Normal reading is about 29 psi. part total time is about 450 hours. anyone else had sensor problems? I carry a replacement in the tool/parts box so I can change it but trying to confirm that it needs to be replaced. Engine continues to perform properly. ________________________________ Message 2 _____________________________________ Time: 10:41:10 AM PST US Subject: Re: RV10-List: fuel pressure sensor From: Rob Kochman Don't know if it's the same sensor, but my one from Dynon lasted about 25 hours, before it started "oscillating" with the boost pump off. Replaced it, and the problem was fixed... for about 5 hours. Seeing the same issue again.

I checked with EI and found that we are "locked in" to VDO sensors check for pressure. I did replaced egt probes with EI and have had no further problems with egt probes burning /disintegrating. http://www.jegs.com/p/VDO/VDO-Pressure-Senders/887192/10002/-1 ----- Original Message ----- From: DLM To: rv10-list@matronics.com Sent: Tuesday, May 24, 2011 10:17 AM Subject: RV10-List: fuel pressure sensor I have a GRT sensor which is occasionally providing a reading of 38 psi which puts me into the out of limits condition for the Chelton displays.

Dynon gets its ground through the block bolted to the firewall, so it that is somehow isolated or not making a good ground, that could possibly be causing it.

Both sensors started giving erroneous high readings intermittently in my Cheltons and on Vertical Power. Sandy at GRT says this is pretty common with this sensor. It is a five minute job to swap sensors, but it is a PITA when it starts giving you false alarms. I changed the first one at approximately 175 hours, and this recent one at about 350. I can't remember the cost, but I think it was in the $35 to $45 range.

You can take the DB-25 connector shell apart and lay the cable alongside and fit it through about a 3/4" - 1" hole. After getting it through, just replace the shell.
