How to Service the Fuel Rail on a 3.3/3.8L Engine on Dodge Grand Caravan?

Always perform the fuel pressure release procedure on a 3.3/3.8L engine before you do any fuel rail service work. Unplug the negative cable on the battery and remove the upper intake manifold. During servicing, always use a cover to cover the intake manifold. Then, unscrew the fuel hose quick connect fitting attached to the bottom of the chassis tube and immediately wrap it with a shop towel to catch any gas that comes out. Afterward, take out the fuel rail bolts and lift the fuel rail out, being careful not to twist or break the O-rings of the injectors.

How Is the Fuel Rail Installed on a 3.3/3.8L Engine on Dodge Grand Caravan?

For starters, look at every O-ring seal around the fuel injectors and swap any O-ring that appears damaged. Coat every invisor O-ring with lighter engine oil and then fit the fuel injectors back into the cylinders marked during disassembly. Secure the fuel rail, insert each injector, add the retaining clips and confirm that every injector is like this. Place a thin layer of clean engine oil on the O-ring of every injector and set the injector nozzles into the openings in the lower intake manifold. Put in the fuel rail bolts and tighten them so they read 12 Nm (106 in. lbs.) when you check them. Attach the fuel injector electrical harness connectors to the right places and make the connections. Connect the intake manifold (4) and be sure to attach the fuel line connector correctly so no fuel can leak and ignite on your motor. Fit the quick connect fuel hose (1) into the fuel rail (2) and put the clean air hose on the throttle body. Next, hook up the ultra-sonic cable and tighten the nut to 5 Nm (45 in. lbs.), then use ASD Fuel System Test with the scan tool to put pressure on the fuel system and look for leaks.
