I had strong fuel odor after shut down at RR wheel well. Turned out to be
corrosion around the banjo bolt was just enough to weep fuel out but not
enough to overflow the tank cap where the banjo bolt is. This was also the
cause for long hot crank times - would bleed pressure out of the line (verified
by manually activating the fuel pump before start, could be heard as well).
Replaced cap/sender fixture, fuel pump done at same time (had 86k on it) -
both problems solved.
