914World.com _ 914World Garage _ An accurate fuel pressure gage

Posted by: 76-914 Jan 10 2010, 09:39 PM

I know how to adjust my fuel pressure but I don't know if my Harbor F FI tester is accurate and it seems to working OK so I didn't want to touch it unless I was absolutly sure of the gage accuracy. Maybe someone here in the IE would be willing to host a workshop where several of us could check our fuel pressure one Saturday am. ??????????

I checked my HF one to a known gauge. Within 1 PSI. Even "good" gauges aren't very accurate. We buy LOTS of gauges at work and have to send even the new ones in for calibration. Seen them off 10 PSI on 300.
