Hallo,

i've read that most of you use 3AN oil feed line and 10AN return line...
but whats unclear to me is, is this the diameter of the tube or is this the minimum diameter on the whole line?

because you have to use something on which you put the tube on, to fix it on the oil pan for example!

so maybe someone can measure the minimum diameter of his 10AN and 3AN line?

Thanks very much
Malte.

 

if you are asking the tube size for the return, it will be 5/8ths. -10 = 5/8ths.

No, please read, i'am not asking for the tube size, i'am asking for the minimum diameter in a 10AN Oil return line and the minimum diameter in a 3AN oil feed line...

NOT the tube size... i need to know the diameter of the hole inside the fitting.

 

Don't get mad at us because no one can understand your poorly worded question, jerk.

And the opening in the fittings is the same size as the line; it doesn't taper down.

Sorry but if you could read the single word "minimum diameter" everthing should be clear...

but maybe you can explain how do you get a fitting onto the tube without stick something into it... so the diameter has to be at least a bit smaller then the inner diameter of the line. Maybe i'am wrong but i've never seen any method of putting a fitting and a tube together without making the diameter smaller.

That's two words

The tube stretches when you slide it over the fitting - that's how.

Ups, sorry ;-)

you are right... if you have a tube which will stretch... i have a teflon tube and this one won't strech :-) but the info is ok for me... thanks

 

I have -3AN and -10 AN fittings sitting here and the measurements are as follows:

1/8 NPT to -3AN adapter
1/8 NPT side = 1/8" inner diameter, 3/8" outer thread diameter
-3 AN side = 1/8" inner diameter, 5/16" outer thread diameter

1/2" NPT to -10 AN adapter
1/2" NPT side = 1/2" inner diameter, 13/16" or 7/8" outer thread diameter (too close to tell)
-10 AN side = 1/2" inner diameter. 7/8" outer thread diameter

I also have a slip fit -10 AN hose end http://www.summitracing.com p/n AER-FBM1514. The inner diameter is still 1/2" but the outer diameter allows me to fit a 5/8" inner diameter hose over the barbed end of it. I dont have any slip fit -3AN feed lines cause we all know that's a bad idea.

If those aren't the measurements you need then maybe you will have to rephrase your question.

 

Well it has to stretch a little bit - how else does it go over the fitting? Even steel braided lines will stretch at the end when you cram them onto the hose ends.
