Lingenfelter L710660504 Lingenfelter Pontiac GTO Fuel Pump 2003-2006 v4.41 - Manual (Page 12)

39. Module Modifications.
For the fuel pump to sit properly in the module, some modifications need to be made. The
three ribs inside the top part of the module, indicated by the screwdriver (shown in figure 1) must be
cut back until they are above the small windows indicated by the pen in figure 2. Make sure that the
ribs inside the fuel pump socket do not interfere with the new pump when it is installed. Removal
of the ribs may be done with a die-grinder type tool and coarse cutter/abrasive attachment or a small
knife.
If you don’t fee comfortable performing this modification, you can purchase an already modified fuel
filter from LPE.
