Whats the purpose of a fuel cooler?

I've never heard of anyone having these on a turbo system so Im curious what they're for. :)

To cool the fuel and thus the air before it goes into the cylinders, I saw one that ran the fuel through ice water but that one isn't going to cool the gas any more than it already is-total ripoff.

anyone who has EVER pulled off a fuel rail will know that fuel is cold as it enters the engine



it sits on the other side of the vehicle away from the elements and any heat source

The purpose of a fuel cooler is to remove cash from your wallet.

This is prolly more directed toward cars that have problems with vapor lock.



Although the fix for vapor lock is to simply move line away from the block.

High HP race vehicles with MONSTER fuel pumps and small fuel tanks, cycle the fuel around the system twice as fast as a street vehicle with walbro would. Therefore, succumbing to greater pressure in the lines, and more time through the engine bay and pump = Cooler needed.
