Not knowing exactly what kind of contamination your talking about, but it has to be very microscopic to get past the fuel filter. But rust particales can build in the fuel distributor and stop it up along with the injectors. If your going to replace the pump and accumulator then a FD may be in order also alsos with either replacing the injectors or cleaning them.

Is there any proceedure i can follow to check how far the fuel contamination has gotten(like if it got past the accumulator/distributor up to the injectors? I'm considering just replacing the fuel pump/accumulator/filter just to be safe, is that absolutely nessesary or could I check if any of those are still good? Also how could i check the distributor for rust (hence injector contamination)?
