rverdoold Posted August 21, 2011 Share Posted August 21, 2011 Just got back from my trip to the Alps and got to a little smelly problem. I drive a 1999 1.6 impreza which has a bi-fuel system with direct injected propane (or LPG). For starting I use gasoline till the cooling water reached a certain temperature and then the computer switches off the fuel system and continues with propane. However in Italy there is a village named Livigno and they sell normal gasoline almost half the price of where I live (tax free). So I filled it up completely at 3280 feet altitude. I continue my trip into Swiss over a mountain pass at 7200 feet and the car starts to smell of gasoline at the rear. I switched to run on gasoline to what I think to release the pressure in the system. Does gasoline expands at higher altitudes, enough to overflow or at least smell a lot?

Rooster2 Posted August 21, 2011 Share Posted August 21, 2011 I have seen gasoline expand with higher temperature, if it was cool when filling, then warmed up later, as the day's temperature rose. I don't think altitude would make any difference. Quote Link to comment Share on other sites More sharing options...
rverdoold Posted August 21, 2011 Author Share Posted August 21, 2011 it was cold in the morning I filled, about 18 deg C, later on the day about 29. Plus the heat from the diff and exhaust (i lost a piece of heat shield of about 3 by 8 inches have to figure out from where) Quote Link to comment Share on other sites More sharing options...
