little help please???

Is the schraeder valve on the pressure side of the fuel rails?

Does the FMU, (I'm assuming that's what the little round, anodized disc shaped thing with the gas line in and out and the vacuum connection on it is...) go on the pressure or return side of the fuel lines?

further, does anyone know which of the two fuel connections is in or out on the fmu thing? there's one which goes straight into the bottom, and one that comes out of the "side" of the fitting at the bottom...

Moral of this p.i.t.a. is, when you take apart your donor, don't wait 2 years to then assemble your cobra....

The schradder is on the pressure side. The fmu goes on the return side. Fuel off the rail return goes to the side of the fmu and out the bottom

It has been a few years since i have used an fmu but. I know for sure it goes on the return line. I believe the in is on the side and out the bottom.

Better yet, get bigger injectors, ditch the FMU and run a custom burned chip.

The car will run better, be safer, and make more power.
