Well I removed my vro pump and replaced it with a new double piggyback style fuel pump. Took it out, ran like crap. Came back and noticed all six of my float bowls were cracked in the same place. So I replaced my float bowls with new ones. But being a rookie I didn't do my homework before hand. I did not know that there was a high speed jet behind the drain plug on the float bowl that needed to be removed from the old and installed on the new float bowls. And I threw all the old bowls away before I learned of the jets. So now I need new jets to put in my new bowls and figured I'd replace all of them while I had em off. Just don't know which ones to orderExplain.-----What is your motor doing / not doing ?----What elevation are you running at ?-----Which jets do you want to change and why ?----The 150 and 175 hp jets are listed together.
