Clothes Pin On The Fuel Line?

Nice photo of your set up and your fuel line routing is fine. The theory is of the fan air movement cooling the fuel line,tho doesn't do much on a hot non running engine. I run a electric booster pump such as the Holley Mighty Mite,also sold under many names, (Jegs # 510-12-426 $49.77) installed close to the tank as possible, switched to run during starting then shut off allowing the mechanical pump to do it's job.Worked very well on my 79 Chrysler 300. I also run one on my 65 Belvedere and many of my Slant Six cars over the years.
It sure is small and quiet but cured my problems. The number above is for a 1.5 to 4 psi pump. For fun I removed my mechanical pump to see if it would keep up to the 360 and Thermo Quad. Never skipped a beat even in the heat of the Nevada desert. I did re-install the mechanical pump after the experiment. Just something to think about.
