Default Location of fuel filter?

Since my Blazer spent an overnite in the Home Depot parking lot and can't check it out right now, where is the fuel filter on 95 Blazer 4x4? And, is there an access door in the floor to get to fuel pump or do I have to drop the tank? Thanks, Pete

Umm so you want to know where the fuel filter is or the fuel pump? The fuel filter is a little behind the drivers door on the frame rail. The fuel pump is in the gas tank if your blazer is like my blazer, which is probably is.

Default RE: Location of fuel filter?

The fuel filter is located on the inside of the left side frame rail.

When the ignition switch is turned ON, the VCM energizes the fuel pump relay which powers the in-tank fuel pump ON. The in-tank fuel pump remains ON as long as the engine is cranking or running and the VCM is receiving the distributor reference pulses. If there are no reference pulses, the VCM shuts the fuel pump OFF within 2 seconds after the ignition was turned ON or if the engine stops. The VCM will also turn ON the fuel pump for 2 seconds when the ignition is turned to the OFF position.
Should the fuel pump relay or the 12volt relay drive from the VCM fail, the fuel pump receives a supply current through the oil pressure switch backup circuit.

Do you hear the pump run when the key is turned to the on position?

An inoperative fuel pump relay can result in long cranking times. The time necessary for the oil pressure to reach the pressure required in order to close the oil pressure switch and supply the necessary current for the fuel pump causes the extended crank period.
