yah i looked at that and i got 90% , but my fuel rail only has one port, the oem port and the schrader valve. so do i need to make a hole in the other side or get a diff fuel rail? or does it go into the shrader valve?

the test port on the fuel rail is where the line to the sfmu connects you take the cap off of it, then remove the schrader valve inside

For future reference it's SFMU not smfu
It just adjusts fuel pressure based on manifold pressure, fuel is not supplied from the sfmu to the fuel rail. Pressure is increased across the rail when there is positive pressure in the manifold

Yea I ran into this problem too
I think its funny he corrects this guy for saying sfmu instead of SFMU but in his sig it is in lower case
