Fuel hose diameter from filter to rail?
Just got a fuel pressure/vacuum gauge to do some testing on my car and want to fit it up to the hose between my fuel filter and fuel line. I know I'll have to T the hose or buy some more for testing purposes, but what's the inside diameter of the hose that runs from the filter to the fuel rail?
Am at work now but want to try and grab some from the auto shop on the way home. Thanks for anyone that can help me out with an answer

I would T it going out of the engine.That way you know that the engine is getting Fuel(as the PSI will show that the rails and injectors have gotten their fuel).
If you put a Gauge before the engine,Ya sure,it will show that the engine is Getting Fuel Up to the gauge.But what about to the Injectors??.It won't tell you anything after that.(like if the injectors GOT fuel)..
so for that reason.put your Fuel Pressure gauge after the engine.
Btw,this is with an aftermarket regulator and gauge setup.

Need to do separate checks to find out if the injectors are working at all and getting fuel into the engine.
