about a leak and I have fresh injectors, I know it probably isn't them and can go on.
