Fuel Pump Connections

This summer my son, his girlfriend and myself bought 1979 hydrostream vamp w/ 1979 140 hp mercury on it.  The past owner spent $300.00 carb. r/r and parts but no fuel pump overhaul. All this because of a bogging and no power-up problem.  It starts right up, has 120-130 between all six cyl. comp. Doing a link and sync. by the book to make sure it wasn't messed up.  The fuel pump diaphragm had a worn through section and two kinked hoses coming from the case and cylinder connections, so it got fixed.  However I'm wondering if I got the connections backwards because of massive gas consumption?  I did switch them around and it started up good, but it needs to be lake tested.  We really have enjoyed redoing the interior, repairing the trim motor and electrical system, it has gone well for us. And its good to know there are people such as yourselves that can help.

Thanks

Hope you got it tested before Ice up. Without a picture I really cannot answer if they are on right. Either way it would not make it use more fuel.
