"Ok, now I get it. I didn't realise those were the small header tanks w/integral fuel pumps. Makes more sense to me now. Bob Jones has the only 701 in our area, that I can think of, flying around on floats and skis. "
"If you're talking about the Viking 130, the pumps at the header tank push fuel at around 42 psi to the high pressure pump (attached to the engine), which then boosts the pressure as high as 2,200psi. "
"According to Evans, if there is significant coolant loss and no Evans waterless coolant is available to fill the system, it is ok to fill with water or a water-based coolant. Repairs should then be made as soon as possible, and the system should be…"
"Purchased the filter from Viking. I don't remember the brand filter but they're common. Our fuel goes through two other filters before reaching this one. Filters installed between each wing tank and the header Tank, and each fuel pump has its own…"
