Here's how it works... As soon as a List member makes a Contribution through the Matronics Fund Raiser web site, they will instantly cease to receive these Fund Raiser messages for the rest of the month! Its just that simple. I really do appreciate each and every one of your individual Contributions to support the Lists. It is your support that enables me to upgrade the hardware and software that are required to run a List Site such as this one. It also goes to pay for the commercial-grade Internet connection and to pay the huge electric bill to keep the computer gear running and the air conditioner powered on. I run all of the Matronics Email List and Forums sites here locally which allows me to control and monitor every aspect of the system for the utmost in reliably and performance. Your personal Contribution matters because, when combined with other Listers such as yourself, it pays the bills to keep this site up and running. I accept exactly ZERO advertising dollars for the Matronics Lists sites. I can't stand the pop-up ads and all other commercials that are so prevalent on the Internet these days and I particularly don't want to have it on my Email List sites. If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email Lists, please make a Contribution to keep it that way!! http://www.matronics.com/contribution Thank you!

When I first started flying it (about 15 hours ago) the fuel pressure read about 26 psi running on the engine driven pump and would go to 27 when I switched on the boost pump. The pressure produced by the engine's pump has slowy been decreasing. It now shows about 24psi and even 23psi once. Turning on the boost pump always brings it back to the 26 - 27 range (after a brief surge up to 35 or so). The engine seems to run OK either way. So, I think the pressure sensor is OK. Is it normal for a fuel pump to sag a little in the first 15 hours of operation, or do I have a nascent problem on my hands? Does any one know the miinimum fuel pressure that AFP needs? Thanks, -- Tom Sargent, RV-6A ________________________________ Message 2 _____________________________________ Time: 09:21:32 AM PST US From: wgill10@comcast.net Subject: Re: RV-List: AFP and fuel pressure and fuel pump Tom, I occasionally experience the same problem, but it seems to be related to h aving full tanks -- perhaps the fuel vent line is full of fuel causing the pump to work harder. If I switch tanks, the pressure returns to 25psig. Aga in, it only happens with full tanks and usually lasts no longer than a minu te or so...been that way since first flight almost 800 hours ago.

You are still within limits with 23 PSI. I have been flying for 8 years with a Bendix system and I don't ever get the same reading from flight to flight. I don't recall the minimum fuel pressure, but the answer should be in your Lycoming engine manual. It is not what AFP needs but what the engine needs that is important.

Capen" Subject: Re: RV-List: AFP and fuel pressure and fuel pump Tom, Here's what I see on a regular basis (2yrs approx 90 hrs): Startup is about 17 or so but builds to 30 pretty quickly and then stays there - boost pump takes it to 33 or so and I've seen it fade down to 29 but come back to 30. You may be seeing an electrical resistance increase due to heat where the sender is mounted. Make sure the sender sees a good ground path. My thoughts, Ralph RV6A N822AR @ N06 - AFP on my XP360 - SJ cowl...just back from paint. -----Original Message----- >From: thomas sargent >Sent: Nov 3, 2010 11:43 AM >To: rv-list >Subject: RV-List: AFP and fuel pressure and fuel pump > >I have the AFP fuel injection unit on my RV-6A and a VM-1000 to monitor the >fuel pressure.

I have been flying mine for over three years and think maybe it was higher in the beginning. I wouldn't worry about it=2C just monitor it and have a good time flying. Only other thing I might suggest is remove a nd clean the sensor and see if that makes any difference at all.
