step, no clue how old anything is. somehow, whoever installed or changed out put the bulb in so there's absolutely no extra play in the fuel line. the bulb is way down inside the fishbox, between the inner wall of the transom well and the batteries. it's a real ***** getting a hand down in there even to squeeze the bulb. changing it out without doing the fuel line seems almost impossible. maybe 20 years ago, or even just a few years back when i could still do some mechanical yoga.... at this point and approaching 60 years old, if doing more will actually be easier, and for the few extra buck for fuel line i figure what have i got to lose. it'll be less work for me to change out more in this case.
i didn't even think of running it off the auxiliary tank. i'll try that over the next couple days before i start ripping everything out.
