1985 Johnson 150GT Model J150 stlco, The vro2 has been diconnected for about 5 years, as I am running about half speed there is no problem but a full speed the engine acts like it is running out of fuel if I pump the bulb up she will run fine for a while and then do it again. Sounds like a fuel pump problem to me but not for sure.<br />My question is can I purchase just a fuel pump or do I need to purchase another vro2 even though I am not using the oil side.<br />Thanks Nebtnman
