    Question regarding 1999 Volvo Penta 5.0GL and power to the fuel pump relay

    Not sure exactly the sticker on the inside where the wiring harness plug mates together says 5.0 GL PWTR. Where would I look for the "B" or "C" designation?? Thanks-Geoff

    Greetings! First post even though I signed up in 2023. I have a couple of questions: 1. Have a '99 Volvo Penta 5.0GL with I believe a fuel delivery issue; when searching the forum I see the 4.3GL threads....do the two engines use the same fuel systesms (i.e. if I read the 4.3GL posts - is it...
