Drivers side, craw under the drivers side door on your back and look up in the frame. unbolt both end and replace.
The fuel filter should be located on the driver side frame rail underneath the cab of the truck.
Because the fuel filter is located inside the fuel tank and is part of the fuel pump module. The fuel filter by itself is not serviceable.
I own a 1990 GMC Sierra 1500 5.7L V8. My fuel filter is located along the frame rail under the cab on the driver's side of the truck. You might look there for the filter on your 1989 Sierra. It's an inline silver colored canister.
drop the fuel tank. Bummer huh. :)

The 1999 GMC 1500 PU equipped with the 5.0L V8 have an undercar in-line EFI filter. The filter is located directly upstream of the fuel tank in the gasoline line going to the engine. The OEM AC Delco replacement fuel filter is #GF652.
its dirrectly under the driver side against the frame rail
On the 2011 GMC Sierra 1500, the fuel filter is located inside the fuel tank as part of the fuel pump module. This design means that the fuel filter is not easily accessible for replacement, and if it needs to be changed, the entire fuel pump assembly typically needs to be removed from the tank. Regular fuel system maintenance, including using quality fuel, can help prolong the life of the filter.
The 2006 GMC Sierra 3500 SLE with the LBZ 6.6 Duramax does not have a cabin filter.
