Moroso fuel cool can

Yep,, vapor lock.60's and 70's. We ran the homemade cool cans as stated above. Some guys would wrap the fuel line with cloth and soak it with water before making a pass. Back then everybody had the hand pump bug sprayers and would cool down the radiator between rounds.Ice on the intake manifold too. Back then they weren't as anal about track prep(none at all).but they did have the mop for the excess.
