Toyota Innova Gas Tank woes

[dr. d]

I also encountered this problem in my Innova's fuel tank last year. I often wondered what the thumping sound I hear under the vehicle. I later found out it was coming from the gas tank after I observed the vehicle with the engine off in my garage. It was probably the tank expanding/collapsing due to the vacuum inside.

Eventually, the tank started to leak. Malas ko pa I was in Anilao at that time. I found a talyer and the mechanic placed a rubber strip under the leak to minimize the flow. Then I brought it to Toyota C5 where they replaced the gas tank with a brand new one.

After 8 months, I noticed my tank leaking again... at the same spot! I went back to Toyota C5 to complain and informed them that they should have replaced the charcoal filter and filler cap when they replaced the tank. I said it was likely the cause why the tank leaked again. Or maybe, they really did not my old tank and just repaired it that's why it leaked at the same spot again! The car is still in Toyota and I'm waiting for their assessment.

What do you think?

when i had gas cap cover problems before, i just got a generic cap cover and drilled a very small hole right thru.. no problem since. and no, i did not smell gas fumes by the drilled cap, neither did i suffer worse fuel mileage..
in the olden days, it was the tank itself that had a breather tube, and the filler caps were airtight thingees..

We had the same experience, though my 2nd tank replacement was free plus free charcoal canister and gas lid cap, since this was under warranty that time. I had a lengthy discussion with Toyota plus some demand letters that this is a factory defect. Gladly, since 2008 up to now the warping gas tank problem no longer seen in my unit.

That time Toyota dismantled my gas lid cap and the breather holes are gunk with black soot, as immediate remedy then while waiting for the replacement parts, they just removed the filter mesh for the breather holes and immediately no more pooping sound underneath after few minutes of engine off.

Sir Cast, Original Fuel Filter binili ko sa banawe. Di rin ako naghanap ng replacement. Anyway once lang naman every 80k odo ayon sa manual.

Mga paps, ask lang..

May nakaexperience na ba sa inyo na say for example nasa 1/2 pa yung gauge then naka idle ka lang for mga 5 minutes, bababa ng dahan dahan yung needle nya say for example hangang near 1/4, then kapag tumakbo ka na, balik normal sya sa 1/2.

yes, naka experience na po ako ng ganyan.... ang cause po nyan ay hindi pantay ang daan kung saan ka naka park.

Not really na nakapark na di umaandar engine, say for example heavy traffic and pantay ang daan, talagan bumababa sya ng dahan dahan, then kapag umandar ka na ulit, babalik na sya rin kung san sya dati.

I am thinking baka fuel pump, float or baka kailangan lang linisin yung tangke, di pa ata naibaba ang tangke nito, 2008 VVTi E.
