Hello 912 users

Does anyone know where to install the fuel primer lines on the 912UL?  I've read all the past posts on proper starting procedures and how a primer isn't necessary but I'd like to put a squirt button in my KF anyway. 

Thanks

Please post results when you get this sorted. I'm interested in doing the same for mines.

If you have a gascolator, you can run the draw from that point to the primer, then run a line from the primer to a T fitting then to each carb! thats how I have mine set up.

Luis,

The primer line as far as I am concerned is necessary. Every engine that we

have installed this on has started every time on 2 blades or less. If you

think about it that is a great improvement.

Under the carb if you look close there is a barbed fitting with a screw in

the middle.

You will need to split t0 both carbs and this creates a problem. At low

speed or warm up time the carbs are not flowing the same. So what happens is

one carb will suck all the fuel from the crossover line. If this line is

more than the normal 1/16 primer line it can cause the engine to stumble for

quite a time. Of course this would negate the primer.

I tried several types and sizes of primer line before realizing that the

aircraft world had already been through this.

I use a short stroke aircraft primer and this is enough, but any aircraft

primer will do. 

After you split (as close to the engine as you can) the line and run to the

carbs, I put a 20 thousandths safety wire in the end, hanging out and

sweated solder into the end. After the solder is set, I pulled the safety

wire out and now I have a 20 thousandths nozzle.

I push the line up and into the barbed fitting just flush with the carb

inside. A 1-inch piece of fuel line clamped to the barb and the line holds

it in place.

I can not push hard enough on the line size, it really does matter.

I'll take your advice and restrict the primer lines at the carb.

Thanks for the info.

One final note from me.   I managed to drill a .025 hole through the center of the 3.5mm screws that plugged the carb primer fittings.  Then the head of the screw was filed down so the diameter matched the O.D. of the brass barbed fitting.  The jets screw in nice and tight and the poly primer lines slip on normally.
