We bought a used cat paver a few months back and there is a bunch of rust in the fuel tank. Our paver operator keeps the tank full as much as possible to try to prevent a bigger issue. Hasn't caused a problem with the machine or fuel filters yet, but want to address it before that happens. Anyone every had to deal with this much? I'm trying to get some kind of plan together before we get into all the winter maint. In the shop. You guys are the first I'm turning to, haven't done any research yet.
