914-6 GT oil line specs, WTF (W hat's T he F inal) opinion on size of front cooler lines Options

[forrestkhaag]

I am wondering if anyone has a good spec on the ID/OD for the two brass lines running to and from the front oil cooler? See Pix from P-Base for reference / I will be using AN fittings at the working ends for my flexible connections to the cooler and the thermostat and oil tank etc.. And does anyone know generally what the oil pressure is (hot) going to the front oil cooler??

I could also makes kit-sets for other installations if anyone is interested / Once I know how the factory did the job and I can accurately replicate the same or similar quality and product.....


Thanks in advance for the input.

I have a slightly related question:

Can I use 5/8" Aluminum tube (10-AN like this: https://www.summitracing.com/parts/sum-g2558/overview/)

for high pressure (up to ~100 PSI) oil lines?
You can flare the tubing and add AN fittings.

I was wondering if I could replace a maze of 10-AN fittings and braided stainless hose with some of this.

I know that Al Tube is acceptable on aircraft for oil, but is it a different type?

I have some of that line. Not bad stuff, but for an oil line that's WAY too small. You will also need hose ends for vibration purposes on each end of that since that tube is super rigid, and by the time you're done you have about DOUBLE as many AN fittings as you would have if you had just used hose.

(IMG:style_emoticons/default/hijacked.gif) First sorry to Hijack, I wouldnt mention it but I am curious what keeps more people from using hand bent metal tubing for these applications.

I currently have 12AN Aramid/steel braid flex lines lines running from the engine bay pass side through the heater vent hole to the front for oil coolers and back (almost 35 feet total in the loop).
The 12AN then gets necked down at a bracket on the engine front cooler housing to 10AN.
The 10AN then goes into/out of the engine at a cooler blockoff plate that has 3/8" NPT fittings.

So what I would like to know basically is: If I can build it out of 10AN fittings and SS hose, can I then just duplicate the plumbing using bent Aluminum tubing and flare nuts?
Could I use a roll of Al. tubing to run from the front to the back like the copper/brass?
What are the drawbacks?
One I can think of is metal tubing might fail more catastrophically where the hose is more likely to begin to leak enough to be noticed before giving up?
