4 x 6 plate - A standard size, 12-bolt oval plate which covers a 4” by 6” hole; the plate measures closer to 5” x 7”.

6 x 10 - A standard size 24-bolt oval plate that covers a 6” by 10” hole; the plate measures closer to 7.5” x 11.75”.

Alcohol Fuels (Methanol, Ethanol) - This fuel can be harmful to safety foam and certain bladder materials; aluminum hardware and specific materials should be treated.

AN Fittings - A mil spec standard for fitting sizes. AN fittings and NPT fittings are not interchangeable. A dash in AN terminology is the hose size the fitting is designed to work with. Each dash represents 1/16 of an inch; e.g., a -8 fitting equals 8/16 or a 1/2" hose, a -12 equals 12/16 or a 3/4" hose.

Baffle (bladder material) - Deflects fuel flow in a cell to an area you want it to go for better performance.

Foam Baffling (Safety Foam) - Minimizes fuel cell slosh while providing explosion resistance.

B.C. (Bolt Circle) - The diameter of an imaginary circle drawn through the center of each lug hole; also referred to as the bolt pattern.

Bung - A weld-in threaded fitting that will accept AN or pipe fittings; must specify AN or NPT.

Can - The enclosure (container) that provides containment and protection for a bladder.

Check Ball/Check Valve - A device that allows flow in one direction only.

Collector/Surge Tank/Sump - An area within a cell that traps/contains fuel to ensure steady supply & maximum usage.

Dry Break Valves - Valves that form a relatively leak-proof connection for rapid refueling.

External Flange - Can flange that extends outward and provides a flat surface for bolting the can lid to the can body and is used to mount can in car.

Fill Plate - A steel or aluminum plate that typically has a fill neck, fuel pickup fitting, vent fitting and provisions for a sending unit and wire harness. Fill plates come standard with all of our complete catalog fuel cells.

Valve Flapper - A check valve used in standard fill applications.

Height - The measurement from top to bottom of the bladder or container listed.

Hydrocarbon Fuels (Gasoline, Diesel, AVGAS) - A fuel that requires specific materials to be used in the construction of a fuel cell. This fuel will damage alcohol-specific bladders.

Internal Flange - 1.25" can flange that extends inward to provide a flat surface to bolt on a can access cover (may be on any side but typically on top).

Length - The measurement from right to left as the cell sits in the car (typically cells are mounted with the longest dimension left to right; your application may differ).

Nipple - A fabric reinforced flexible outlet or inlet into which a tube can be clamped.

Nut Ring - A metal ring on the inside of bladder openings that has threads to accept bolts securing a plate.

 

Orientation - Orientation is as the driver sits: to driver's left, right, front, back.

Outlet - A fitting or nipple on the fuel cell through which fuel is drawn out of the fuel cell and delivered to the engine; e.g., a fuel pickup fitting.

Pickup - The hose and/or fitting through which fuel will be delivered to the engine.

Raw - Untreated plates and fittings, no finish applied (do not use with alcohol).

Remote Fill - A cell that is filled other than with a cap mounted directly on the cell.

Return - A fitting or hose through which excess fuel is sent back to a cell.

Safety (crashworthy) Fuel Cell - A safety fuel cell is a fuel containment system that typically includes four main components: a steel or aluminum container (the can), a fuel bladder (this provides the crash protection), safety baffling foam for fuel slosh mitigation and explosion protection, and a fill plate.

Sender (fuel level sender) - Typically an electronic item that sends a signal to your fuel level gauge. Standard Fill - A cell that is filled through a cap mounted directly on the cell.

Vent Valve - A valve that allows air to enter or exit a fuel cell. All vent valves employ some type of rollover protection (a check valve) that prevents fuel loss in the event of a vehicle rollover.

Width - The measurement from front to back of the cell in the car.
