Petrol Cap

Helloo !!! dude..... fuel has FUME !!... a little spark can cause flame ;)

and fuel can evaporates too..
rain waters gets in, condensation from air.. would be bad for you engine :p

how can water get in ?

its not possible :)

and FYI i don't HOON like an idiot DUST
so don't talk shit.

Im not saying that you are a hoon, i was making an example. Having no fuel cap can endanger yourself and other people.

Thats why i was just wondering about it this morning when i woke up.

Is there any REAL issue of not having one ?

is this a serious question?

ever filled your car up at a petrol station? notice how easy it is to push the filler nozzle in there? its just a little metal flap. anything could get in there.

heck, i could hunt you down and put sugar in your fuel tank.

if youre stupid enough to drive your car around without one, you dont deserve your car.

So that is not a problem ?

So honestly that is not the only problem of not having a fuel cap ?

For cars with a returnless fuel system, not having the cap would cause a check engine light because of the drop in fuel pressure. Not sure what car you have, but the older cars didn't have this issue. Next would be the lighter fractions of fuel evaporating from your fuel and leaving through the filler hole, thus making your fuel burn with less energy and making fuel consumption worse. Then, you have the risk of water entering the fuel tank. If you look at how the fuel filler lid is positioned, rain water can enter between the gap and then splash down into the filler hole. Finally, if you let your car sit in the sun and have the fuel evaporate out your tank, someone standing next to your car lighting a ciggie could start a fire.

BTW, how did you lose your fuel cap? Did you do a lowie by leaving it on top of a fuel pump at the petrol station and then driving off? ;)
