Viking Aircraft Engines replied to Phil Cook's discussion 130 Cooling system capacity
"1.5 gallons. No need to fill the system to the max with prep fluid in order to absorb any moisture."

John Heather replied to Phil Cook's discussion Viking 130 shutdown by shutting off fuel pumps?
"Yes, I have the bleed-off line from the check valve going back into the Large Header Tank on my project. Mandatory I think.

Agreed, electrically killing the engine in flight (for whatever emergency reason) causes EFIS, radio and flaps to go out(my…"

Phil Cook replied to Phil Cook's discussion Viking 130 shutdown by shutting off fuel pumps?
"Thanks John. Always good to hear real-life results and experiences. Do you have the bleed-back line from the check valve manifold to the header tank to relieve pressure in the lines after shutdown?"

John Heather replied to Phil Cook's discussion Viking 130 shutdown by shutting off fuel pumps?
"Hi Phil, on my 130 engine (during testing of the ECU's ability to recover from low fuel pressure), I remember it taking a full 60+seconds for the engine to finally splutter and stop after switching off the low pressure pumps in the Header Tank - so…"

Loren Warner replied to Phil Cook's discussion 130 Cooling system capacity
"Been awhile since we added coolant, so I don't remember. Since you're planning to use Prep anyway, you might as well just fill with water, and then drain to measure the capacity."

Phil Cook replied to Phil Cook's discussion Viking 130 to Garmin G3X Touch via CAN bus
"Got it - the CAN bus from the ECU only exposes the core engine data, not the things we're really interested in (gearbox temp, fuel pressure, oil pressure, etc)."

Phil Cook replied to Phil Cook's discussion Viking 130 shutdown by shutting off fuel pumps?
"Well, this wouldn't be starving the "light" pressure pump, it would be starving the high-pressure pump; I think that's what you meant? But I understand - your stance is to shut down the engine by cutting power. On the depressurization of the…"

What is the liquid capacity of the 'stock' 130 cooling system (with the standard radiator)? I know there will be slight variances based on the way it was plumbed but I'm looking for real-world quantities. I received one gallon of Evans prep fluid…

Viking Aircraft Engines replied to Phil Cook's discussion Viking 130 to Garmin G3X Touch via CAN bus
"We do have an interface box (Data Logger) that will read this and also record every flight on an SD card.

It is less useful to push this info to any EFIS since most of the info is not useful for the pilot.

Things like cam position and ignition…"

"Starving the GDI mechanical pump for fuel is not good and can make a restart harder

Shut down the engine by cutting power to it."

"Phil, shutdown of ECU, as my ECU white conductor was labeled "battery power always on" and the white red conductor was labeled " switched ECU power" I wired as noted. The wiring diagram dated 12/12/2018 shows these conductors (W & R/W) wired to…"

Phil Cook replied to Phil Cook's discussion Viking 130 shutdown by shutting off fuel pumps?
"I just saw Jan's response to the "A Neeewwb Question": "The issue in regards to shutting down the engine with the “high” pressure fuel pumps is that you would starve the “higher” pressure mechanical pump and empty the fuel rail of pressure, making…"

Phil Cook replied to Phil Cook's discussion Viking 130 shutdown by shutting off fuel pumps?
"Another benefit of this approach might be that the master switch can remain on while shutting down, leaving the lights or other ancillary devices on as desired. Also, with the fuel system emptied then maybe there's less danger of inadvertent…"

Viking Aircraft Engines replied to Phil Cook's discussion High pressure fuel filter
"Just saw an installation with a combination aluminum tubes, fuel injection hose and AN fittings. A complete mess and dangerous. The engine uses 5 /16 barbed fittings and the same with the pumps and filters. There is a big difference using braded…"
