I have a 2004 Volvo Penta outdrive with a 5.7gl engine. I’ve been having fuel pump issues. Stock P/N is 3858261. I had reasons to believe that my stock pump was going out so I recently purchased a new fuel pump that was cross referenced as the same pump. Claims to be 8 psi but is pumping harder than what the float in the bowl can withstand therefore causing fuel to be sent through the overflow into the carburetor. I installed the old pump and when it works, I don’t have the issue of the float staying open. I was wondering if anyone knows what the psi is on the stock fuel pump. Again P/N 3858261. Thanks!
