If filter together with pump, then sorry case, very expensive to change. So far for my fuel injected cars one located at undercarriage between driver and rear passenger seat. My other car filter is in engine compartment.
My VR, I have seen mechanic take out fuel pump before, it has an additional strainer before going in to the pump and actual filter is in engine compartment before going to the injectors.
I changed mine once at 40k km and was pretty dirty already. I shake and pour out on white piece of paper, plenty dirt came out.....lol
Whether can last 80k km depends how clean the fuel you pump into your tank. Usually if can see the truck delver fuel to the station, I won't pump because when when they pump into their underground tank, may churn the dirt up from the tank floor.....lol
