AN fitting vs fuel line size? Options

[stugray]

I want to buy a fuel cell.

It says that it has:

10AN Male inlet
8AN Male rollover
8AN Male return

http://www.jegs.com/i/JEGS/555/15551/10002/-1

When I try to lookup AN fittings vs. fuel line size I find:

-3AN - 3/8" ID
-4AN - 7/16" ID
-6AN - 9/16" ID
-8AN - 3/4" ID
-10AN - 7/8" ID

So .... are they saying I need fuel lines that are 3/4" ID?????

That is ridiculous. I have a coil of braided stainless hose that is ~5/16 ID.
It seems like the logical size for fuel line, so that seems like -3AN to me.

Why would the fuel lines be so large from the fuel cell?

Seems like a lot of expensive adapters for two tiny lines through my tunnel.

Any help would be good.
I must be missing something ......


And I suppose the "10AN Inlet" is for the feed to the fuel pump/pressure-regulator and the "8AN return" is the dump line back from the pressure reg.?

Ok,

Thanks for all the help.

Brant came over and gave me some tips after seeing my rust free, running, perfectly straight, race 914 that I bought for $1k (IMG:style_emoticons/default/biggrin.gif)

He said to just use 3/8" brake line that you can get at the local auto parts store and replace the tunnel lines with that once the motor is out.
I assume that 5 feet will make it all the way?

Then I guess I will need to buy the 8 & 10 AN fittings that come from the fuel cell and adapt that to the 3/8" brake lines.

I assume that 2 hose clams will work for that.

So next question: I guess I will have to adapt the 10-AN and the 8-AN fittings down to the correct AN fitting size of braided flex hose to slip over the flared 3/8" brake line.

If the ID is 3/8", then the OD is probably ~1/2" so a 8-AN tube would fit nicely over the brake line.
I would still need to adapt the 10-AN down, but thats only one fitting.
I think I wil get 90 swivel fittings for the fuel cell.
Sad that all the fittings I will need cost almost as much as the cell (IMG:style_emoticons/default/blink.gif)
I think I am ready to call Jegs (IMG:style_emoticons/default/beerchug.gif)

Anybody see a problem with this plan?
