Anybody have experience with this pump? Strange symptoms. It's clean, won't move fuel through it. As soon as I disconnect the fuel line, the fuel that it pulled in, but did not discharge, then discharges and looks like good flow. Lasts only may maybe 2 seconds of course as the full line is disconnected. When I reconnect, it will not move fuel. Seems like strange venting issue ....if that's a thing on these
Thanks.
