i think i have the "craptech" fmu now, it came with the hahn kit.. im installing my p/p intake mani and #30's and SFMU. i looked at it, and the "fuel in" is diverted to the craptech unit, and then its output goes to the rail. so to install my SFMU do i need to have the "fuel in" going to the fuel rail ?

Are you sure it's fuel in? It sounds more like what you are looking at is the return line from the craptech to the tank and the line that goes from the rail to the craptech. Which side of the fuel rail is the "output to fuel rail" Late fuel system, if it's on the left (passenger) side of the rail then it's the return not the supply line, and your sfmu setup is going to be the same as the cartech except you're going to be using better parts. The supply from the tank is on the driver side of the rail

well every 1 is so quick to think its a simple instal and i just dont et it.. its not the case, there is somthign installed already, idk if its craptech or what but i traced the fuel lines, it goes from the in line, the line that hooks up to the rail, they cut that , ran it to the right side of w/e unit that is, then a line on the left side went out to the fuel rail. so i was asking if i needed to make thos lines back to stock....i already did so i guess we wil see how it works with the sfmu. and yes im SURE its not the return line.. the nit is simply in between the oem line and the fuel rail. i put it back to stock, then added my sfmu, side prt to the fuel rail test port(schrader valve removed) and a return fuel line to my 255 pump. 2.72 ring.disk with #30 injectors. and i followed thee advice and went -6an for my return and -4an on everything else. so to awncer my own ?, yes return it to stock..

Sounds like whoever had the car before you did it wrong. The regulator should always be AFTER the fuel rail. Fuel goes into the fuel rail and the regulator regulates by increasing and decreasing the FP in the rail on the "out" end of the rail. Take a pic and post it up, it'll be easier help you.

Need help with your CrapTech FPR uninstall? Here's a vfaq:
1) Rip the fucker out.
2) Toss it across the fucking yard. Using a shotput stance and wind-up helps your range.
3) Take a dump on it.
4) Launch it out of a potato cannon. If you have no potato cannon, just spray some starter fluid in any crappy titanium ricer muffler you have lying around, and BOOM.
