I have the Precision Airmotive EX-5VA1 fuel injector. The flow divider
on top of the engine has a nozzle with a cap on it. At this point, I
don't know it's function but at some point, someone I trusted told me
that the little black cap on the nozzle should be removed.

I noticed that there is a blue fuel stain around that area and am now
wondering about the function of the nozzle (vent), whether it should be
capped, etc.

I see a mechanic tomorrow for some consultation but would welcome any
insight.

PS, I'm thinking very seriously of attending the Airflow Performance
fuel injection class to get a little smarter about the system and to
tune for lean of peak. Anyone done this? Worthwhile?

Thanks

Bill Watson

I haven't attended, but everyone I've talked to that had attended, spoke
very highly of both Don and the class. The other advantage is that you have
an opportunity to get your injection system balanced. I am planning on
attending as soon as I'm flying.

I'm pretty sure that "nozzle" is the same as in my standard set-up, and it's a fuel pressure pick-off point. Since Van's pulls that closer to the pump on their setup, that should be capped off permanently (AN fitting).

That port is for measuring fuel pres like Dwight said. Fuel pres at this point is converted to fuel flow in some applications. If you have a new Lyc you had to remove an 1/8" plug, just use that to plug this hole. Use appropriate sealant.

Lean of peak - is that the procedure where one converts fuel savings into profits for cylinder/valve manufacturers ?

No, Lean of Peak is the procedure where one converts profits for Oil Companies into more flying time for RV-10 owners. It's a really cool process!
