Hi All,

I bought this fuel pressure tester at my local O'Reillys for $30, but the size of the connecter is too small for the 964's 3.6 injector rail test port.

I have read that Actron sells an adapter, but I am uncertain what size port we have.

Is it a 12mm x 1.5 or 14mm x 1.5? or something else?

In THIS diagram, part #7 is where you connect the tester. Say it's 12mm x 1.5. Actually say 12 mm x 15.5, must be a misprint.

Make sure you have plastic cup or rag to catch ball#8 on that diagram. Those ***** like to find good places to hide

I've wanted to do this on my car as well. If you could post a DIY that would be helpful...I've not done it yet, but have always wondered and since I have six cars here, would be fun to see the differences btw them all...

I can confirm, the thread size is 12mm x 1.5mm thread pitch. I will be testing my cars in a few weeks. I just purchased the "master fuel pressure test kit" from Harbor Freight. It has the correct size adapters.
