This is why you should change your Fuel Filter

[z287mgte]

Car has been acting a little weird so I decided to replace the fuel filter. This is what mine looked like.

Both of these are post fuel filter. I let the fuel settle for a little while.

This is what the same bottle is shaken.

I was scared that this was coming from the tank so i took off the other end and this is what came out (before filter)

This is what they look like together. So yes this is what was going to my injectors. I showed this to some friends and they are now going to change there fuel filters as well.
Hope this helps anyone thinking about not changing your fuel filter...
Car has 150,000 miles, Turbo, 88

what kind of symptoms did you have?

 

[Heavy D]

i should do mine, same year turbo and about the same mileage

I was having sporadic idle and wot a/f was also sporadic. Drove 2 hours home and never went wot but idle seemed a lot better. Need more time to see if anything else has differed. Going to sonic clean fuel injectors soonish and hope to see a big improvement.

wow never thought about it like that. Thanks for the info

As the voice of reason... it's a LOT easier to test for flow and pull a sample than it is to change the filter. Furthermore, the fuel filter on the Supra is engineered to last basically forever.

Not saying that the OP's isn't pooched, just that I suspect it's the exception rather than the rule.

I agree. I actually read that long ass article about the Supra's fuel filter.

I read that article as well and i think it said that after 20 years it should be changed. Well guess what 20 years is upon us. The reason mine looks like that is because its been 20 years and after 20 years things tend to rust up. You can get a fuel filter for $4-$18 and would you rather be safe than sorry. Took me 1 hour to change and glad i did it. It is a true small price to pay to have a little peace of mind.

I replace them in any car I buy I figure it's cheap insurance and not worth the risk of losing an engine over $20 and some frustration fitting the new one.

 

[Jamie-B]

Does anybody have a part number for the fuel filter?
Im guessing im probably going to have to order one in as my local car shop is pretty useless, and im pretty sure the fuel filters on these are quiet different than the regular inline filters?

+1. I understand how--theoretically--the fuel filter should last the life of the car, but you never know what's gotten in the tank over 20 years. Plus, most of us install aftermarket fuel pumps and with the tank out it is easy as pie to change! (that's how I did mine).

 

[modmonster2008]

hope its not a noob question but where is the fuel filter located on the mk3 supras?

 

[GrimJack]

It's above the rear differential.

 

[IwantMKIII]

I've replaced all fuel filters on my supra's and cars previous. EVERY TIME, I have the same results as OP.

 

[ForcedTorque]

It's above the rear differential.

Or, rather, it's behind the differential, in front of the gas tank. Much easier to get to when the tank is out.

So, are you saying the fuel was going into the filter clean, and coming out filthy? Something doesn't add up.

Sorta like running clean water through a tea bag

 

[whitemike]

Is OE the only way to go then?

 

[z287mgte]

I don't get it either. Went in clean, came out dirty.(Just like a tea bag) You can get a fuel filter anywhere, does not have to be by Toyota. (Either it is old rust from the tank or fuel filter was rusting to hell. Or both) Want to check tank the tank one day to be sure.

How does it not, it's a filter, and over time they get dirty. Now imagine a 20 year old or even 10 y/o filter constanly being used every time the car is on, it's going to get very very dirty with lots of buildup as any other filter would.
