if it was vapor lock i would think it would happen sooner but i will tell you that the mallory 140 pump with return style reg (4309) was one of the best things i have done to my car. i had bad vapor lock issues with original six pack setup i had and that took care of it

also, i dont think fuel line inside the car is a good idea
