Bro, In my case Air is comming IN the tank that is why I am alarmed. I think Only Petron Blaze is the only pure gasoline (not blended with ethanol) being sold here. Pero hindi ko pa siya nasubukan. since ni release ung innova namin petron extra unleaded lang pinapa karga ko. I try ko i check ung filler cap mamaya pag uwe ko. baka marumi din. so aling part ang culprit?
Fuel tank assembly?
As experienced lahat ng sasakyan sa family(both efi and caburated) lahat sila puro POSITIVE pressure or when you open the filler cap...air is comming out of the tank.
1992 Toyota Corolla 1.3(carb) - Mine
2001 Toyota Revo 2.0(efi) - My Uncle's
2003 Toyota Revo 1.8(efi) - My Father's
2010 Honda Civic 2.0(efi) - My Uncle's
Lahat sila POSITIVE pressure ang meron...bukod tangi ung innova namin ang pahigop pag binuksan filler cap.
Madali mo namang malaman kung air/(actually vapor) is coming out of the tank...
Amoy gasolina from a distance when you remove the fuel cap...
Ang sabi sa article,- the canister works when you turn off the engine...
Further,- walang breather ang tank filler cap,- dahil nga dapat trapped ang fuel vapor at ia-absorb ito ng canister when you turn off the engine, and then ipu-purge out when you start the engine... (Please refer to the previous article I posted)The canister goes unused until the car is turned off again.
So, the system requires a sealed gas tank filler cap....An evaporative control system was developed to eliminate this source of pollution. The function of the fuel evaporative control system is to trap and store evaporative emissions from the gas tank and carburetor. A charcoal canister is used to trap the fuel vapors. The fuel vapors adhere to the charcoal, until the engine is started, and engine vacuum can be used to draw the vapors into the engine, so that they can be burned along with the fuel/air mixture. This system requires the use of a sealed gas tank filler cap.

Thats a relief, thanks CVT. Saken papalabas yung hangin, parang nag exhale normal lang pala yun?
Even my gas tank warped last time i haven't experienced na papaloob yun pasok ng hangin.
Ako most of the time shell super unleaded pinapagas ko, next option is petron extra unleaded.
Sir mile, pwede po pa explain paano ang DIY ng charcoal canister. Di po ba delikado gawin to? baka magkalat tayo fuel?
pansin ko sa isang hose ng charcoal parang papunta man yun sa baba left wheel parte yung hose na walang clip. di kaya barado yun? breather ba yun ng charcoal canister?
