How to test fuel pressure?
I'm having some issues with my tune and I'm trying to run through some diagnostics. I've ruled out pretty much everything I can but I need to check my fuel pressure (not the high pressure rail, I know there's a sensor for that already). Does anyone sell a part to tap into the fuel line to add a sensor? I've looked at the portions of the shop manual posted online but they don't really seem to include diagnostic techniques (which would usually call-out any special tools the dealer has access to).
If there isn't a ready-made solution can someone provide the fuel line connector specifications so I can piece together a system from fittings, T-s and adapters? -Matt |

I think you have the right idea with cobbling together your own stuff. That's pretty much how the manual specifies.

I created a DIY post on the setup I finally settled on. Hopefully it will help someone.

I use a @DeliciousTuning MK1+ FF kit, which has an in-line fuel pressure sensor for monitoring pressure from the in-tank pump to the port injectors.
