comes to think of it, your SA also quite a xin ga lan wor, such a weird theory. However I think I'm another bigger XGL. Plain XGL, never have a 1st hand petrol leaking experience before, so if you choose to look see what I have in mind, read on.
If you know how is the high quality NGV being produced? Everyday millions of gallons of crude oil being transfer via pipeline from Alaska oil foundation back to the States. In between the transfer, evaporation occurred, part of the precious oil has become GAS. Oil company will suck out those gas halfway at the pipeline and further refine them for road vehicle use. So, our car also produce NGV everyday when the petrol in our tank evaporize, that is the air pressure being release "psssttt" everytime you open the fuel cap to fuel up.
Now, if you leave more space for the petrol to evaporize, do you think the air pressure will be less than if you pump full tank?

on the otherhand, the fastener has a locking mechanism ON the fuel hose. Besides, the hose end joint also has a knot that will jam the hose from ejecting. If it leak, it leak; if it doesn't, it doesn't. Meaning that if it doesn't leak, it will last for a very long time until the hose start to hardened and crack. So far all my cars only my 1973 MAZDA RX-2 leak petrol before. Lately I just rechecked my fuel line of my Iswaga(1996) and those hose are still in working condition. No sign of hardened yet

So, choose what you want to believe lar. My dad bought his Wiga, immediately full tank. My bro bought his BiBa, immediately full tank. My aunt bought her Elite, I also full tank it when we go take car together. What about other GaGa owner?
hahahah. bro, it just the story. i didnt expect myself to believe
by the way, why need FSB? our car already lotus handling. those need FSB are one that really serious play their car at track. do they?
