Ways to cure 7M oiling issues

ill check when i get home. i know its not the 0.5 he has. but for most 8an will be more then sufficient.
I dont know. Im not sure of the conversion between AN and inches but I wouldn't think 8 AN would be much bigger if any than stock.
AN - (dash) sizes are based on tube sizes they are. The symbol "-" (dash) is commonly used in the aircraft industry, when used in a sentence referencing drawings "Whats the next dash number?" you would be asking whats the next assembly? When used in a sentence referencing AN fittings you would be asking whats the next size of tubing/fitting.
AN dash sizes are directly related to the outside diameter of a tube and refer to 16th of an inch, so a -8 would be a 1/2 inch OD (outside diameter) tube. The inside usually depends (in the automotive world) on what material the part is made of, in the aircraft industry it is a very consistant number controlled by a military spec. Most of the -8 aluminum fittings I have seen are about 3/8 ID (inside diameter) obviously automotive fittings will vary because they are not controlled by a military spec.
I am still working on it (the tube assembly) I was at the machine shop until 9:00 last night. Waiting on one little piece. I might have photos tonight, sorry for the delay.

awsome thread guys,. i hope i can afford the extra cash to upgrade this area when i pull my motor back out for thr 15th time this year..
Yea I found that, just yesterday myself. The problem is I havent made sure the jamb nut wont force the fitting into the side of the oil pan.
Sorry for the delay on the photos, a few things came together and a few fell apart.
If you are going to use -8 why change it at all? Chances are -8 is smaller than the stock line.

the 8an doest have the crush bends in the tube. i doubt those bends on the stock pipe are the same as an -8. also, on the 5m, it has mor bends, and since i have it in a mkii, i have to use the 5m pump and pan. i may goahead and do everything on mine in 10 because of the power level im going for, but 8 should be sufficient.

That is a BSP 90 fitting.
I have the AN10 sized one on my pump. Not really sure it's needed, but that's where I ended up.
ARZ's tube setup appears to be a better deal however.
The pan clears it, and you can slightly turn the pump, and bend everything to fit with minimal issues.
Looks like this on the pump in place with the hose/fittings I used.

Ok I finally have a finished product to show you guys. These are made with .049 wall hydraulic tubing. After making the Aluminum tubing I found more than one source that stated that it wasnt rated for any more pressure than 50 psi. This new stuff is rated at over 1000 psi so I think you will be safe. To all of those that think they will try this by themselves, I say "Go Right Ahead" This was a total PITA!!!
You have to be right on the money for the width and the angles and the height. On top of that you have to miss the oil pan. I must have thrown away 20 feet of tubing trying to nail this down. Now I can see exactly why the factory line has that kink in it. That was were they got all of their tolerance from.
Now for some good news.
I should have parts ready to mail by Wednesday March 7th. BTW the theoretical minimum inside diameter is .527 which is quite a bit bigger than the 30% stated before.
Now for the bad news.
I havent been quoted a price on the tubes, I have a ballpark figure but no hard and fast quote. I can assure you that the price wont increase by more than 15%. I hope that this dosent push this product out of the affordability range. It is far superior than the stock component.
Sorry I couldnt bring my shiny motor down to the tube shop, sorry for the dirty motor photos.
Hope you like it

Anyone running the braided stainless steel line on their motor? That seems to be the easiest/least expensive option.

I'm still in .
Just to clarify things: There will no drilling and tapping in new threads like previous design correct? If so, it will not flow as much as you previously inteded, but it will still be better than what we had right?

Correct!!!
Incorrect! I fully intend for this to be better (bigger) than all the measurements I showed on my original aluminum tubed design.
