The standard fuel rail does have a return to the tank, but feed line and return line are both too small for what we are needing to achieve so we needed to replace the factory fuel rail to increase the size of lines and a better fuel pressure reg. Climax Airbrushing did the Falcon on the rocker cover, if you have seen any of their other work at any of the car shows they are amazing from little things to whole cars. They painted the rocker cover as a gift for me so I dont know how much it would cost. As far as the mechanical work on the car, it has all bar trans and suspension been done by G-Tech Performance in Campbellfield VIC, it is my car and not a business car but my brother does own G-Tech so therefore I get a resonable deal on work done price wise. If you ever wish to see the car in the flesh or want to go for a ride to see how it is still very driveable it is at G-Tech most of the time. Thankyou for the compliments on the cars looks!!
