i have a 1989 johnson 110hp with the vro pump. it is leaking on the fuel side from the diaphram. i have inspected the whole pump and it looks fine. the diaphram looks fine as well. i cannot figure out why it is leaking. so my question is should i rebuild the pump with a kit or should i replace it with a non vro pump and mix myself? if i do replace it can someone tell me what pump to replace it with? thanks joel
