This is a discussion thread titled "tundra mpg change fuel filter", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
i just changed my tundra's inline fuel filter today wasn't requiring a change but i did it anyway and was very surprised how much junk was in my truck inline fuel filter i need to avoid those cheap gas station's .The part was sort of easy to get to but a major pain in the rear getting the two washers back on the inline filter...for anybody getting bad mpg you might too check your fuel filter's as well as your fuel injector to make sure you truck runs at peek performance....i noticed a big gain in mpg today ...what does most on this board get miles wise get on half of tank of tundra gas? if i recall its 22.3 gallon tank

Probably just a psychological effect of putting a new part on your truck. You want to believe that the effort and cost was worthwhile; therefore, you will likely perceive or do things to get the results you desire.
It is not likely that replacing your fuel filter will measurable affect your fuel economy. You might see a minimal increase in performance under high loads and WOT depending on what the pressure drop was across your old fuel filter. Under normal driving conditions, any lowering of pressure at your fuel injectors due to the gradually increasing pressure drop across the fuel filter would be compensated for by increased pulse width on the injectors by the ECU. That is the benefit of closed-loop engine management systems. The system will do everything possible to maintain the proper air/fuel ratios. If anything, a high pressure drop across your old fuel filter would likely tend to increase your fuel economy at the expense of all out performance.

I get between 225 and 250 miles to the first half tank and I typically get 16-18 mpg, but that doesn't mean much since the fuel gauge isn't linear. It is only useful as a comparison from one fill-up to the next. I usually get about 150 miles on the second 1/2 of the tank till the low fuel light turns on.
I replaced my fuel filter at about 130k. I didn't notice any difference, performance or mileage wise - but I always run good gas. I typically get about 380 miles on 23 gallons of gas

Originally posted by hovisimo your filter must've been really clogged. how many miles since you last replaced it, or was this the first time? i did mine at 30 then again at 60.
ryan,
well it was my first time replacing it since new miles mark right now is around 72k ....

If I drive carefully, I can get 300 miles on the first half, but that doesn't mean you can go 600 on a tank! My best is about 500 miles. I think some of the guys with V6 manuals have gone better than 550 though. I just got back last week from a 1000 mile trip and did two fill ups. One I got 20.4, and the other 20.6 MPG. It will also run 0-60 MPH in 7.5 -7.6 seconds, but not while getting 20 MPG!

I only get about 293-305 miles per tank! Usually about 12.7-13.8 mpg. This thing eats gas but then again it's all city driving. I have to fill up at least once a week. Before this Tundra, I had a Honda. Put $10 worth of gas in it and it ran for a good week and a half to two weeks. Tundra was a shock in gas mileage but it's worth it. I really like the truck. Except for the severe lack of aftermarket stuff.

so how much is that in-line filter? it's about ten bucks or so, right?

how much is the filter inline if you buy it from a toyota dealership it's 30 dollars which in my opinion is too high thus i got mine at auto zone for 14 dollars's not bad but than again not paying toyota for the same part they buy and put there name on....It is hard sort of putting them on my problem was my line's were so into the filter i had to be carefull not to break them moving them wile i uninstalled the old filter and i also got gas in my eyes(wear goggles when doing this)

manual actually sez to unplug the fuel pump (disconnect the fuel pump connector), then let the engine idle til it stops on its own to release the pressure in the fuel line, then unscrew the downstream end of the filter first. might keep gas out of eyes, mouths, etc...gonna try this here shortly after i clean the garage
ARG! something is wrong...did you have any problems with the new filter not sealing properly to the lines? mine is dripping from the front! im hoping i didn't just really screw something up...i'm gonna start a different thread on that...
otherwise, alls you need is an 8mm socket to loosen the filter clamp, and a 14mm wrench to loosen the fuel lines. loosen and replace the gas cap first tho to release the line pressure from the tank up, or it will drip for a long time (until i realized what was happening, duh).
those lines are really, really in to the filter. im going to take off the new one and make sure i didnt mess something up
tundra mpg change fuel filter
.The part was sort of easy to get to but a major pain in the rear getting the two washers back on the inline filter...for anybody getting bad mpg you might too check your fuel filter's as well as your fuel injector to make sure you truck runs at peek performance....i noticed a big gain in mpg today ...what does most on this board get miles wise get on half of tank of tundra gas? if i recall its 22.3 gallon tank
