Ferrari 246 F1 fuel tanks

Is it one of these?

(that one has the engine angled the wrong way, so not very trustworthy)

As mentioned. Apologies for the delay, modem o/c

Disk brakes, coil spring independent rear suspension, drive shaft running from left to right. It looks like a 1960 car.

Also the low exhausts. I agree, that is not a 1958 Dino 246.

.....there is an unattributed cutaway in his Dino 246 1958 chapter which seems to show tanks on left and right sides, plus the tail tanks. Nothing is specifically mentioned about them by year, but for 1960 he says
" .... for 1960 independent rear suspension was officially adopted and an improvement was sought for the weight distribution of the 246 by going back to side tanks, leaving the one in the tail for fuel reserve and oil. For the same reason the engine was moved back 25cms.; moreover, it was offset in the opposite direction, angled from left to right passing to the right of the driving seat. The gearbox lever was moved to the left..."
Does that help at all?

I made no claim that it was anything other than what was in the book. The interesting aspect is that Casucci suggested that they went back to side tanks. To what vehicle as a base spec. and in what period he does not say, but I thought in view of the close scrutiny of this topic it might indicate that there might have been a similar installation on a 246 at some time prior to 1960. I have checked the same volumes as mentioned in other posts. Casucci's chapter titling simply goes by the model and year of introduction, hence his 156 chapter is for 1961 but covers up to 1963

Depending on the context, there are several things he might have been referring to. The original Dino, in 1957, had a single cockpit tank but carried most of its fuel in the tail but is it possible that he is referring to the Squalos of 1953-55 or the original Lancias, both of which carried most of their fuel between the wheels?

I have heard it said that the tyres of the mid-50s were unable to cope with the sudden breakaway inherent in this configuration but by 1960 they had improved sufficiently to make it practical. The Cooper and the Lotus 18, of course, had a similar weight distribution.

That is how I read it, but just thought that there might have been a Dino variation of it

I don't know if this helps but this photo was taken during the winter of 1958/59 In the foreground is one of the new 1959 cars and on the left one of the 1958 cars in its final form.

Gentlemen, I can now announce that I have fired up my old steam-powered time-machine and gone back to the end of 1958 and have stolen the Hawthorn car (hence JMH couldn't get it from OMF), delivered it to those TV blokes who chop things in half to show how they work, then taken it to the people who over-restore Ferraris for salon photos:

Still no evidence of a RHS tank though...

I assume by the number and the screen that Macca's picture shows Hawthorn's Rheims car -but has it got a four spoke steering wheel?

DSJ's British Grand Prix report says that Collins and von Trips had (left side) cockpit tanks but Hawthorn didn't. He doesn't mention them in the Rheims report but it's possible that all the cars had extra capacity for that fast race and that it was removed from the team leader's car for the slower race at Silverstone. Does anybody have any evidence?

No, it's got the wrong wheel, and the body wasn't two inches thick either......and other pictures I've seen of this 1:20 model by Revival show the tail to be a shape that looks wrong.

I have both the 1-20 Revival and 1-14 MG kit on my to-build list and so have done some research on the side fuel tank(s) of the 1958 Dino 246. The Revival kit has both LH and RH tanks but significantly positions these tanks outside the chassis frame and inside the side body panels.

I've followed the cutaway drawing thread of this forum for a couple of years and know you will find several cutaways of the Dino 246 with various arrangements of side fuel tanks. A year or so ago I found a cutaway drawing by Robert Roux of the Dino 246 chassis frame. I think the source may the long out-of-print book by Pomeroy and (Sitrling) Moss or an early edition of Tanner's Ferrari book. However, the drawing shows metal straps to secure the front and rear of a fuel tank inside the left-hand chassis frame with no corresponding item on the right-hand side. Not proof but a pointer!

I've clicked on <Insert Image> but have failed to upload the cutaway. Help would be welcome.

My apology for being a few years late, but I've only just picked up on this forum. I'm a scratch builder working in 1/8th scale, and one of the cars I have been researching for a long time is the 1958 Dino 246 in both large and small tube chassis variants. I have just sorted through the mountain of photographs I have built up, and with regard to DCN's comment of 5th August 2012, the small tube Collins Dino had a thin slipper tank on the left hand side of the cockpit. There is no tank fitted on the right hand, gear change side, of the cockpit, and certainly no fittings such as straps or mountings on the chassis tubes. I have scanned the photographs I have of this car whilst it was being prepared for the race, and from all angles nothing to be seen. All the photographs I have of the large tube chassis cars would suggest the same, with no tank on the right hand side being shown in any of the photographs I have. Were a slipper tank of the type fitted to the left hand side be inserted on the right hand side it would sit in the space needed by the gearchange, and linkage. I have created drawings in 3D solid for model making and there is no room for such a tank on the right hand side. I hope this late addition helps a little.
