"First summer with my new-to-me boat (2004 Larson LSi) Volvo 5.0. Can someone help me trouble shoot this? Had it out this weekend (4th or 5th time so far).

Original pumps are sorry....... convert and you will have the fuel you need."

"Thanks, guys. I don't think it has ever been changed by previous owner, what a nice present for me! Mikewilly, did you find the racing fuel pump at a chain auto parts store or did you have to go to a NAPA type store? Would it be for a Volvo type car engine? Any specifics would be appreciated!"
