Hi there, isn't the pump supposed to be on the other side of the Racor, pulling it through there? This just from memory. Reading this thread, it seems that the 34, or perhaps the 3HM35F requires a lift pump, while the 37 has installations that does not require an auxillary lift pump. Can someone confirm this?
Mine has another brand PO installed a few years ago, but not a Walbro. I can't remember what kind, and my mind won't get away from facnor, but I know it is not a furling pump
At any rate, I do want to get a spare.
