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. |

I agree that the stock design has problems. In my case, one of the short hoses from the aluminum rail to the injector was very slightly bent, causing a restriction. The amount of restriction changed with the slightest movement, and as a result, I had a very annoying bucking while trying to accelerate through the mid RPM range. Easy to fix w/ fresh hose, but a real PITA to track down. Sounds like you're still going w/ those short rubber hoses. So definitely make sure they are straight and under no load when youmount the rail to the bracket. Oh, and be sure the rail is CNC machined from aircraft-grade billet aluminum and anodized in a pukey color. |
