Thx lucky Mike, will use mirror and light while holding plenum down to look for leaks. Would imagine fuel could be smelled if leaking when plenum held down as well?

I have ordered manual discs online for future use, but would like to check fuel pressure with my fuel gauge/attachments prior to discs arriving.

Not sure where to hook up gauge and/or if this also requires a special MB fuel pressure gauge to check?
