Had to pull the oil tank after some genius thought it was the gas tank. After I put the oil tank in it was a nightmare reconnecting the oil line and a lot was spilled lol. Anyway when I start it it's reading oil low. Is this normal? I'm sure there's some sort of air in the line from the actual oil tank nipple fitting to whatever line it connects to. I installed a brand new oil tank last year so I'm sure I had the same issue but it was during the fall and I never really ran it other than on a trailer so maybe it had time to gravity feed? But isn't the sensor telling me this from the amount in the actual tank? I probably have less than a gallon in the tank
