I looked and it doesn’t look dirty but you can only see so much it still had over a half tank of gas in it and that race gas is blue so maybe to hard to say for sure but it could be coming from the passenger side because there’s a rubber hose that feeds fuel back on top of the pump which I believe is a siphon from the passenger side tank and the dealer had it apart two times because the secondary sending unit kept throwing a fault they fixed it once and it went about 600 miles and then they had to do it again and the second time they even said they put a new pump in as well they had it about two weeks both times
