Fuel Primer Solenoid Valve Location
 
I'm looking for suggestions / pictures on where and how to mount the standard Vans / Aircraft Spruce fuel primer solenoid valve 05-29823.

No idea on location, but I applaud your correct spelling of solenoid. I think it was around 1975 the last time I saw a builder spell it right. :D

Here's where I put mine. This position allowed me to mount the bracket securely on the firewall stiffener. Also notice the lock-wire for just-in-case.

I fabricated a simple bracket to mount the solenoid.

Fuel Primer Solenoid Mounting Location
 
I know it's been a while since this thread but I'm trying to determine a good location for the primer solenoid. I am thinking of mounting to some point on the engine and connect a flex fuel line from the firewall mounted gascolator. Then run the copper lines from the solenoid to the cylinders My thought process is to minimize vibration of the copper if it's run from a firewall mounted solenoid as has been recommended in the past. Since I don't have a vacuum pump installed, my thought was to fabricate a mounting bracket for the solenoid and attach it to the vacuum pump pad. If anyone out there has this or similar installation, I'd appreciate a few photos. Thanks in advance.

I understand you?re concern about vibration breaking primer lines, ( had one break on my Skyhawk that had no engine monitoring to alert me to a lean cylinder) when I installed mine I put it right next to the gascolater since there is only fuel flow in the lines when power is applied to open the Solenoid , I put a vibration loop in the copper line before T?ing off to # 1 & 2 Cylinders
In your scenario you?re putting pressurize fuel up to the engine in a expensive limited life fuel line unnecessarily , my 2 cents , cheers

Why copper ?
 
TS Flightlines will make a small flexible line that ?won?t break?. I machined a simple bracket for the solenoid to clamp to the mount close to #4 cylinder to keep the hose short. Fire sleeved fuel line from gascolator to solenoid should endure the application. None of my business, but is there a prefilter before the boost pump to protect it ?

Old post, but I'll throw in my 2c.

I used a SS braided line from firewall to a distribution block on the engine. From there it is copper to 3 cylinders.

yes to your question. Fuel from the Andair selector passes next thru a filter, then the boost pump, gascolator, engine driven fuel pump, red cube, then into the carb. The Andair gascolator has a port for the primer coming off of the top of it.

thanks for the photo. I think I saw the same pic on Google. Q. Did you fabricate your own distribution block? I considered this approach also. thanks.
