These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My fuel pressure gauge says explicitly that it won't work with Bosch systems; so I need either 1. The name of a gauge that definitely will or 2. The specifications (and ideally a link) to an adapter that will work with a Bosch system and a "conventional" fuel pressure gauge. I just took delivery of an adapter that was supposed to fit and it doesn't, so back to the drawing board. Many thanks.

Use fuel pressure test port on fuel rail under brass cap. Its a standard Schrader screw on type valve access port. IIRR its a 1/4" male flare fitting. Refrigeration/AC gauge hoses fit it perfectly and ac gauge set will read fuel pressure. (not the 134a quick connects, use regular 1/4" A/C hose) . jmo

Thanks, I have a set of A/C gauges, I'll give that a shot. Appreciate it!

POST 4Original post

You need the old school R12 or R22 lines and the fittings need to have the pin to press the Schrader valve core. I have a tester from Harbor Freight which seems to work.

This is a source reference. Confirm exact model applicability in the original material.
