Rebuilding Detroit

That check valve is the one I'm referring to, guys will just spit out knowledge they hear on the interweb without actually knowing what they are talking about.

The check valve they are referring to is a pressure regulator on the ddec v and a check valve. It's only a check valve on the older ddec which is why so may guys don't take that regulator into account when diagnosing low fuel pressure on the ddec v.

Also the bull gear, everyone on the net will tell you its such a big failure point, that's not true on the ddec v but guys online don't realize that because ddec iv is the commonly talked about engines and we all just pretty much regurgitate info we've read online.
