Where is the fuel filter for a 2001 GMC Jimmy located.

Fuel supply problems like fuel pump , fuel filter or a plugged pick up screen in the gas tank.

Seems to be under the intake manifold.

its mounted to the top of the gas tank. see diagram below of what it looks like

For 2001 GMC Truck Jimmy 2WD 4.3L SFI 6cyl the Fuel Filter is located under vehicle, driver side, below seating area, near fuel tank, mounted on frame rail in fuel line.

Hope helps (remember rated and comment this).

RElease pressure,,by loosening gas cap,find filter,each end of line has a tab inside if not out if inside need tool can but at part stores ,,push tool around linr @ pull line watch for gas to run out!!!!

Fuel filter, but most likely a worn out fuel pump. The engine needs 62 - 65 PSI to start the engine. Anything less then that, the engine will not start. Start with the simple and check all your fuses and then check the fuel pressure with a fuel pressure gauge connected to the shredder valve.
The valve is located on the fuel line by the distributor drivers side, if the fuel pressure is less then that. Replace the fuel pump and the wire harness from the frame to the fuel sending unit.
Thank you for using fixya and good luck.

if its spraying gas you have a big problem is the filter put on right check the fuel rail there is a fuel pressure regulator connected to it it sometimes has a vacuum hose going to it . they tend to leak

fuel filter is located on the drivers side behind the rear quarter panel .

Check by lower rad hose in engine compartment, in fuel line.
