Yup, definitely looks like the part. I just didn’t want to break anything and wanted to avoid the headache. The plastic pieces aren’t to strong and on the thin side so extreme caution is needed.

 

@Jeff Lange These don't seem to carry any kind of maintenance cycle...

Does the book ever mention at what point the primary filter needs to be changed?
Or only upon failures, which we are not seeing..

Also is the bottom screen filter included in that hanger assembly? Or is it another part # ?

It’s a separate part. Do not recall the part #. You can also just get the mesh or use the mesh that comes with an aftermarket fuel pump.

 

I know they sell the smaller filter on Rockauto. I think it's located under strainers? As for the OEM part number, I'm unsure what it is? As for the maintenance cycle, I believe there is none and I don't remember seeing it in the owners manual. IMO it's replaced upon failure due to the fact it's located in the fuel tank itself, does not have a secondary outer filter like some other vehicles do, it's more of a chore to replace due to location and Toyota doesn't seem to have a track record of failed fuel filters/pumps. Eventually though, it's got to be replaced because as we learned through time and time again about Toyotas "lifetime anything", nothing lasts forever.

 

You got to wonder if a partially clogged fuel filter could result in a lean condition for the guys who are supercharged? Needing that HPFP to fire at 100% duty cycle would necessitate maximum flow...

 

It's a possibility. I wonder if the supercharged guys even bothered to change out theirs or not? I would like to change mine out due to high mileage (153K+ miles) and get it out of the way since my car is going to be in the shop again as soon as I come back. It's not a problem for me but I might as well get as much done at the shop as possible and that's if they are willing to do it.

 

Fuel filter service life isn't time based, it's fuel based. If you get a load of bad fuel - sediment or other solid contaminants, then sure you need a new filter, but if you don't, it won't matter if you change it or not. This is why it's not on the maintenance schedule. It's pretty rare these days to get a load of sediment in your fuel. Yes, if your station had old underground tanks in bad shape you might very well benefit from this. The majority will not.
