I'd recommend looking at a set up with some dry break quick disconnects for filling the cell. Use the RA-approved braided fuel line plumbed in to the tank for the fill.

A quick search revealed a set of 1/2" size couplers that flow 17gpm for $48: http://www.discounthydraulichose.com/ISO_16028_Couplers_br_complete_sets_p/ht-set.htm

$20 for a barrel pump from harbor freight: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=45743
Weld a fitting on the nozzle of the pump for the other end of your fill line to attach to and feel like a real fancy pants race car man filling your fuel cell from a drum. Or just hose clamp the fill hose over the nozzle of the pump so that in an emergency you can stick a funnel in the fill hose and pour gas in that.

Then you've got no issues with additional boxes and lids and caps and funnels and trying to pour gas from a can into your trunk.

This picture below shows how to do what I said above and spend ~$2000 doing it. Stupid staubli connectors are dumb expensive. But you can see the lower big hose is for the fill. The upper big hose is the vent which tees off through a roll over valve to a smaller regular vent line which exits out the bottom of the car.



To fill it all the way up you crank your pump until gas comes out of the big vent line (into the small pail you brought with to the fuel depot just for that purpose.) Or you have the driver watch the gas gauge as you crank and he tells you when its full enough. You could also get away without the big vent line dry break if you didnt mind it taking a little longer to fill up.

As they said in Deliverance....'boy, ya shore have a purty...trunk".... nicely done !

I like that alot. That's partly what I was thinking of with AN-16 lines that I have laying around. What size fittings are on that Subaru?
You can also accurately measure how much fuel comes with each 360 degree rotation so you'll have a pretty good idea of how much volume you are putting in with each rotation.

I think those were -16 if my memory is right.

You'd have to have rollover fills on both vent tubes too. Just saying...

Grant Hughes

You mean rollover valves on both big hoses?
Why? The dry break fittings wont leak if they're upside down.

I like that setup. But to be legal for a 2 box car wouldn't all of this including the dry break be behind a bulkhead?

As an option could the cell be inside a box with just the big hoses coming through a bulkhead fitting and then the dry break fitting being in a second box near the back of the car? While the large lines ran exposed between them. This would be no different than running your high pressure and return fuel lines inside the car, correct?

And that box would need to be in another box.

But no, I think that the dry break could by the rules be exposed.

See? That doesn't look so hard now, does it?

Glad to see the Capri finally got finished and driven in anger.

Same thing I'm doing with my install. I'm even going to reuse the stock fuel pump access panel as the cover - it already has a rubber seal on it

WTF. How did I do that. Must have been because I had just seen the Fiesta thing before. I know you're Carl.

Okay, so the picture Tom took was allowed because it is accepted as legal and is a kit sold by ATL most likely.
Was flipping through the December 07 or 08 issue of Racecar Engineering and in the new products page was something from ATL that looked just like this. A remote fill with a piece of dryer hose that was hose clamped at both ends.
I'll post a pic from that issue later today.
But here you can see the 'aluminum fire guard' pictured.

Can't find the 'kit' that was being referred to in Racecar Engineering, but definitely had all the components.
