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.?

Thanks for that!

It makes sense now (never trust a quick web search).

So should I run 8-AN (1/2" ID steel braided hose) through my tunnel, or convert the AN fitting to stainless flare before going through?

I plan on moving the fuel pump to the front since I removed the tank, but I still need two lines from the tank to the engine bay for the pressure regulator, right?


"Curious, why do you want a fuel cell?"

-6 will flow all the fuel you will ever need, and the smaller hose and fittings will be lighter and cheaper as well. There are reducing adapters available.

For all questions like this, check out the information on the Earl's website, remembering that the are now a Holley company.
