To locate the inline filter, follow the fuel line back from the carburetor or throttle body. Inline filters are often mounted to the frame rail underneath the vehicle. It may be necessary to raise and safely support the vehicle using jackstands in order to access the filter.
1.Properly relieve the fuel system pressure.
Some late model vehicles are equipped with "quick-connect'' fittings. A special tool must be used to release the locking tangs on these fittings.
2.Using a backup wrench (on threaded fittings) to prevent overtorquing the lines or fittings, loosen and disconnect the fuel lines from the filter. Be sure to position a rag in order to catch any remaining fuel which may escape when the fittings are loosened.
3.Remove the fuel filter from the retainer or mounting bolt. For most filters which are retained by band clamps, loosen the fastener(s) and remove the filter. For some filters it may be necessary to completely remove the clamp and filter assembly.
4.Position the filter and retaining bracket with the directional arrow facing away from the fuel tank, towards to carburetor or throttle body.
The filter has an arrow (fuel flow direction) on the side of the case, be sure to install it correctly in the system, the with arrow facing away from the fuel tank.
5.Install and tighten the filter/bracket retainer(s), as applicable.
6.Connect the fuel lines to the filter and tighten using a backup wrench to prevent damage.
