TPI Fuel Rail Fitting Size???
I'm in the process of swapping in a TPI 350, and got the Accel TPI -> -6an fitting to adapt the fuel lines, but only one of them fits the fuel rail. Are the TPI fuel rail fittings the same size? both of the adapters are the same, but one doesn't come even close to fitting. Any other ideas on how to adapt the fuel rail to a total custom fuel system? Finding the oem lines is not an option. New ones are too expensive, and there isn't a used one here (Italy). Thanks in advance. Nick

The fuel lines for TPI are not AN style. The line itself has a flare on it that fits up in the fitting on the manifold, the line also has the nut on it that screws up into the manifold side and they are NPT nuts, like brake lines.
Nice of GM to use a system like this that can't be played with, huh?

I just finished swapping a TPI intake into my dads 77 vette. I used power steering fittings. I am not sure what size. If you check back I will try and post that info soon. I think the threads are M18 but I am not sure of the dia.
