    I have a Maxforce 13 with a fuel leak . On top of the pump there are 2 fuel line adapters? one of them leaks from a crack. are these just bolt on replaceable?

    They are not replaceable from the dealer, but I’ve heard there are aftermarket parts available, never seen it though. Used or scrap yard might be your best bet.

    Have you replaced these pumps? If so is it straight forward or is there any tricks or odd tools I might need?

    It’s pretty straightforward. The pump and front housing come off as a unit then you can split it on the bench. There is a puller to remove the gear from the pump but you can always just hit it out if your changing the pump.

    Do I need to replace the high pressure fuel lines?

    Do you know the fuel line torque?
