Last year i've changed all my fuel hoses to clear fuel rated hoses. Something i've observed while starting my motor this year is that there's some fuel at the pulsar hose coming back into the pump from the block... it doesn't seem like it's causing issues since i've blocked-off the oil injection. But I supposed this isn't normal cuz if my oiler wouldn't be bypassed it would mess up the oil mix ratio no?
It isn't like a big amount of fuel but there's some. Usually this hose isn't see trought so no idea if it was doing this before.

also while looking at my fuel pump and the ones from crowley marine none of them have a pulser hose fitting... they all have one in, one out, and one oil in. can't seem to find one exactly like mine. see picture
