When I'm at about a half tank of fuel my fuel tank lines or Raptor lift pump hoots at me. I hear it more when running uphill or slosh the tank on rough grades. When this sound occurs I can watch my fuel pressure drop suddenly too.I think it is the DS sloshing around and loosing its seal and suck air. Not sure about this but it stops when the tank is full.I was thinking about a billet tank sump so the L/P is somewhat gravity fed. However, DOT has a rule that a tank sump is illegal incase of a fires in a wreck.Anyone know about this? I understand my insurance could decline coverage if they found out.
