Like most people I'm not too thrilled with the design of the fuel rail system. I'm planning on buying 2 6" pieces of aluminum fuel rail and tapping it for 5/16" barbed fittings (3/8" NPT). I'm assuming that 3/8 NPT -> barb 5/16 exist. I found em.. on ebay

Does anyone know what the exact OD of the fuel injectors are? I'd like to use 5/16" high pressure fuel line on everything.

I'm pretty sure I'll have to fab a bracket to support the extra weight of the fuel rail. I'm surprised the stock fuel rail is floating.

I'll also tap a 1/8" NPT for the fuel pressure gauge.

I've seen a fuel rail kit on the market, but it costs $170 or so. I can build this for ~$30.
