Manifold pressure transmitter

Hi, working on my RV10 firewall forward and was wondering if there is any reason not to use the third set of ports on the VA-168 sender unit for a metal manifold pressure transducer and connect to cylinder 6? Instead of the van’s manual which has it aft side of firewall and off cylinder 5?

AS Flightlines has a kit to move the manifold transducer to this port for the IO-390. Not sure why you couldn't do it for the 540.

Thanks. I understood is if the tranducer is plastic it should be aft of firewall but if metal can be foreward

Sorry, I haven’t heard that before, but I’ll have to look into it now as 2/3 of my transducers are plastic.

That is not universal. Many plastic parts are able to handle engine bay heat. It is all about the plastic used and that should be reflected in the specs for the part.
 
I have the TS Flightlines FWF hose kit, which is excellent workmanship BTW, and what you state is what I am planning to do, placing the transducer on the third port of the manifold, although I will use the port on Cylinder 5 as the hose was cut to for that length. Tom over at TS Flightlines is awesome to work with too, if you have a problem.

John, we can asssume that you have the Dynon plastic 'box' sender. YES it can be mounted on the firewall. Not, it doesnt have to be mounted near the brake reservoir, although its ok there. YES even if you have PMags, it can still be done. MANY ways to accomplish this.

I have the standard aluminum sender unit mounted on the left front of the firewall. Two of the ports are used for the oil and fuel pressure transmitters as per vans instructions
 
I was thinking of using the third port on the van’s stock sender unit which is made of aluminum
Just to clear up terminology - the Van’s thing with three ports made of aluminum is a “manifold” - to which you mount “senders” (or transducers, sensors…whatever you wish to call them). Many (most?) of us use the manifold, and use the three ports for oil pressure, fuel pressure, and manifold pressure.
