In the 1994 electrical diagram (I assume it will be the same for the 92 version) both fuel pumps are fed by the same circuit. This circuit is switched by the fuel relay. However, the in-tank pump is fed via fuse 11, whereas the other fuel pump gets its 12V directly from the relay. In other words: pulling fuse 11 will disable the intank pump, but not the underfloor one.
