Fuel pressure test port?

Recommended Posts

Hi guys, yes I've searched and can't find a darn thing! I have an 08 LGT and I'm trying to monitor fuel pressure to help diagnose a stumble under load. Is there a port somewhere on these things that I can attach my fuel pressure check gauge to or do I have to cut lines and "T" in??

So all that is needed to be done is tee into the feed line after the reg? Warm up the engine and the. Test under throttle? Or do you need to actually test this while driving? My tuner wants me to test fuel pressure relative to manifold pressure 1:1 at full throttle
