FITECH FUEL COMMAND CENTER MODIFICATION

hemidart,

I just completed mine. Here lately its been in the 90's and my old setup would stall and start back up in 10 minutes. I already had converted the FCC vent to a full on return to the filler neck with a barb. Reusing the factory cannister vent line front to back. There is a rubber splice in the vent tube about midway I replaced with fuel injection grade hose , maybe 2 inches max. The vent seems to be ok at 1/4" diameter.

The hardest part of the mod is getting the lid off and on. I used WD-40 finally on the oring and my biggest channel locks to get into the notches around the circumference. I used a small punch on the back side of the pin that holds the brass filter stone that comes out to remove it. Then some vice grips to twist it out.

As far as operation the most notable thing is the inlet fuel pressure gage is either on 0 or between there and 3. That makes sense as the needle and seat are disabled.

Seems to run fine after some driving, deliberate long waits at idle with hood down and 185 deg engine temps. Engine start and stops too. Myself I would like a 5/16 return line but if this works I'll leave it be.

FYI,
Marion
