OK the Time has Come

Im trying to figure out how to make a fuel tight access door to get to my fuel filler cap for my fuel cell.

I know that the tank need to be spreate from drivers compartment so how do you access the filler cap?

any ideas?

The Top is Alum and will be beadrolled for strangth then bolted down with 1/4" hex head bolts spaced 2inchs apart all the way around with an RTV Gasket to make sure it is sealed.

The rules do not require the fuel door to be fuel tight. All they are trying to do is to keep fuel from sloshing into the driver’s compartment. Most people just have a hinged sheet metal door in the panel that covers the cell. I used an aluminum door that pivots open on one bolt and is held in place with another bolt with a nutsert.

I just bought some aluminum angle from Home depot to make an edge that hangs down.

Here's ours. Like was said above, it's not fuel/air tight, just a fire break with the suppression nozzle inside.

Made from sheet aluminum.

The rest of our cell is below the floor.

I sent you a reply to the PM. Similar to the others, a hinged access door and I use a Dzus wing head fastener to keep it closed.

Wow you guys, Speedy Reply!!

Thanks so much that make it 10X easyer i always thought it had to be fuel/water Proof,



I guess ill just make a door with 1/4" turn fastener i have laying around and maybe ill put some foam stick on weather stripping aroung the door to make it some what tight fit.

Im using this cheap cell for now but next year im going to upgrade to a ATL Cell ,

Thanks for the pictures

My first race is in 2 week and the car wont be in paint oopes
but every thing else will be done (i hope).

Thanks again you guys.

Why didn't you paint your fuel cell "basket" after you welded it? The rust is not good for welded joints. Granted this will not be a problem for a couple years, but $3 at home depot could have made the project look a lot nicer and prevent a failure a few years down the road from the corroded joints.

SCCAITS 04-07-08 11:15 AM

It would help if I read the threads before replying to PM! The actual rule verbiage is below, you'll see nothing about "air tight", "water tight", etc.

GCR 339: "In any automobile where allowed removal of rear seats, upholstery, etc., creates an opening between the driver/passenger compartment and an exposed gas tank, fuel cell, or part thereof, a metal bulkhead which completely fills such opening shall be installed (See GCR 9.3.26.1.)"

9.3.26.1 - Internal body panels may be modified to accommodate the installation of fuel cells as long as modifications serve no other purpose. In the event If installation includes encroachment into the driver’s compartment, a metal bulkhead must prevent exposure of the driver to the fuel cell. The fuel cell must not be installed any closer to the ground than 6 inches, unless enclosed within the bodywork or OEM floor pan.
a. There must be a metal bulkhead between the driver/passenger compartment and the compartment containing the fuel cell. This includes fuel cells that are flush mounted with driver/ passenger compartment panels or otherwise exposed to the driver/passenger compartment.
b. Fuel cells must be located within 12 inches of the standard tank. The 12- inch measurement is taken from the perimeter of the stock and alternative fuel cell. Fuel filler location is unrestricted with installation of a safety fuel cell.

Yeah thats what i thought

I must have been thinking to much in to it
I figured that in case of a roll over that it would have to be air/leak proof

Thanks for your help

I did grind down the joints when did the welding but the new weld that you are seeing and wider then that had to be

What i did was i let the whole thing rust so i could use PUR15 It sticks better to rust that clean metal

We use this stuff all the time on all of our resto/ custom projects Its think and last forever! and will NOT come off your hands, Only with time will it come off
