Well.... I have. Thanks to CJ Motorsports, they have provided us with this handsome 2 bolt fuel tap with an 1/8" NPT port. AND I have connected a 100 PSI

AND I have connected a 100 PSI pressure gauge to it, allowing me to view the current fuel pressure and record it 10 times per second to the SD card.

The code should be done by tonight and tomorrow will be the first test.
Yes, I think this will be interesting...

Nice! Why is the gauge showing 62 PSI? Do you have modifications done to the fuel system?

Rev'ed the engine, and caught the spike in the pic just as the rpm's started to drop. Normally, it's about 54 at an idle.
