The fuel deli very module flange i s s eal ed to the t ank wit h an O-ring and s ecured wi th a locki ng ring.
The lower part of t he fuel deli very module forms the fuel del ivery pot , and provides the locat ion for the in-t ank pump andt he 2 jet pumps . The delivery pot provi des a cons t ant res ervoir of fuel for t he engine drawn fuel supply. The engine fuels uppl y and ret urn l ines are immers ed in the del ivery pot .
The delivery pot is mai ntained full by t he 2 jet pumps . The i n-t ank pump draws fuel from wit hin the fuel deli very pot andforces the fuel t hrough t he 2 jet pumps . The flow of fuel t hrough each jet pump creat es a venturi effect t hat draws fuelfrom bot h s ides of t he fuel tank i nto the fuel deli very pot. Surpl us fuel entering the fuel deli very pot overflows into theus abl e s ide of t he fuel t ank.
A valve i s l ocated in t he l ower (usabl e tank s i de) jet pump s uppl y ori fi ce. The valve i s open when the i n-t ank pump isenergized and t he lower jet pump is s upplying fuel i nto the fuel del ivery pot . The val ve wil l cl os e when the i n-t ank pump isde-energized t o prevent fuel drai ni ng from the fuel del ivery pot .
The in-tank pump is energized by t he fuel pump relay l ocat ed in the Cent ral Juncti on Box (CJB). The Engine Cont rol Module(ECM) energi zes the fuel pump relay at al l ti mes when t he ignit ion i s in power modes 4 (Acces s ory) t o 9 (Engi ne crank).For addit ional informat ion, refer t o: Electroni c Engi ne Controls - 2.2L Dies el (303-14 El ect ronic Engine Cont rols - 2.2LDies el, Des cript ion and Operat ion).

The modified fuel del ivery modul e incorporat es a s eparate fuel supply line that connects t o anauxi li ary fuel pump, mounted on the ext erior RH si de of the tank. An addi ti onal fuel l ine connects the auxil iary fuel pumpt o the fuel fi red boos ter heat er.For addit ional informat ion, refer t o: Fuel Fired Boost er Heat er (412-02B Auxi liary Cli mate Cont rol , Des cri pti on andOperat ion).
Fuel Sender Units
The 2 MAPPS fuel s ender uni ts are located on eit her s ide of t he s addl e s haped tank, and connect t o t he int ernal elect ricalconnecti ons on the fuel del ivery modul e fl ange. Each s ens or provides an elect rical signal t o t he CJB t hat i s proport ionatet o the fuel level i n each s ide of t he tank.
The act ual fuel level i n t he t ank i s calculated by the CJB and t rans mit t ed via t he medium s peed Cont roll er Area Net work(CAN) bus t o t he ins t rument clus ter.
A warning l amp is incorporat ed in t he i ns t rument clus ter and wi ll il lumi nat e when t he fuel l evel is at, or below apredetermined l evel . On vehi cles wi th a high-l ine i nst rument clus ter, a mes s age is di spl ayed and a chi me i s s ounded t oinform the driver to refuel .
