I couldn't believe that the fuel filter was the culprit...but I reversed the flow of fuel by blowing into the removed filter and a whole bunch of crud came out of the filter...normal driving I didn't notice anything, but when I boosted and needed a greater fuel quantity, then the restrictive fuel filter would not allow fuel to flow.
as far as the *mod* goes....I do have a modified APC box which gives more boost. But I also have a 3.0 bar FPR...
The fuel cutoff is under the dash on the driver's side mounted above the pressure sensor. Depending upon your year 900 you may or may not have one. Cars with LH2.2 havve one...later years with LH 2.4 & LH2.4.2 do not have an external cutoff..it is integral with the ECU and cannot be bypassed
If you have an earlier car with LH 2.2 you could also connect the terminals attached to the cutoff switch. It was easier for me to splice the vacuum lines together bypassing the switch. If you just pull of hte vacuum line running to it and plug it, you also will not have your boost gauge working in the instrument console. That vacuum line is connected to the cutoff as well. Connecting the line going to the cutoff (from engine) and the line coming out of it (going to boost gauge) will allow the boost gauge to work.
