Dear Waqar sb,
Fuel filter for 250 ?. I brought for 660 china one from Montgomery and later on Toyota had me replace with original one for 6800 or so. but my problem of long sulf was not solved and only solved on replacing fuel pump about a month back .
Before the whole assembly could be purchased new for around 4,000 some years back and this was supposed to be changed after 40,000 km.
Now unless needed, do not take out the assembly or fuel filter unless there is a need to . The fuel pump get affected and the return valves stop giving the proper fuel pressure
