A good rule of thumb to use is that no more than 12 inches of rubber hose be used. That was the rule for drag racing. This applied to the entire car, front to back. The solution was to use rubber line made for high pressure applications like fuel injection and cover with braided line, or use the braided steel lines from the factory on most domestic cars. One can easily acquire these lines from the junk yard by seeking out fuel injected V6 cars, and cutting the lines near the firewall where the steel or aluminum lines terminated and became braided for flexibility to the fuel injection rail. A compression tubing fitting from your local auto parts house will mate this back to your original line. The best cars are those with multi-port fuel injection as they had higher fuel pressure requirements than TBI units did. These lines are good for at least 80 psi, and if gotten from an early Volvo or VW fuel injection are good for over 100 psi (GM units are designed for 30-45 psi with 60-80 psi max; VW or Volvo early 240 & 760 models 80 psi max 100 psi).
