This may sound too obvious, but instead of using fuel rails, couldn't you use double banjo nuts to daisy-chain flexible hoses instead? Sure, that wouldn't look as elegant, but it would be very functional. I would be worried that a custom-made fuel rail would need very critical tolerances or else it would hold the injectors in crooked. Maybe parts from the Eagle Premier is the answer. But then jwit6 did it with brass water pipes! Walt Tampa, FL
