Any potential buyers should bear that in mind. That said I've had hours of fun with my Jab and know it intimately. The core engine is great and now I have 5th generation heads on it I think it's quite sorted. So I'll consider a UL power unit in about 6 years.....

From: "DaveG601XL" Larry, The fuel pressure transducer should be placed between the engine fuel pump and the carb. Cap off the primer port on the gaslocator. Unfortunately I do not have a good picture of my fuel pressure transducer. Attached is the best I have. I mounted my oil recovery bottle on the right side motor mounts by way of sheet aluminum and adel clamps. I mounted the fuel pressure transducer to the back of this mounting sheet using a big adel clamp around the transducer.

From: "Don Honabach" I have a 3300 on the older 601HDS with a Dynon EMS (FlightDek 180) which should be similar to your setup. Since ultimately you care about the pressure that the carb is seeing, I took the fuel hose from the output of the mechanical/engine driven fuel pump and placed a T connector in it and connected one end to the fuel pressure sensor (that I got from Dynon) and the other end to the carb fuel intake port. My fuel pressure sensor is located on the right side of the firewall (passenger side). I also placed the fuel pressure sensor at the same level as the carb - I don't understand this but I was told that if I was concerned about the pressure #s of the carb, that the fuel pressure sensor should be at the same level for the best accuracy. Be aware that the Dynon setup may not be the best for the 3300s. If I remember correctly, our fuel pressure needs to be between 0.75 to 3 PSI. The Dynon is setup for a sender that measures 0 to 30PSI and combined with the fact that Dynon doesn't include a zero'ing function in their software to handle starting at a true 0 point with the sensor your numbers may not be all that accurate for the range we need to measure (with any luck they'll update their software in the next version). Also, if I understand this correctly the idea is just to have a bit of positive pressure with the Bing carbs. If you have too much - over 3 PSI (?), you'll overwhelm the carb and have issues with fuel overflowing, etc. For what it's worth, I normally see between 1 to 1.75 PSI with just the engine driven pump running depending on WOT or cruise.

I kinda thought it would have to go in the line from the fuel pump to the carb but it never hurts to ask. I'm doing my oil recovery the same way so I'll just put it there.

From: "DaveG601XL" Larry, I agree with Don that there could be something better than a 0-30 PSI transducer here. I asked Dynon about a smaller one last year, but they do not offer one. The 0-30 does seem to work OK, but we are definately on it's low end. If you could find a 0-10 or 0-15 transducer that works on 5 VDC excitation and is compatible with engine compartment surroundings, it would probably work. I would go fly and not sweat it for now (I did). -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 Phase I flight test complete 10/16/08 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=225582#225582 ________________________________ Message 9 _____________________________________ Time: 11:55:20 PM PST US From: =?iso-8859-1?Q?J=E9rme_Delamare?= Subject: RE: JabiruEngine-List: Re: Fuel Pressure Sensor Location????
