No, as Lynwood described there is a lift pump that feeds the fuel from your tank up to the fuel injector pump. In order for the injector pump to operate at such high pressures it is built with extreamly tight tolerances. The injector pump and the injectors themselves are operated by high pressure oil. Contamination from either bad fuel or dirty oil will cause the pump and injectors to fail. There is a concurrent thread running pertaining to synthetic oil use. Many are claiming that for many years they have had no problems with regular oil and/or extended oil changes. While this is probably true for gas engines since they use electronic fuel injectors, modern diesels are a whole different animal. Almost all the problems you hear about on these modern diesels are either emissions or fuel injection related. Clean fresh fuel and oil are paramount to long diesel life. Scrimping on either is a recipe for a low bank balance!
