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, so I have done the following:

Verified that I can get 2X 3/8" flared steel lines through my tunnel, however I cannot fit the flare nuts through so I will need to cut them off.

Moved the fuel pump to the front gas tank compartment (no gas tank).

Installed the Fuel cell in the spare tire area with 6AN fittings and 30R9 3/8 fuel line through the firewall with grommets.

So I have a few more questions:

1 - Can 5/16" (30R9) fuel line clamp to the stock fuel pump and be safe?

2 - What is a good aftermarket fuel pump that can run the FI AND carbs ( when I convert in the future )?

3 - For the engine side of the 3/8" steel fuel lines, what do I need to convert the 3/8" flare fitting to more 5/16" fuel lines to route up to the fuel rails?
I will be capable of leaving the flare nut on on that end so I assume that there is some adapter to go from 3/8" flare to 5/16"...

4 - I assume that I can have one of those clearview fuel filters between the fuel cell and the pump since that side is under vaccum and not high pressure, right?

5 - Should I put another fuel filter AFTER the fuel pump in the engine bay? If so, I assume I need a high pressure filter...
