Have 80,000 miles on filter....shouldn't it be changed??
where is the fuel filter located on 2005 Isuzu Ascender
It appears that the fuel filter is located in the fuel tank on the fuel pump/sender unit. Although I do not have an Isuzu owners manual to refer to (if you have one - defniitely check it...if you do not, it would be a great idea to obtain one...), I would suggest that the fuel filter is not a normal maintenance item, and would not think to replace it for normal wear and tear at your mileage.
Thanks DaveJHM....Your info is very helpful....
