Hi. Can someone tell me what size fuel cell they run in a vintage FB. Mine is a wedge shape under/behind the seat. It runs a Lotus twin cam. Is 5 gallons big enough for the FB events run? Thanks in advance.

Experienced runners out here consider that the realistic min. size for a vintage FF.
Graham - I presume you're asking for the Mk.6 LeGrand that you're restoring. Back in the day (1967-69) we ran 30-minute Nationals with the behind-seat aluminum tank and never had a problem - are you sure it's not a bit larger than 5 gallons?
But if you want more capacity, don't do what we did for the "pro" series - built a long thin aluminum tank to fit into the left-side curve of the body side and hung it with two long hose clamps from the frame tubes. I was really glad I had taken that tank out before the LA Times GP supporting races in October '69 where I crashed into the Turn One pit wall...
Hope all is going well with the LeGrand -

Yes Gerhard it is for the LeGrand. As I have to use a fuel cell now I am just trying to see what others are running. I have a 4 gallon in my FF and have never run out and have done a 40 minute race but we did have about 5 yellow laps. I know this will use a bunch more gas than the FF motor though. It is coming along and looking better all the time.

If it was me, I'd err on the side of larger. You can always put less fuel in a bigger tank but can't put more fuel in a smaller tank.

Graham - that chrome plating on the suspension really looks sharp. As I told you on the phone, "Red" always liked the way chrome looked, and as long as we got the platers to bake out afterwards, we never had a hydrogen embrittlement problem.
I also see that you have an engine cover. I have to say that we were never really happy with the "styling" of that stubby cover in its several versions, but it does add a more finished look to the car than just total mechanical emptiness behind the roll bar.
Keep up the nice work!

A few years back I was in a 30 minute race. At the end, there were FB cars strewn around the track - we all ran out of gas at the 28 minute mark. A FF won the race. Since then, we redesigned my fuel cell to hold about 1/2 gallon more. I can send you the drawings if you want (send me a PM). I've only run 20 minute races since then. BTW - SVRA promised no more 30 minute FB races, but I'm not sure if they will stick to that. You are doing the right thing by planning for a 30 minute race.
BTW, the car looks fantastic. Great job on the restoration.

Thanks Darrell. I have send you a PM.

I would recommend at least 6 gallons. And I’d recommend a hydramat as well to help get it all out. If you run at a place like Elkhart, the Glen, Daytona, COTA, etc where you will spend more time at WOT, a B car will need every bit of that 6+ gallons.

Might be a good idea to fab a sheet metal bracket to go under the sway bar mount and make that A-arm attachment double shear.
