According to my info, for '65-6 Shelby's, Shelby American cut the top
off of two '65-8 gas tanks and welded them together, resulting in a 32
gal fuel tank. This may only be on the "R" models.

My question is, what did they use for a float? Did they rob a sender
from another car line, or just stick a stock Mustang sender in?

I have about four 16 gal tanks, and was considering doing this. My car
will be a weekend cruiser, so I could care less about losing trunk
space, but I do want an accurate fuel guage. Considering the FE over the
front wheels, I need as much weight in the back of the car as I can
muster. I figured a trunk mounted battery and a 32 gal fuel tank might
help even out the weight distribution.

I'm always looking for '67-8 Shelby and Mustang fastback specific
parts.
Also 428 CJ specific parts, let me know what you have.

This is a really cool setup! I have thought about doing this too. From
what I understand it was only for R models. There was also internal
baffling to reduce weight shifting (I would do this too). The filler
system was a conical shaped splash shield with a Cobra style gas cap (I
sure wish I knew where I could get a splash shield like that). The gas
fume exhaust vent ran between the tank and the passenger compartment,
then back around and through the trunk lid well (looks really trick). I
never saw any mention of the tanks being welded together - is that true?

HTH,

Paul

Have you thought about extending the arm on a standard gauge? It seems
to me that if you try to bend it up to reach the top of the tank, you
won't have enough throw left to reach the bottom (and visa-versa).
However, if you were to extend the reach of the float arm, you would
be able to spread the range enough to compensate...

some cheap thots... ;-)

I'm not sure what they actually did but if you left the standard gauge
in the tank it would read full until it got to the original level then
the gauge would work like you had a 16 gallon tank.

Well, it should have been a non-issue because they *should* have
removed it entirely, blocking it off appropriately. (No need to carry
the extra lbs around the race track, right?) But a street vehicle on
the other hand, could make use of fully functional fuel sending unit...

Cheers!

I'm quoting Tom Corcoran, in a book I have called Shelby Mustang. There is
a pic of the fuel filler that is detailed enough to try and fabricate
something. It looks like you could make the cone out of aluminum, and use a
flip open gas cap.
If your interested in the pic, let me know. I can scan and post it to my
site.

The driver has to know how much fuel he has, be it on the street, or on
the track/

R models and some of the Trans AM coupes

No float, not sender, no fuel guage

Thanks for the offer Michael! I have that book too. I was looking at
it real closely the other day and it appears that the filler bowel might
be two pieces (there's a very faint line that can be seen going down one
side and what appears to be another line directly across on the other
side. I wonder how they actually made this part?

Since Shelby didn't use a sending unit in their vehicle I think I'll
probably use the stock unit and wait 'til it passes the half way mark
before it starts reading... Does anyone know if the tanks were welded
together or just bolted with a gasket?

Thanks,

Paul

While its possible the filler bowls were a one-piece
stamping, I'd vote for "spun"...the originals I have
seen exhibit typical, concentric markings. This also
holds true for the (very similar) carb plenum chamber
used on R-models and other race-only Mustangs.
