I m pretty sure on the 89 model it would be located on the frame rail near the gas tank under the truck...GOOD LUCK
look back by the fuel tank by the frame on the passengers side
the fuel filter is an in-line filter next to the frame under the driver side
It is inside the passenger side rear wheel well.
along driver side frame rail by drivers door
On the frame ny the tank follow the line can't miss it
what's the pis of the 1990 v6 isuzu pickup fuel pump
Drop the tank and there is a round plate on the top where the hoses connect. The filter is on the end of the pickup tube inside the tank.
on the passager side just in front of the rear wheel. behind one of the bed supports
IF I KNEW I WOULD NOT BE ASKING
Where is my filter for my 97 ISUZU RODEO
In the fuel filter pocket
most fuel pumps on most cars are located inside the gas/fuel tank, unless there is an alternative fuel pump added post factory.
