I just changed out the impellers on my vyper and on the starbord side i cant for the life of me get the fuel pump to prime, any suggestions on priming a dry pump ? Oh by the way what a pain in the A@@ to get the pumps out. Almost gave up but finally got them.

spray carb clean down the carb and get engine started,
that should spin the pump fast enough to get fuel flowing.
be carefull doing it.
