Do I need to change fuel pump/strainer/filter? Is the filter inside fuel tank, how to change? https://www.lazada.com.my/products/...l__null__null__null__&scm=1007.16389.126158.0 https://www.lazada.com.my/products/...4k.searchlist.list.20.34f7350erAIagj&search=1
Silly question. How can we know the answer unless we know what is wrong with your vehicle? Take it to a mechanic.
The relevant change intervals will be in the manual. My guess it will not need changing at all, unless you are having problems with fuel flow. N.B. if the vehicle is fuel-injected, I would under no circumstances dick about with the fuel system myself. There can be high pressures and a real risk of an engine fire if you cock it up.
It would be a bit odd to put the fuel filter in an inaccesible(ish) location on the car. The ones I've dealt with were mounted on the undercarriage close to the tank.
I believe the fuel filter for your vehicle is just behind the transmission stick cover. There are youtube videos on how to change it.
I have had the 6.5L diesel pickup truck for 24 years/ 130,000 miles and have changed the fuel filter about 5-6 times. Read the owner's manual.
