Fuel Cell Capacity for Vintage FA

[Jerry Poole]

What would be the average fuel consumption of say a BDA/BDD for the average vintage practice/qualifying session or race, (non enduro), with say 45/48 Webers or fuel Injection? Trying to determine the capacity of a fuel cell for a FA restoration project that does not currenly have a cell. Would a 5-6 gallon cell suffice for the normal vintage situation? Appreciate any insight and information and thanks. Jerry

Since most FA Vintage sessions don't exceed 30 minutes, a 5 gallon tank with foam is sufficient. My 78B came with a 7 gallon tank that fill it with 5 gallons for a 30 minute race, giving me a cushion of 1/2 to a full gallon. My Brabham BT-35 with an injected Cosworth FVA (1600) had a single 5 gallon tank which also was enough for each session. If weight is a concern, fill it accordingly for shorter sessions.
