Hi All,



The Van's RV-10 wiring harness kit is designed for a carbureted engine with a boost pump.  I'm

installing a fuel injected engine so need to make some modifications.  It looks as if the easy thing

would be just to install a 10A breaker and upsize the wire to convert the boost pump circuit to a

injection pump circuit but is that really what is best?  Seems to me we want that pump running as

long as the ignition switch is in a run position and not switched with the master on/off.  Like to

hear what others are doing.

Thanks

The kit comes with (or at least used to) a switching breaker (5A) for the

boost pump.  For Injected engines, you need a 10A.  You can just switch out

the breaker and change the size of wire, if necessary, based on the amperage

and the length of the run.  You don't ever, that I can think of, need the

boost pump when the master is off, and you mainly just use it for startup

when the master is on, of course.  You definitely do not want to run it all

the time when the ignition switch is in the RUN position.  Just a breaker

would certainly not be the way to go, even if it is a push/pull breaker.

You want a switch, but again, that is what the kit comes with.  It just

happens to have the breaker in the switch as well (switching breaker) to

keep things simple.

So I think you are telling me somewhere on the large lump in the corner of the shop (aka io540) is a

mechanical fuel pump and the electric one is just a backup?  I guess I better read that stack of

manuals and ask questions less....



I guess I've missed a step in technology between carbureted C150's and EFI where everything is

electric.



Thanks,

Oh yeah!  I find it amazing that the Feds keep harping on safety .... 
	


safety .... safety ..... and yet they still prevent a certificated 

aircraft from enjoying the technology advances since the stone age.  I 

really believe that electronic ignition (EI) coupled with electronic 

fuel injection (EFI) would be a huge step forward in making our engines 

more fuel efficient and prevent high cylinder temps on takeoff etc.  EI 

would eliminate fixed firing advance and EFI would take care of the 

changing mixture requirements.  But, I guess I tend to dream too much.   

Maybe when I have more time to fiddle .....

The Feds are still in the stone age when alternators/generators lived extremely short lives and batteries tended to discharge fairly quickly due to the high draw from old-style electronics. Modern EFI systems have minimal draw compared to landing lights, etc. Batteries today have AHr ratings for the wieght unheard of 30 years ago. There's NO REASON for not using electronic engine monitoring/management.

Why would the fuel injected engine require a different breaker size for the

boost pump?

The carburated fuel pump is a Facet Pump and the injected engine uses an 

ES Airflow fuel pump.  Thats the difference, but I do not know if there 

is any difference in power requirements.  The electrical design per 

Van's wiring diagram calls for a 5 amp toggle switch breaker with 18 AWG 

wire.  And no note for a difference between the 2 pumps.

I don't know why, but the pump for an IO requires more than 5 amps.  When

talking to Van's, they said that the kit was for the O engine, not the IO,

so I would need to go with a 10 amp switch.  Again, I don't know why, but I

know it is true.



Do not archive.

The Facet pump for the O series carb model draws only 1 amp according to

Suspect the higher pressure OI pump would take a little more oomph!

If your installing the Airflow Performance boost pump P/N 3090050, you will require a switched 10 amp circuit.  We recommend a 10 amp breaker with #16 gauge wire minimum to supply the pump.  The pump will draw 5-6 amps (at) 30 PSI and there's a little inrush current on start up thus the 10 amp breaker.
