there's easier way to cool the fuel today
some of them hi-dollar cars are cooling the air-charge
usually, turbo'd or centrifugal superchargers air inlet temps are high
more than just fuel too
many people run (or ran) fuel thru a sort of trans cooler type deal
like a Derale trans cooler, with a fan assist
helps too
mounted in the cool air nowhere near the radiator, exhaust or engine heat
or a heat sink
In my Top-Sportsman car or Outlaw Pro-stock cars
we used thermal/insulation wrap,
or thermal shielding sleeves to protection on all fuel lines
to keep as much heat as we could out of the carbs
much like stuff DEI makes today
I have used a small oil cooler from the 80's
with 2) -6AN fitting like 4 loops 1/2" copper/brass finned tubing
(like a mini trans cooler like 9" x 4")
mounted off to the side in front of the core support
so fresh air can pass over it
I use/used on my 68 RR steetbeast
I did it to keep the fuel & the pump cooler
(I also use a bypass style fuel reg. to help keep fuel & pump cooler)
& so I wouldn't have any vapor lock issues in the summer,
if it makes more power that's just a bonus,
it's light doesn't take much room, I figured wth, why not
every lil' bit helps,
when everyone is about the same level of power
