racin4ds Posted May 16, 2018 Share Posted May 16, 2018 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?? Link to comment Share on other sites More sharing options...
utc_pyro Posted May 16, 2018 Share Posted May 16, 2018 There isn't a port, you'd have to tee into the fuel line. Link to comment Share on other sites More sharing options...

relative4 Posted May 16, 2018 Share Posted May 16, 2018 No need to cut anything, just disconnect the line coming out of the FPR and tee in there. Procedure and specs here: http://people.csail.mit.edu/ilh/vacation/ Link to comment Share on other sites More sharing options...

Ares3985 Posted September 12, 2019 Share Posted September 12, 2019 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 Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
