I know you said poor quality, but it was 98 from the servo at Bella Vista (sunday), brand I cant remember, and all previous fuel has been 98 out of the BP/macdonalds on Cowpasteur Rd at Cecil Hills. One thing I have noticed of late is when I open the fuel cap, which I do slowly, I get great amount of schussing, either air in or pressure out. But I open the Falcon sitting right next to it and there is NO pressure at all. Of course one may seal better than the other. I wonder, cold night, partial vac in tank, start up, pump labours against vac, engine misses and farts around, turn a few corners, fuel sloshes, gives off vapour and voids the partial vac. QUESTION: Are fuel caps /tanks supposed to hold pressure or vac in the tank. I thought the cap was suppossed to vent to atmosphere, and that charcoal canister thingy was supposed to suck all vapours out of the tank ????.
