hopfully im gonna be installing a fmu sometime this week but first i have to buy the right fittings and such and also locate the fuel return line.

so very simply where is it and where is it most visible and easily gained access too, and how big is its inside diamater so i can buy all the correct fittings for it.

also has anyone successfully relocated their windshelid washer bottle. because thats mostlikely where im gonna have to mount the thing. since thers conviently no space left in my engine bay.

there are the three lines that are all next to each other coming off of the intake manifold. The fuel line in is the line coming out of the fuel filter. This leaves to other lines. One is really small. This IS NOT the return line. The other normal sized line is.

but for shits and giggles, go to the fuel pressure regulator over #3 piston and follow the line back to where the hard lines stop. This will ensure the return line is the correct one tapped.

Good luck.

The inner diameter of the stock hose is 7.5mm. 5/16" is pretty close.
