Attempting to measure fuel pressure on TBI...

[Dshow]

I'm trying to measure the fuel pressure on my 2001 Mercruiser 5.7L Throttle Body Injection. I have an adapter made for a GM TBI and I was planning to put here here:

But when I got the fuel line off, both connection are the right size, but appear to be the wrong type.

Does anyone know the part number of the correct adapter or how can I make this work? Thanks!

Don?t know how to make yours work.
The Mercruiser numbers are
91-18078 has a barb fitting
91-806901 has a Schrader fitting
They look like yours but fit the throttle body you have
Good Luck Muc
