those fittings are known as 'Compu-check' fittings. Snap-on and a few other vendors have fuel pressure test kits, etc. that have those adapters and gauges needed.


Mechanical gauges or not ... you need also to FIRST check fuel pressure reading in in Insite while cranking. You could have pressure, but if that ecm does not see above the minimum required, then it still will not open any injectors to let it fire any cylinders off.
