Where is the fuel filter? - 2007 Saturn VUE FWD 4

Fuel Filter
The fuel filter is contained in the fuel sender assembly inside the fuel tank. the paper filter element of the fuel filter traps particles in the fuel that may damage the fuel injection system. The fuel filter housing is made to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. There is no service interval for fuel filter replacement.

2 of them........First Fuel Filter

One fuel filter is in the fuel pump of the Express Chevy 3500, which is used to push fuel or gasoline through the fuel line. The fuel pump is inside the gas tank. This fuel filter is a mesh or screen that prevents large foreign particles for entering the fuel pump. Access to the fuel filter is obtained by removing the fuel tank and then the fuel pump from the fuel tank.

Second Fuel Filter Location

The second fuel filter is within the fuel line itself. After the fuel pumps extracts fuel from the gasoline tank and into the fuel line, fuel flows through the line and through another filter on the driver's side of the Express Chevy 3500 under the front wheel suspension. This fuel filter cleans the small particles that escaped from the fuel tank.

Fuel Filter Types

The year of your Chevy Express 3500 determines what type of fuel filter is installed on the van. The fuel tank filter is always mesh or screen, but the fuel line filter can be of three different types. Two types are snap-on filters, while one type has clip-on ends.

The fuel filter is contained in the fuel sender assembly inside the fuel tank. the paper filter element of the fuel filter traps particles in the fuel that may damage the fuel injection system. The fuel filter housing is made to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature. There is no service interval for fuel filter replacement.

IMPORTANT: This vehicle has a lifetime fuel filter built into the fuel sender inside the tank and thus is not serviceable separately. The fuel filter is not a replaceable part.

your diesel engine should have a center bolt holding fuel filter it in place.you place drain pan under fuel filter when you remove top center bolt while holding fuel filter then remove old fuel filter then take new fuel filter add few ounces clean diesel fuel in new fuel filter lubricate gasket new fuel filter cartridge then install new filter crank engine check for leaks.

Fuel Filter Removal & Installation To Remove:
NOTE: There is no maintenance schedule for fuel filter replacement. Replace the fuel filter if restricted. Inspect the fuel tank internally if you find a restricted fuel filter.
Typical inline fuel filter

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Relieve the fuel system pressure.
3. Raise and safely support the vehicle.
4. Remove or disconnect the following:
   • Quick connect fitting at the fuel filter inlet
   • Fuel filter outlet fitting from the fuel filter while holding the filter fitting with a back-up wrench
   • Fuel filter from the vehicle
   • Fuel line O-ring.

To Install:

1. Position the new fuel filter in the bracket.
2. Install a new plastic retainer on the fuel inlet line.
3. Lubricate the new fuel pipe O-ring with clean engine oil.
4. Install the fuel pipe O-ring.
5. Reconnect the fuel outlet line to the filter by holding the filter with a back-up wrench and tightening the line fitting to 20 ft lbs (27 Nm).
6. Lower the vehicle.
7. Pressurize the fuel system and check for leaks.

Hope this help.

Here is the steps for the removal and replacement...getting you the picture and location next. 6.6L Engine

1. Disconnect the negative battery cables.
   
2. Drain the fuel from the fuel filter as follows:
   
   • Install a hose on the water drain on the water-in-fuel sensor.
     
   • Place the other end of the hose into an approved container.
     
   • Drain as much fuel as possible from the fuel filter housing.
     
   • Tighten the water drain on the water-in-fuel sensor.
     
3. Remove or disconnect the following:
   
   • Water-in-fuel sensor harness connector
     
   • Fuel filter from the fuel filter/heater element housing
     
   • Water-in-fuel sensor from the fuel filter

To install:

1. Install or connect the following:
   
   • Water-in-fuel sensor in the fuel filter
     
   NOTE Check the fuel filter/heater element housing and the filter for a dislocated filter seal or foreign debris. Contamination on the filter/heater housing may cause leakage at the fuel filter. Coat the seal with clean engine oil.
   
   
   • Fuel filter on the fuel filter/heater element housing

Hi,

Regarding Fuel Filter - Under vehicle, driver side, below seating area, front of fuel tank, mounted on chassis in fuel line.

A device located in the fuel line to remove impurities from the fuel before it enters the carburetor or injector system.

INSPECTION

Fuel filters can be located in a fuel line, in the tank, in a carburetor, or in any combination of these. A carburetor often has a filter behind the fitting at its fuel inlet.

An external fule filter. Courtesy of General Motors Corporation, Service Technology Group. Engine heat causes fuel to vaporize, which can result in vapor lock in the filter. Some fuel filters have vapor return lines to allow for expanding vapors and fuel to return to the tank.

REPLACE

Fuel filters and elements are serviced by replacement only. Some vehicle manufacturers recommend fuel filter replacement at 30,000 miles (48,000 km). Always replace the fuel filter at the vehicle manufacturer's recommended mileage.
The fuel filter replacement procedure varies depending on the make and year of the vehicle and the type of fuel system. Always follow the filter replacement procedure in the appropriate service manual. The photo sequence below shows a typical procedure for relieving fuel pressure and removing a fuel filter.
Removing a Fuel Filter on an EFI Vehicle



Disconnect the negative cable at the battery.



Loosen the fuel tank filler cap to relieve any fuel tank vapor press

Connect the fuel pressure gauge to the Schrader valve.




Install the free end of the gauge bleed hose into an approved gasoline container, and open the gauge bleed valve to relieve the fuel pressure.
